Question

Use the following DNA sequence information to answer questions 11 and 12: Assume that the following DNA is transcribed from left to right. 5' -ATGTACTAAGCCGTAGCGTAA-3' 3' -TA CATGATTCGGCATCGCATT-5' What is the sequence of the template strand of DNA? (a) 5'-TACATGTAAGCCGTAGCGCAA-3' (b) 3' -ACGCGATAACGACTGTACATA-5' (c) 5'-ATGTACTCAGCCGTAGCGTAA-3' (d) 5'-TACATGATTCGGCATCGCATT -5' (e) 3'-TACATGATTCGGCATCGCATT-5' 12. Translate the RNA sequence to amino acid sequence using the following table: which amino acid sequence is correct? (a) Met-Tyr-Val-Ala-Ser-Ala-Stop (b) Met-Tyr-Ser-Ala-Val-Ala-Leu (c) Met-Tyr-Stop (d) Leu-Arg-Tyr-Gly-Stop (e) Met-Tyr-Tyr-Ala-Val-Ala-Stop

Explanation / Answer

11. E

3'TACATGATT....

Reason: template stand is in 3-->5' direction and ayntheises RNA in 5"--> 3' direction.

12. C

Met- Tyr- stop

Reason:

mRNA sequence

5' AUG UAC UAA GCC UAG CGU AA 3'

AUG= met

UAC = Tyr

UAA= Stop
