Mitochondrial DNA is short compared to the nuclear DNA. External Customers. The nuclear genome is significantly larger than the mitochondrial, consisting of 46 chromosomes that contain 3.3 billion nucleotides. It is a nucleic acid and is one of the four major types of macromolecules that are known to be essential for all forms of life1.

Mitochondrial genome 1. Utilizing this greater mutation rate and these non-harmful mutations, scientists determine mtDNA sequences and compare them from different individuals or species. These two DNA strands are called polynucleotides, as they are made of simpler monomer units called nucleotides2. When people, who are studying it, get confused about the same kind of terms it can get very irritating. Mitochondrial DNA contains only thirty seven genes, all of which are important for normal mitochondrial function of which thirteen of these genes provide instructions for making enzymes while the remaining genes provide instructions for making molecules which help put proteins together.

Thus also leads to inherit any genetic disorders or illnesses from the parents if they have any. Alexander Hammond.

Methods have been developed that are used to track the ancestry of many species back through hundreds of generations and has become the mainstay of phylogenetics and evolutionary biology. Location → Located exclusively in the mitochondria, mtDNA contains 100-1,000 copies per somatic cell.

Mitochondrial DNA is found only in the mitochondria of the cell.

Also all mitochondrial diseases in a human being is associated from the maternal side through inheritance. 2.

The chromosomes in nuclear DNA are responsible genetic make-up of a human being while the chromosome of the mitochondrial DNA is responsible for the metabolic activities. Based on key structural and functional properties, these differences affect how they operate within eukaryotic organisms. It is basically the hereditary material in all organisms which is inherited from the parents of that organism. Keep it up. We do not implement these annoying types of ads! During cell division, chromosomes are duplicated through the process of DNA replication, as long as each cell has its own complete set of chromosomes. DNA stands for deoxyribonucleic acid, it a very complex molecule that has all the information to build and maintain a living thing or an organism.

Nuclear DNA is longer as compared to the mitochondrial DNA which is shorter. They are linear in shape.
Nuclear DNA and all the genes inside it are responsible for the structure, built and features of a particular human being as well responsible for the nature and traits of that person. On the other hand the mitochondrial DNA is found in the mitochondria of the cell only and it consists of only one chromosome which is only inherited by the mother. The mutation rate in mtDNA is much higher than in nDNA, which is normally less than 0.3%10. Nuclear DNA is located in the nucleus of our cells and it makes up 99.9% of the total DNA in our body. Different people have different features and characteristics which are inherits by the parents.

Apart from work, she enjoys exercising, reading, and spending time with her friends and family.

In Humans, the mitochondrial genome size is 16,569 DNA base pairs.

The shape of the nuclear DNA is linear while the mitochondrial DNA are circular in shape. Science and Biology can be subjects which become difficult for people who do not know much about them. nDNA follows the universal codon pattern, however this is not always the case for mtDNA.

Mitochondrial DNA is inherited solely from your mother because the fathers mitochondrial DNA is destroyed during fertilization. Eukaryotic organisms such as animals, plants and fungi, store the majority of their DNA inside the cell nucleus and some of their DNA in organelles such as mitochondria4. The greater number of mtDNA copies per cell than nDNA, also makes it is possible to obtain a DNA match with a living relative, even if numerous maternal generations separate them from the skeletal remains of a relative.

From these STRs, a ‘profile’ is obtained from items of evidence, which can then be compared to known samples taken from the individuals involved in the case. She has a master's degree in science and medical journalism from Boston University.

Inside the cells, the Nuclear DNA is made up of tiny structures which are called chromosomes. These chromosomes contain between 20,000-25,000 genes.
The nuclear DNA contains 20,000 to 25,000 genes while mitochondrial DNA contains only thirty seven genes. Each individual nucleotide is composed of one of four nitrogen-containing nucleobases – Cytosine (C), Guanine (G), Adenine (A) or Thymine (T) – along with a sugar called deoxyribose and a phosphate group.

Almost every cell in a human beings body has the same DNA.

This creates a chain, resulting in an alternating sugar-phosphate backbone. Human mtDNA can also be used to help identify individuals using forensics, however unlike nDNA, it is not specific to one individual but can be used in combination with other evidence (such as anthropological and circumstantial evidence) to establish identification.

Structure → Both types of DNA are double stranded. 3. A network of relationships among these sequences is then constructed which provides an estimate of the relationships among either the individuals or species from which the mtDNA was taken. Being semi-autonomous organelles, mitochondrion cannot code for all of its own proteins. Mitochondrial DNA or mt DNA is double stranded and circular. "Difference between Mitochondrial DNA and Nuclear DNA." We need money to operate the site, and almost all of it comes from our online advertising. Please add difference.wiki to your ad blocking whitelist or disable your adblocking software. It is a nucleic acid and is one of the four major types of macromolecules that are known to be essential for all forms of life1. the nuclear genome is made of 3.3 billion DNA base pairs, whereas the mitochondrial genome is built of 16,569 DNA base pairs; the nuclear genome is … Some mitochondrial coding sequences (triplet codons) do not follow the universal codon pattern when they are translated into proteins. There is no need to resubmit your comment. We've detected that you are using AdBlock Plus or some other adblocking software which is preventing the page from fully loading. Every organism has DNAs. Nuclear DNA is composed of the adenine, thymine, guanine and cytosine which are the main nucleotides and it consists of a double helix chain which is separated during division of various enzymes. Nuclear DNA is located within the nucleus of every eukaryotic cell (with some exceptions such as nerve and red blood cells) and usually only has two copies per somatic cell5. Nitrogenous bases of the two polynucleotide strands are bound together by hydrogen bonds, to make double stranded DNA according to strict base pairings (A to T and C to G)3. Deoxyribonucleic acid (DNA) carries genetic information that is used as a set of instructions for growth and development, as well as the ultimate functioning and reproduction of living organisms. Tabular comparison of key differences between Mitochondrial and Nuclear DNA. • One cell contains approximately 99.75% of nuclear DNA and 0.25% of mitochondrial DNA. • Categorized under Biology,Science | Difference between Mitochondrial DNA and Nuclear DNA. The mitochondrial DNA is a special circular type of DNA that is only found within the mitochondria only and it makes up only 0.1% of the total DNA in our bodies. Every single person has a unique genetic blueprint, even identical twins12.

Each mitochondrion contains dozens of copies of mt DNA.

This differs from mtDNA, which usually has a closed, circular structure and is not enveloped by any membrane. Mitochondrial DNA is not enveloped by a membrane. Human beings have forty six chromosomes in one cell which are arranged in pairs.

Humans contain between hundreds to thousands copies of mitochondrial DNA per cell.

However, mitochondrial DNA is haploid, with the single chromosome being inherited down the maternal side and does not undergo genetic recombination9. However, given the genetic instructions it holds for the development of all living organisms, scientists have recognised its use in forensics.

This article has laid out the main differences between the two types of DNA to give people a clearer understanding of them. Mitochondrial vs Nuclear Genome. Cite To compare these two kinds of DNAs first we need to understand what a DNA is. Both these DNAs are double stranded. Connect with her on Twitter @Janet__White. For nuclear gene transcription the process is monocistronic, where the mRNA formed has sequences coding for only a single protein8.

This involves using small amounts of nDNA to make copies of targeted regions called short tandem repeats (STRs) on the molecule13. To compare these two kinds of DNAs first we need to understand what a DNA is.

Genome sizes → Both mtDNA and nDNA have their own genomes but are very different sizes. Most DNA is located in the cell nucleus which is called nuclear DNA, but a small amount of DNA is also be found in the mitochondria which is called mitochondrial DNA. Nucleotides are joined to one another by covalent bonds, between the phosphate of one nucleotide and the sugar of the next. There are many variations among the codes used by mtDNA that arise from mutations, many of which are not harmful to their organisms. The basic genetic outlook of a human being is carried out by the nuclear DNA while the metabolic activities are carried out by the mitochondrial DNA. The chromosomes of the nuclear DNA are longer as compared to the chromosomes of the mitochondrial DNA which are shorter.

UGA also codes for tryptophan (not a stop codon as in mammalian genome)6. DNA stands for deoxyribonucleic acid, it a very complex molecule that has all the information to build and maintain a living thing or an organism. Nuclear DNA has most of the genetic information a person’s body needs while mitochondrial DNA contains only information needed for the mitochondria to work and also depends on the nuclear DNA for some assistance. The main difference between mitochondrial DNA and nuclear DNA is that mitochondrial DNA is encoded for the genetic information required by mitochondria whereas nuclear DNA is encoded for …

Because mtDNA has a greater number of copies per cell than nDNA, it has the ability to identify much smaller, damaged or degraded biological samples14. This gives an idea of how closely and distantly related each is – the more mtDNA mutations that are the same in each of their mitochondrial genomes, the more related they are. 5.
