. A double-stranded DNA molecule with the sequence shown hereproduces, in vivo, a polypeptide that is five amino acids long. TACATG ATC ATT TCA CGG AAT TTC TAG CAT GTA ATG TAC TAG TAA AGT GCC TTAAAG ATC GTA CAT a. Which strand of DNA is transcribed and in whichdirection? Support your response by indicating the 5 amino acidsequence that results when this transcript is translated. (2 pts)b. Label the 5’ and the 3’ ends of each strand in the original DNAmolecule. (1 pt) c. If an inversion occurs between the second andthird triplets, from the left and right ends, respectively, and thesame strand of DNA is transcribed, how long will the resultantpolypeptide be and what is its sequence? (Hint: rewrite the DNAmolecule AFTER the inversion.) (3 pts) d. Assume that the originalmolecule is intact and that the bottom strand is transcribed fromleft to right. Give the base sequence, and label the 5’ and 3’ endsof the anticodon that inserts the fourth amino acid into thenascent polypeptide. What is this amino acid?
