genetic material Flashcards
1
Q
Suggest one advantage of showing the genetic code as base sequences on mRNA, rather than triplets on DNA.
A
ribosomes assemble polypeptides using mRNA code
OR
DNA has two strands each with a different (complementary) base sequence
2
Q
What name is given to a group of three bases on mRNA that codes for an amino acid?
A
Codon
3
Q
suggest the role of the mRNA base triplets UGA, UAG and UAA. of stop codons
A
Stop translation;
- Result in detachment of polypeptide chain from ribosome
