Most organisms contain the same codons. true false

True

Explanation:

All living organisms store their genetic information using the same molecules (DNA and RNA). The information encoded by these molecules needs to be decoded through gene expression and the way in which it is done is through the GENETIC CODE, which comprises of all the codons that encodes an amino acid.

There are only 20 common amino acids in proteins. These amino acids are specified by a group of three nucleotides in the DNA/RNA molecule, called CODONS. Each of these codons specifies an amino acid, although more than one codon can encode a particular amino acid, since there are 64 possible codons that can encode these 20 amino acids (more than enough).

One of the characteristics of the genetic code is its universality i.e. The same genetic code is employed by every known living organism with little or no exceptions.

The same codon specifies the same amino acid in most known living organisms. A codon does not code for a different amino acid in another organism. It is universal that codon AUG codes for Methionine in most living organisms.

This same coding in all organisms is a convincing evidence that all organisms share a common evolutionary history.
