PLEASE HELP
which statement best compares the base sequence of an mRNA molecule with that of the cDNA made from the mRNA
a. they are equal
b. they are opposite
c. they are parallel
d. they are complementary

Respuesta :

Answer:

The correct answer will be option D (they are complementary).

Explanation:

Complementary DNA or cDNA is an edited DNA molecule synthesized from a single-stranded RNA called mRNA. The reaction of cDNA formation from mRNA is catalyzed by an enzyme called "reverse transcriptase".

The cDNA strands formed is also known as a complementary copy of mRNA as it contains no introns or non-coding sequence in its sequence similar to mRNA. cDNA is used in recombinant DNA technology to clone eukaryotic genes in prokaryotes.

Thus, option D (they are complementary) is the correct answer.
