Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which of the following is the start codon?
A
UAG
B
AUG
C
ATC
D
AUC
Explanation: 

Detailed explanation-1: -AUG, as the start codon, is in green and codes for methionine. The three stop codons are UAA, UAG, and UGA.

Detailed explanation-2: -The standard start codon for translation of a gene is “AUG, ” which encodes the amino acid methionine (Met or M), and establishes the reading frame for the ribosome to follow, adding corresponding amino acids in a polypeptide chain.

Detailed explanation-3: -ATG and AUG denote sequences of DNA and RNA respectively that are the start codon or initiation codon encoding the amino acid methionine (Met) in eukaryotes and a modified Met (fMet) in prokaryotes.

Detailed explanation-4: -Final Answer: AUG is the most starter codon.

Detailed explanation-5: -The standard start codon is AUG. The standard stop codon is UAG, UGA and UAA. Usually codes for methionine. It terminates the amino acid coding sequence.
