Question

What does the start codon code for in bacteria?

Answer 1

Codon:

1. A sequence of three consecutive nucleotides in a DNA or RNA molecule that codes for a specific amino acid are known as a codon.
2. Ribosomes start to read codons that are present on mRNA, starting with AUG codon, that code for amino acid methionine.
3. Start codon will make a reading frame by adding corresponding amino acids in a polypeptide chain.
4. The start codon always codes for methionine in eukaryotes and an N-formylmethionine (fMet) in bacteria.
