How many letters or nitrogen bases make a codon in RNA?
A
1
B
2
C
3
D
6
Explanation: 

Detailed explanation-1: -Codons are made up of any triplet combination of the four nitrogenous bases adenine (A), guanine (G), cytosine (C), or uracil (U).

Detailed explanation-2: -In RNA, these bases are often labeled with the letters A, U, C, and G. A set of three bases makes up a codon. The messenger RNA contains many such codons, with a series of three bases followed by three more bases, and then three more bases, and so on.

Detailed explanation-3: -This sequence is broken into a series of three-nucleotide units known as codons (Figure 1). The three-letter nature of codons means that the four nucleotides found in mRNA-A, U, G, and C-can produce a total of 64 different combinations.

Detailed explanation-4: -A codon consists of 3 bases and there are 4 different kinds of bases in a nucleic acid altogether. There will be atotal of 43 = 64 codons. Q. A codon consists of 3 bases and there are 4 different kinds of bases in a nucleic acid altogether.

Detailed explanation-5: -Roughly in the middle of the tRNA molecule is a sequence of three bases called the anticodon. These three bases are hydrogen bonded to a complementary sequence in an RNA molecule-called messenger RNA, mRNA-during protein synthesis.
