To answer the following questions refer to the four items listed below.
-This is any DNA made from mRNA transcripts.
A)cDNA
B)Restriction enzymes
C)Reverse transcriptase
D)DNA library

Question

Quizplus · Accepted Answer

cDNA stands for complementary DNA, it is synthesized from single-stranded RNA (mRNA) in a reaction catalyzed by the enzyme reverse transcriptase. This process can be used to create a DNA library containing genes expressed in a particular cell or tissue.

Answer: C 
 Reverse transcriptase is an enzyme that can synthesize a complementary DNA strand from an RNA template. This process is commonly used in molecular biology to create cDNA libraries or to study the expression of genes via reverse transcriptase-PCR (RT-PCR).

Answer: D 
 A DNA library is a collection of DNA fragments derived from a particular organism, tissue, or cell type. These libraries can be used to identify and isolate specific genes of interest, or to study the overall genetic makeup of a given organism or tissue.

B) Restriction enzymes are not related to the production of cDNA or DNA libraries, they are used to cut and manipulate DNA for various molecular biology techniques.
