DNA MAKES RNA MAKES PROTEIN

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
One Codon = ____
A
1 protein
B
1 amino acid
C
1 RNA sequence
D
1 DNA strand
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: -One codon codes for only one amino acid. This is called (a) nature of genetic code. An exception to the above feature of genetic code is (b) codon. One of the salient features of genetic code Is codon is triplet and 61 codons code for amino acids and 3 codons are stop codons.

Detailed explanation-4: -Methionine and tryptophan are the only two amino acids that are coded for by just a single codon (AUG and UGG, respectively).
