Answer :
Relations will be found in the percentages of bases of a double‑stranded DNA molecule is :
A+G=T+C
(A+G)/(C+T) =1.0
A/T=G/C
- A double helix is the form that two strands of the macromolecule DNA take when they twist around a shared axis. The nitrogenous base pairs that make up the base pairs on the rungs and the alternating sugar and phosphate groups that make up the sides of the ladder give the double helix its ladder-like appearance.
- DNA molecules can be hundreds of thousands to millions of base pairs long. Chromosome 21, the smallest chromosome in the human genome, with around 48 million base pairs.
- A DNA molecule's double helix is composed of nitrogenous bases that are arranged in a certain way on each of its two strands. Cytosine partners with guanine, whereas adenine pairs with thymine.
