Question

Define the following:

Promoter

tRNA

Exons

​

Answer 1

Answer:

Promoter– The promoter serves as the binding site for RNA polymerase for transcription. It helps in transcription initiation.

tRNA– tRNA or transfer RNA is involved in the translation of proteins. It reads the genetic code on the RNA and transfers specific amino acids to mRNA on the ribosomes.

Exons– Exons are the coding regions present in a DNA sequence in eukaryotes.

Answer 2

Explanation:

Promoter is a region of DNA that helps in initiating the process of transcription. It serves as the binding site for RNA polymerase. tRNA or transfer RNA is a small RNA that reads the genetic code present on mRNA. ... Exons are coding sequences of DNA in eukaryotes that transcribe for proteins.
