In the context of creating cDNA libraries, what is the template used for synthesis?
A
tRNA
B
mRNA
C
DNA
D
rRNA
Verified step by step guidance1
Understand the concept of cDNA libraries: cDNA libraries are collections of complementary DNA (cDNA) sequences that are synthesized from messenger RNA (mRNA) templates. They are used to study gene expression and function.
Identify the role of mRNA: mRNA serves as the template for cDNA synthesis because it represents the expressed genes in a cell. This allows researchers to focus on the coding regions of the genome.
Differentiate between mRNA and other types of RNA: mRNA is distinct from tRNA and rRNA, which are involved in protein synthesis but do not carry the coding information for proteins. Therefore, they are not used as templates for cDNA synthesis.
Recognize the process of reverse transcription: In cDNA library creation, reverse transcriptase is used to convert mRNA into cDNA. This enzyme synthesizes a DNA strand complementary to the mRNA template.
Conclude the correct template: Based on the understanding of cDNA library creation, mRNA is the correct template used for synthesis, as it provides the necessary coding information for generating cDNA.
