Eukaryotic Gene Expression Problem Set

Problem 9: Hybridization of mRNA with the DNA coding strand

mRNA will form hybrids only with the coding strand of DNA because:

A. DNA will not reanneal at high temperatures

B. the salt concentration will affect DNA reannealing

C. DNA will not reanneal at low temperatures

D. RNA:DNA hybridization follows the base-pairing rules
An RNA molecule can form a base-paired DNA-RNA duplex molecule with a DNA that has complementary base pairing.

E. denatured DNA will not reanneal after it is diluted
