In the context of organic chemistry, what is a cDNA molecule?
A
A DNA molecule that contains a sequence of amino acids
B
A synthetic polymer used in the production of plastics
C
A type of RNA molecule that carries genetic information from DNA to the ribosome
D
A complementary DNA molecule synthesized from an mRNA template
Verified step by step guidance1
Understand that cDNA stands for complementary DNA, which is a DNA molecule synthesized from an mRNA template.
Recognize that cDNA is not a sequence of amino acids, as DNA and RNA are nucleic acids, not proteins.
Note that cDNA is not a synthetic polymer used in plastics; it is a biological molecule used in genetic studies.
Remember that cDNA is not a type of RNA; it is DNA synthesized from RNA, specifically mRNA, using the enzyme reverse transcriptase.
Conclude that the correct description of a cDNA molecule is a complementary DNA molecule synthesized from an mRNA template, often used in gene cloning and expression studies.
