A.
tRNA
B.
mRNA
AnswerC.
DNA
D.
rDNA
Answer: Option B
Solution
Answer: Option B
Solution:
The cDNA libraries can be prepared by isolating mRNA.The creation of a cDNA library starts with mRNA instead of DNA. Messenger RNA carries encoded information from DNA to ribosomes for translation into protein.
To create a cDNA library, these mRNA molecules are treated with the enzyme reverse transcriptase, which is used to make a DNA copy of an mRNA.
