Question

A codon a. consists of discrete amino acid regions. b. consists of two nucleotides. c. is found in all eukaryotes, but not in prokaryotes. d. catalyzes RNA synthesis. e. may code for the same amino acid as another codon.

Answer 1

Answer: The correct answer is option e.

Explanation:

A codon refer to the sequence of three nucleotide in DNA or RNA which is also termed as unit of genetic code.

It is present in both prokaryotic as well as eukaryotic cells.

A codon codes for specific amino acid. It does not catalyze any reaction.

There are 64 universal codons; however, only 20 amino acids. It is the reason that many codons may code for single amino acid.

For example, UUU and UUC code for phenylalanine, AUU, AUC, and AUA code for isoleucine, et cetera.

Answer 2

The statement which is true of a codon is that: E. may code for the same amino acid as another codon.

What is a codon?

A codon can be defined as a sequence of three (3) consecutive nucleotides which acts as a genetic unit of life and it is used as a template for the amino acid synthesis that is required for protein expression in living organisms.

Generally, the two main characteristics of a codon include the following:

• It can code for the same amino acid as another codon.

• It can not code for more than one amino acid.
