Question

What complementary strand of DNA would be produced from the strand of DNA shown below? CGT AT A. GCT AT B. CGT AT C. CGA TA D. GCA TA

Answer 1

D should be the answer! :)

Answer 2

Answer: Option (D) is the correct answer.

Step-by-step explanation:

Shape of DNA molecule is like a twisted ladder. This structure of DNA is solved by James Watson and Francis Crick.

According to Watson and Crick base pairing:

• A (Adenine) pairs with T (Thymine) with the help of two hydrogen bonds.
• G (Guanine) pairs with C (Cytosine) with the help of three hydrogen bonds.

Thus, given strand of DNA is CGTAT and its complementary strand will be GCATA.
