Answer:
This question lacks options, the options are as follows:
A. 3’ ATA GTG CCC AAC GGT 5’
B. 3’ TAT CAA GGG TTG CCA 5’
C. 3’ TAT CAC GGG TTG CCA 5’
D. 3’ TAT CAC GGG TTG CCT 5’
The answer is C
Explanation:
DNA replication is the process by which a DNA molecule makes a copy of itself i.e. duplicated. In this process, the double-stranded DNA molecule splits into two single strands, which each serves as template for the synthesis of another strand. The new strand is synthesized using the COMPLEMENTARY BASE PAIRING RULE.
Complementary base pairing rule states that an Adenine base will always hydrogen bond with a Thymine base while Guanine base will always hydrogen bond with Cytosine base i.e. A-T, G-C. Hence, given the original strand of DNA in this question, the complementary strand will have the following sequence: 3’ TAT CAC GGG TTG CCA 5’
