Solution
(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.
