Vedclass · Answer

(A) The Assertion is correct because $cDNA$ (complementary $DNA$) libraries are essential in human genomics as they represent only the expressed genes (exons) of an organism,excluding introns.The Reason is also correct because $cDNA$ is synthesized in the laboratory using the enzyme reverse transcriptase,which uses $mRNA$ as a template to create a $DNA$ strand.Since $cDNA$ libraries provide a snapshot of the transcriptome (expressed genes),they are highly valuable for identifying genes and studying gene expression,which directly supports the Assertion. Therefore,the Reason is the correct explanation of the Assertion.

$(a)$ Bacillus thuringiensis	$(i)$ Cloning vector
$(b)$ Thermus aquaticus	$(ii)$ Construction of first rDNA molecule
$(c)$ Agrobacterium tumefaciens	$(iii)$ $DNA$ polymerase
$(d)$ Salmonella typhimurium	$(iv)$ Cry proteins

$A$: $cDNA$ libraries are important to scientists in human genomics.
$R$: $cDNA$ is a synthetic type of $DNA$ generated from $mRNA$.
