Which is not true about the genetic code?AIt is exactly the same in all organismsBIt is composed of a tripletcode of three bases per codonCIt produces 64 different possibilities of base sequencesDIt contains start and stop codons as instructions

Dear stduent 

These codes help in the transformation of genetic information from one generation to another by the process of translation (Protein synthesis).
There are 64 different codons that were introduced to produce different amino acids. 
These codons are different for the different organism, no two organisms have the same codons as they may be deleterious.

So, the correct option is 'It is exactly the same in all organisms'.

The genetic code is the coding sequence which constitutes three base pairs called as codons. 
These codons are responsible for the formation of specific proteins. 
There are 64 different codons that were introduced to produce different amino acids. 
These codons are different for the different organism, no two organisms have the same codons as they may be deleterious.
These codes help in the transformation of genetic information from one generation to another by the process of translation (Protein synthesis).
Start codons are the initiation site of translation where protein synthesis occurs while stop codons are those bases which stops the process of formation of proteins and are called as termination codons.
So, the correct option is 'It is exactly the same in all organisms'.
