In a nucleotide, which would change based on the genetic code of the organism?

deoxyribose
nucleotide
phosphate
nitrogen base

The correct answer is nitrogen base

Explanation:

The nucleotide sequence of one codon differ from that of another codon by the presence or absence of specific nitrogen base.The nucleotide sequence of different codons contain different nitrogen bases.

       As a result change in genetic code result from the change in the nitrogen bases of the codons present in the genetic code.

  In simple words change in single nitrogen base of a codon will change the entire codon.

answer; the above answer to the above statement is (true)

if your own plato the answer is b. the fern transitioned from sporophyte generation to gametophyte generation.
