The statement that provides evidence of the common ancestry of all life is near universality of the genetic code (option A).
<h3>What is the genetic code?</h3>
Genetic code is the set of rules by which the sequence of bases in DNA are translated into the amino acid sequence of proteins.
The genetic code has the following characteristics:
- The genetic code is universal i.e all known living organisms use the same genetic code.
- The genetic code is unambiguous i.e. each codon codes for just one amino acid (or start or stop)
- The genetic code is redundant i.e. most amino acids are encoded by more than one codon.
Therefore, the statement that provides evidence of the common ancestry of all life is near universality of the genetic code.
