Biology Question on Molecular Basis of Inheritance
Explain(in one or two lines)the function of the followings:
(a)Promoter
(b)tRNA
(c)Exons
Answer
(a) Promoter Promoter is a region of DNA that helps in initiating the process of transcription. It serves as the binding site for RNA polymerase.
(b) tRNA tRNA or transfer RNA is a small RNA that reads the genetic code present on mRNA. It carries specific amino acid to mRNA on ribosome during translation of proteins.
(c) Exons Exons are coding sequences of DNA in eukaryotes that transcribe for proteins.
