Question

PLEASE ANSWER I HAVE 5 MINUTES

If a molecule of DNA has 32% guanine before DNA replication occurs, each new
molecule of DNA that is produced following replication will contain what percentage
thymine?

A) 64%
B) 32%
C) 18%
D) 36%

Answer 1

Answer:18%

Explanation:18x2=36 +64=100

Answer 2

If DNA molecule has 32% G (guanine) then it would have the same % of C (Cytidine) since G pairs with C in a double stranded DNA molecule, that would be the same during semi conservative replication.

Rest of it would be divided in A (adenine) or T (thymine).

GC content of DNA varies bases on organism and species and therefore, AT content varies as well.

Hope this helps (this is not my answer)
