c. Transcription, d. Translation
e. Codond

Text Solution

Verified by Experts

a. Gene: A gene is a sequence of base triplets in a strand of `DNA` helix that functions to code a polypeptide. Chain. The polypetide chain ultimately becomes the part of the protein synthesised. Every protein in a cell has the corresponding gene.
b. Genetic code: The relation between the amino acids and the nucleotide triplet is called genetic code.
c. Transcription : The way the code on `DNA` is copied to give the complementary code on `RNA` is called transcription.
d. Translation: The way the four-base code in nucleic acids is turned into a `20`unit code needed to specify the amino acid sequence in proteins during synthesis is called translation.
Codons: The nucleotide bases in `RNA` function in groups of three (triplets) in coding amino acids. these base triplets are called codons.
