Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
How many codons equals 1 amino acid?
A
1
B
2
C
3
D
4
Explanation: 

Detailed explanation-1: -Each codon corresponds to a single amino acid (or stop signal), and the full set of codons is called the genetic code. The genetic code includes 64 possible permutations, or combinations, of three-letter nucleotide sequences that can be made from the four nucleotides.

Detailed explanation-2: -Answer and Explanation: tRNA read RNA nucleotides in a triplet. One codon corresponds to three nucleotides. One codon translates to one amino acid.

Detailed explanation-3: -Group I amino acids are glycine, alanine, valine, leucine, isoleucine, proline, phenylalanine, methionine, and tryptophan. The R groups of these amino acids have either aliphatic or aromatic groups. This makes them hydrophobic (“water fearing”).

Detailed explanation-4: -Three codons are needed to specify three amino acids. Codons can be described as messengers that are located on the messenger RNA (mRNA). It is a sequence of three nucleotides that code for one specific amino acid; therefore, every three nucleotides represent one codon.

Detailed explanation-5: -Hidden within the genetic code lies the “triplet code, ” a series of three nucleotides that determine a single amino acid.
