Option D is correct
Explanation:
- Reverse transcriptase is an enzyme that use mRNA as a template to synthesize the DNA strand, this DNA is called cDNA. As gene is functional unit of DNA so gene is synthesized from mRNA by reverse transcriptase
- probe is a single stranded RNA or DNA sequences used to find out a complementary sequence in RNA or DNA
- cosmid is used as cloning vector to produce multiple copy of a particular gene.
- and the ligase is used to join or ligate two large molecule such as two DNA strands
- so, the option D is correct.
