Answer 1

Describe how nucleotides and hydrogen bonds affect the structure of DNA.

Answer 2

3 nucleotides (triplet code) code for a different amino acid, many of which codes for a protein, The different nucleotides are cytosine, Adenine, thymine and guanine. If a nucleotide was replaced by a different one, it would cause a different amino acid to be produced, and therefore a different protein. Adenine and rhyming bond together with 2 hydrogen bonds, and guanine and cytosine have 3 hydrogen bonds

Answer 3

The nucleotides are like the 'rungs of the ladder' of the helix shape
