DNA MAKES RNA MAKES PROTEIN

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What are the three base segments of mRNA called?
A
anticodons
B
codons
C
triplets
Explanation: 

Detailed explanation-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. Of these 64 codons, 61 represent amino acids, and the remaining three represent stop signals, which trigger the end of protein synthesis.

Detailed explanation-2: -The mRNA bases are grouped into sets of three, called codons. Each codon has a complementary set of bases, called an anticodon.

Detailed explanation-3: -There are three termination codons that are employed at the end of a protein-coding sequence in mRNA: UAA, UAG, and UGA.

Detailed explanation-4: -DNA and the corresponding messenger RNA are made up of a series of bases. In RNA, these bases are often labeled with the letters A, U, C, and G. A set of three bases makes up a codon.
