Question

Which of the following would be synthesized using 5′-CAGTTCGGA-3′ as a template?

3′-AGGCTTGAC-4′
3′-TCCGAACTG-5′
3′-GTCAAGCCT-5′
3′-CAGTTCGGA-5′

Answer 1

Option C, 3′-GTCAAGCCT-5′

Step-by-step explanation:

The template used for replication synthesizes amino acids with

a) reverse head and tail ends - which means the 5' end will pair up up with the 3' end of the amino acid synthesized by the given template like wise 3' will pair up up with the 5' end of the synthesized amino acid.

b) The pairing of template occurs as per the rule of base pair in which

adenine (A) pair up with thymine (T) and guanine (G) pair up with cytosine(C).

Thus given template 5'-CAGTTCGGA-3' will

synthesise 3′-GTCAAGCCT-5′

Hence, option C is correct
