If the sequence of one strand of DNA is ATGCTC, the sequence of the other strand would be :
Correct answer: C. TACGAG
- A. CACGTC
- B. TAGCATG
- C. TACGAG
- D. GACGTG
Explanation
In DNA, the base pairs are complementary to each other. Adenine (A) always pairs with thymine (T), and guanine (G) always pairs with cytosine (C). Therefore, if one strand of DNA has the sequence ATGCTC, the other strand will have the complementary sequence i.e., TACGAG.

About Structure of DNA
DNA structure includes nucleotides made of deoxyribose, phosphate and nitrogenous bases, arranged in two antiparallel polynucleotide strands. Questions cover the double helix, phosphodiester and hydrogen bonds, complementary base pairing between adenine and thymine and between guanine and cytosine, and the significance of major and minor grooves.
