In this DNA sequence: 5'-TCGTATAATGTGAGACATCCCTATTAGCGCCATCTACATGTTACTTGCC-3'

a. Underline the TATA box.

b. Underline the initiation codon.

c. What would the third amino acid be if a cytosine were inserted right after the initiation codon?

Please provide explanation and not just correct answers.

Answer #1

a. Underline the TATA box. (TATAAT is the sequence of TATA box, so the answer is )

5'-TCGTATAATGTGAGACATCCCTATTAGCGCCAATGTTACTTGCC-3'

b. Underline the initiation codon.(The codon which codes for methionine is the strting codon. So, the DNA seq is TAC. So the answer is )

5'-TCGTATAATGTGAGACATCCCTATTAGCGCCATCTACATGTTACTTGCC-3'

c. What would the third amino acid be if a cytosine were inserted right after the initiation codon?

Please provide explanation and not just correct answers. (These type of mutations is called as frameshift muation, so the answer is )

Before insertion: TAC ATG TTA - MET - TYR - ASN

AFTER INSERTION : TAC CAT GTT - MET - VAL -GLN
