Answer :
The letter A indicates nucleosome. The letter A shows a DNA double helix histones loop.
Deoxyribonucleic acid (abbreviated DNA) is a molecule that consists of genetic data for the improvement and functioning of an organism. DNA is a product of two linked strands that wind around every other to resemble a twisted ladder — a shape referred to as a double helix.
Deoxyribonucleic acid is a polymer composed of two polynucleotide chains that coil around each other to shape a double helix sporting genetic commands for the improvement, functioning, growth, and duplication of all acknowledged organisms and lots of viruses. DNA and ribonucleic acid are nucleic acids.
DNA is made up of a series of molecules called Nucleotides. every nucleotide consists of a nitrogen base, a sugar group, and a phosphate group. four viable nitrogen bases may be present in DNA; Adenine (A), Thymine (T), Guanine (G), and Cytosine (C). Human DNA includes billions of DNA bases.
