Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The genetic code is essentially the same for all organisms. From this, one can logically assume which of the following?
A
The same codons in different organisms translate into the different amino acids.
B
A gene from an organism can theoretically be expressed by any other organism.
C
All organisms have experienced convergent evolution.
D
DNA was the first genetic material.
Explanation: 

Detailed explanation-1: -So, the correct option is ‘All organisms share a genetic code organized into triplet codons, making it possible for one organism to express a gene from any other organism. ‘

Detailed explanation-2: -The universal triple-nucleotide genetic code, allowing DNA-encoded mRNA to be translated into the amino acid sequences of proteins using transfer RNAs (tRNAs) and many accessory and modification factors, is essentially common to all living organisms on Earth (1, –3).

Detailed explanation-3: -In all living organisms, the instructions for reproducing and operating the individual is encoded in a chemical language with four letters–A, C, T, and G, the initials of four chemicals. Combinations of three of these letters specify each of the amino acids that the cell uses in building proteins.
