In bacteria, the codon AUG stands for
A)Glycine
B)Methionine
C)N-formyl methionine
D)Both B and C

Explanation

Solution

Prokaryote genomes shows a wide scope of GC substance and codon utilizes, both coming about due to the reason of communication between mutational predisposition and characteristic choice.This is a codon that is required to the amino acid methionine, which is almost consistently the major amino acid in a polypeptide chain.

Complete answer:
The cycle of translation i.e protein amalgamation is composed of three cycles initiation, elongation, and termination.
The amalgamation of all proteins usually starts with a similar amino corrosive: methionine. In eubacteria, the main and major amino acid in a soon orchestrated polypeptide is N-formyl methionine.

Anyway, formylation is not essential on the grounds that non-formylated methionine can work as an initiator amino acid.
Eukaryotes and archaea additionally utilise methionine as a beginning amino acid, however, it isn't formylated methionine.
In eubacteria, for instance, E.coli, AUG, and GUG and on uncommon events. UUG fill in as commencement codons.

At the point when one of these trios is found in the inception position, it is processed by N-formyl Mett-RNA and N-formylmethionine shows in the form of the main amino acid in the chain.

The significance of AUG and GUG codons is dependent upon their unique circumstance. At the point when the AUG codon is used for inception, it is perused as formyl-methionine; when used inside the coding district, it communicates to methionine.

Additionally, when GUG codon covers in such a way as a commencement codon, it is perused as formylmethionine. Commencement in the eukaryotic cytoplasm usually uses AUG as the initiator.

Hence, the correct answer is option (C)

Note: The translation is termed as a cycle by which the hereditary code present inside a courier RNA (mRNA) particle is decoded to produce a particular arrangement of amino acids in a polypeptide chain. For translation to take place, the beginning codon 5'AUG must be perceived.
