Question

Which of the following can be inferred from the genetic code?

A.All organisms have a common biochemical evolutionary origin.

B.Organisms can live without genetic code.

C.Four nucleotides.

D.Four nucleosides.

Answer 1

A. All organisms have a common biochemical evolutionary origin.

Step-by-step explanation:

Genetic code is the biological mechanism by which the DNA in our body is used to synthesize protein needed for growth and development. The genetic code comprises of all the possible 64 codons i.e. a group of three nucleotides that encode an amino acid.

One of the characteristics of the genetic code is that it is UNIVERSAL. This means that all known living organisms make use of the same genetic code and hence, this portrays that all living organisms share a common biochemical evolutionary origin.
