This form is unstable and doesn’t occur naturally in living organisms. C-DNA: This is the form DNA takes when subjected to relatively low humidity and specific ions like Li+ and Mg2+.Double strands of B-DNA run in opposite directions, and the two strands are held together by hydrogen bonds between the base units. B-DNA: Discovered based on X-ray diffraction patterns and existed under normal physiological conditions.Viruses adapt this form of DNA as an adaptive mode of survival in harsh environmental conditions. The double strands are antiparallel and formed by sugar phosphates using phosphodiester bonds. A-DNA: This appears when the environmental humidity is less than 75% and is rarely present under normal physiological conditions.There are also several forms of DNA based on structural diversity, as can

This type of DNA has a higher mutation rate than nuclear DNA. Mitochondrial DNA is haploid, meaning it comes from one source, which is the mother. Mitochondrial DNA: Mitochondrial DNA is present in the mitochondria, and each cell contains about 100-1000 copies.The structure of nuclear DNA is composed of 46 chromosomes, whereby 23 are from the father and the other 23 from the mother. Nuclear DNA or autosomal DNA: Nuclear DNA (nDNA) is present in the cell nucleus of eukaryotic organisms and acquired from both parents.There are two types of DNA the autosomal DNA and mitochondrial DNA. The frame is of alternating deoxyribose, which is a sugar and phosphate molecule. The structure was discovered in 1963 by James Watson and Francis Crick.

The DNA structure is a double helix that resembles a twisted ladder. Thus, every cell circulating in your body has the same type of DNA composition. DNA is located at the cell’s nucleus, but there is some DNA present in the mitochondria known as mitochondrial DNA. What are the Characteristics or Properties of DNA?ĭeoxyribonucleic acid, abbreviated as DNA, is the hereditary material present in almost all prokaryotes and eukaryotes.
