Question

Suppose there is a strand of DNA that has the following sequence on one strand: ATTCAGGC. What is the sequence of bases on the matching strand?

Answer 1

1) DNA is where all the genetic information of the cells and the organism is stored, it is made up of nucleotides Adenine, Guanine, Cytosine, and Thymine. Two purines ( A, G) and two pyrimidines (T, C). One purine binds with its complementary pyrimidine with hydrogen bonds. So A-T, C-G always bind with each other. This is a hard and fast rule. They both have nitrogenous bases which complementarily bind with each other.

Adenine is a purine (C5H4N4) and Thymine is a pyrimidine (aromatic ring with nitrogenous base, forms hydrogen bonds with adenine).

Using this principle the parallel sequence then becomes

TAAGTCCG.
