Which of the Following is Used to Make Complementary DNA

Question

Which of the following is used to make complementary DNA (cDNA)from RNA?
A) restriction enzymes
B) gene cloning
C) DNA ligase
D) gel electrophoresis
E) reverse transcriptase

Accepted Answer

Reverse transcriptase is an enzyme that is used to make cDNA from RNA, by catalyzing the reverse transcription reaction. This process involves using RNA as a template to make a complementary DNA strand, which can then be used for further analysis or manipulation. Reverse transcriptase is commonly used in research and biotechnology applications, such as gene expression analysis and recombinant DNA technology. The other options listed (A, B, C, and D) are not involved in the process of making cDNA from RNA.
