Question

part of dna molecule that varies among dna

Answer 1

A single nucleotide is made up of three components: a nitrogen-containing base, a five-carbon sugar, and a phosphate group. ... The five-carbon sugar is either a ribose (in RNA) or a deoxyribose (in DNA) molecule

Answer 2

Answer:

1. DNA or Deoxy Ribonucleic Acid, are the units which are the "main component" of the genes, that are our hereditary units.

2. DNA is made up of double helical strands, having a pentose sugar phosphate backbone, nitrogenous bases, and hydrogen bond that bonds with these nitrogenous bases.

3. It is the "four nitrogenous bases", Adenine, Thymine, Guanine and Cytosine that varies among the DNA.

4. Adenine always binds with Thymine, forming a "double hydrogen bond".

5. Guanine always binds with Cytosine, forming a "triple hydrogen bond".
