If one side of DNA molecule had a base sequence of adenine-adenine-guanine-cytosine-thymine-cytosine-thymine, what would the sequence of bases on the opposite side of the molecule be?

Expert Solution
Step 1

 DNA or deoxyribonucleic acid, the major genetic material, is a polynucleotide chain made of monomeric units of nucleic acids. Nucleic acids are made up of three components:

  • A base that has a nitrogen atom.
  • A 5-C sugar
  • An ion of phosphoric acid

   According to the Watson-Crick double helix model of DNA, B-form of DNA has two long polynucleotide strands coiled around a central axis. The strands are wrapped plectonemically in a right handed helix. The two strands are antiparallel and they interact by hydrogen bonds between complementary nucleotide base pairs.

  • Guanine (G) forms three hydrogen bonds with Cytosine (C).
  • Adenine (A) forms two hydrogen bonds with Thymine (T).
