Question
Biology Question on the molecular basis of inheritance
cDNA is
A
Formed by reverse transcriptase
B
Cloned DNA
C
Circular DNA
D
Recombinant DNA
Answer
Formed by reverse transcriptase
Explanation
Solution
Complementary DNA (cDNA) is formed on RNA template with the help of RNA dependent DNA polymerase called reverse transcriptase enzyme. The DNA is separated from the RNA-DNA complex in the presence of alkaline phosphatase enzyme. It is used as molecular probe.
