Question
Consider the following segment in mRNA produced by the normal order of DNA nucleotides:
- CAU UCU CGA GUU -
(a) What is the amino acid order produced from this mRNA?
(b) What is the amino acid order if a mutation changes GUU to GGU?
(c) What is the amino acid order if a mutation changes CGA to UGA?
(d) What happens to protein synthesis if a mutation changes UCU to UGU?
(e) What happens if a G is added to the beginning of the mRNA segment?
(f) What happens if the C is removed from the beginning of the mRNA segment?
