Vedclass · Answer

(B) The term $cDNA$ stands for complementary $DNA$,which is synthesized from mature $mRNA$ using the enzyme reverse transcriptase.Mature $mRNA$ has already undergone the process of splicing,during which all non-coding sequences known as introns are removed.Since $cDNA$ is synthesized from this processed $mRNA$ template,it contains only exons and lacks any introns.Therefore,the number of introns present in $cDNA$ is $0$.

If there are $81$ million bases in the $RNA$ of a human cell,calculate the total number of introns present in $cDNA$.
