Question

A single strand of DNA helix has the code CGCTAA. Which would be the complementary code on the other strand of the helix? CGCAUU TATCGG ATAGCC GCGATT

Answer 1

the complimentary code on the other strand would be GCGATT,

A-adreninr combines with T-thymine

C-cytosine combines with G-guanine

Answer 2

Answer: The correct complementary code on the other strand of the helix is GCGATT.

According to Watson and Crick base pairing, in DNA-

• Adenine pairs with Thymine via two hydrogen bonds.
• Cytosine pairs with Guanine via three hydrogen bonds.

Thus, single strand of DNA with code CGCTAA will have the complementary code GCGATT
