Question

How do you relate amino acids R group to a neucltide's neutrogenous base

Answer 1

Welcome to OpenStudy, http://en.wikipedia.org/wiki/Nucleotide <- this link should help you.

Answer 2

DNA sequence is determined by its nucleotide sequence. A nucleotide is composed of a phosphate group , deoxy sugar and a nitrogenous base. All the nucleotides in a DNA contain the same phosphate and deoxy-sugar but have different nitrogenous bases , so it is actually the nitrogenous base that determines the DNA sequence.

Similarly the amino acid sequence of a protein is determined by the R group , as all the amino acids have the same NH2 , COOH and H attached to the C atom but a different R group. Hence this way you can relate the nitrogenous base of nucleotides in DNA to the R group of amino acids in protein. Both determine the sequence of the respective biomolecules of which they are constituents of.
