What is the composition of DNA?

Answer 1

DNA is a doubled stranded structure, while RNA is a single stranded structure. RNA contains the sugar ribose, while DNA contains the sugar deoxyribose. RNA can have 4 nucleotides: cytosine, guanine, uracil, and adenine. DNA can have all these nucleotides except for uracil, which is replaced by thymine

Answer 2

DNA (deoxyribonucleic acid) is a nucleic acid formed from a repetition of simple building blocks called nucleotides. The nucleotides consist of phosphate (PO4), sugar (deoxyribose), and a base that is either adenine (A), thymine (T), guanine (G), or cytosine (C). In a DNA molecule, this basic unit is repeated in a double helix structure made from two chains of nucleotides linked between the bases. The links are either between A and T or between G and C. The structure of the bases does not allow other kinds of links. The famous double helix structure resembles a twisted ladder. The 1962 Nobel Prize in physiology or medicine was awarded to James Watson (b. 1928), Francis Crick (b. 1916), and Maurice Wilkins (b. 1916) for determining the molecular structure of DNA.

Answer 3

DNA is composed of nucleotides, which are made up of a sugar molecule (deoxyribose), a phosphate group, and one of four nitrogenous bases (adenine, thymine, cytosine, or guanine). These nucleotides are arranged in a double helix structure, with the nitrogenous bases pairing specifically (A with T, C with G) to form the rungs of the ladder.

Answer 4

DNA makeup is basically what makes it up, so, the DNA makeup is deoxyribose and nucleic acids.
