Given the following DNA sequence (5' ( 3'), what would be the DNA sequence on the complementary strand (3' ( 5') of a double-stranded helix molecule? DNA sequence: AGTCCGA

Explanation: In the DNA, it is known that Adenine A (a purine) forms double bond only with Thymine T (a pyrimidine) and that Guanine G (a purine) forms triple bond only with Cytosine C (a pyrimidine). Thus, we will have:

DNA sequence 5' AGTCCGA 3'

Complimentary 3' TCAGGCT 5'

Complementary Base pair      - 3' TCAGGCT 5'

Explanation:

Chargaff's base pairing rule is used to determine the sequence of complementary strand of DNA

The base pair of puridine pair up with the base pair of pyrimidine

Pyrimidine - Adenine (A) and Guanine (G)

Puridine - Cytosine (C) and Thymine (T)

The base pairing rule is that adenine (A) always pairs with thymine (T)  and cytosine (C) always pairs with guanine (G)

Thus in a complementary DNA strand the complementing pair will be found

Given DNA sequence             - 5' AGTCCGA 3'

Complementary Base pair      - 3' TCAGGCT 5'
