Question
please please explain stepwise
21.78 Consider the following segment of mRNA produced by the normal order of DNA nucleotides 5'CUU AAA CGA GUU 3' a What is the amino acid order produced from this mRNA? b. What is the amino acid order if a point mutation changes CUU to CCU C. What is the amino acid order if a point mutation changes CGA to AGA? d What happens to protein synthesis if a point mutation changes AAA to UAA? e. What is the amino acid order if an insertion mutation adds a G to the beginning of the mRNA segment? f. What is the amino acid order if a deletion mutation removes the C at the beginning of the mRNA segment?Explanation / Answer
AS PER CHEGG POLICY, PROCEEDING TO ANSWER A MINIMUM OF FIRST 4 QUESTIONS / SUB-QUESTIONS / PARTS / SUBPARTS, THAT IS QUESTIONS 21.78(a) to 21.78(d):
ANSWER 21.78
5' - CUU AAA CGA GUU - 3'
Answer a.
Using the codon table, each 3-letter mRNA codon encodes an amino acid, we get:
LeuLysArgVal
Answer b.
When CUU becomes CCU, we get:
5' - CCU AAA CGA GUU - 3'
Using the codon table, each 3-letter mRNA codon encodes an amino acid, we get:
ProLysArgVal
Answer c.
When CGA becomes AGA, we get:
5' - CUU AAA AGA GUU - 3'
Using the codon table, each 3-letter mRNA codon encodes an amino acid, we get:
LeuLysArgVal
Answer d.
When AAA becomes UAA, we get:
5' - CUU UAA CGA GUU - 3'
Using the codon table, each 3-letter mRNA codon encodes an amino acid, we get:
Leu(followed by Stop Codon so protein synthesis stops)
