nucleic acids

Question 1

Explain the function of the genetic code

Answer 1

DNA code is copied as mRNA / transcription;

mRNA undergoes translation;

on ribosome;

produces proteins / polypeptides

Question 2

Explain the consequence of a reduction in the transcription of the genes that naturally stop tumours from forming.

Answer 2

mRNA copy of gene not formed;

so no translation;

into protein;

proteins not present to prevent tumours forming

Question 3

what are the features of the genetic code

Answer 3

degenerate ✔
(because) idea that there is more than one
codon for (most) amino acids ✔

triplet (code) ✔
(because) idea that three bases are
needed to code for one amino acid ✔

non-overlapping ✔
idea that the sequence is read so that each
base is only part of one , codon / triplet ✔
