If one strand of DNA has sequence ATCGTATG , the sequence in the complementary strand would be

Options

  1. ATAGCTTAC
  2. BTCACATAC
  3. CTAGCATAC
  4. DTACGATAC

Correct answer

C. TAGCATAC

Step-by-step solution

Due to size and geometries of bases, the only possible pairing in DNA are between G (guanine) and C (cytosine) through three H -bonds and between A (adenine) and T (thymine) through two H -bonds. Thus, the complementary strand of DNA will be
