Answer:
GCCGAAT
Step-by-step explanation:
Deoxyribonucleic acid, also known as DNA, is a molecule that serves as the genetic material in living organisms. It is a double-stranded molecule made up of nucleotides subunits. The nucleotides, which are Adenine (A), Guanine (G), Cytosine (C) and Thymine (T) on each strand are held together using the COMPLEMENTARY BASE PAIRING RULE.
The complementary base pairing rule states that an Adenine base will always hydrogen bond with Thymine base while Guanine will always bond with Cytosine base i.e. A-T, G-C. Based on the rule, a DNA strand with sequence: CGGCTTA will have a complementary sequence of GCCGAAT on the other strand.
