Complementary DNA (cDNA) is

the same as the sense strand sequence of a gene the same as the antisense strand sequence of a gene mRNA reverse transcribed to DNA Correct a gene on the reverse strand

Complementary DNA (cDNA):
cDNA is synthetic DNA synthesized in vitro from a single-stranded mature messenger RNA (mRNA) template catalyzed by the enzyme reverse transcriptase (RNA-dependent DNA polymerase), followed by second-strand DNA synthesis.
Because mature eukaryotic mRNA has already undergone post-transcriptional splicing, cDNA contains strictly the continuous coding exons of genes without non-coding introns.
nalysis:
(mRNA reverse transcribed to DNA): Correct.

Correct option: (3) mRNA reverse transcribed to DNA
