A template strand of DNA contains nucleotides in the following proportions: 14% adenine
MAXImum [283]

Answer:

The proportions of  nucleotides in the newly formed complimentary strand will be:

14% Thymine (T), 33% Adenine (A), 21% Guanine (G), 32% Cytosine (C).

Explanation:

In a double stranded DNA, the nucleotides of one strand binds with nucleotides of another strand through hydrogen bonds.

Adenine binds with thymine by two hydrogen bonds (A=T) and guanine binds with cytosine by three hydrogen bonds (G≡C).

So, the complimentary strand must have

  • thymine equal to the amount of adenine in template strand.
  • adenine equal to the amount of thymine in template strand.
  • guanine equal to the amount of cytosine in template strand.
  • cytosine equal to the amount of guanine in template strand.
