The same codons in different organisms translate into the different amino acids.
|
|
|
A gene from an organism can theoretically be expressed by any other organism.
|
|
|
All organisms have experienced convergent evolution.
|
|
|
DNA was the first genetic material.

Detailed explanation-1: -The genetic code is essentially the same for all organisms. From this, one can logically assume which of the following? A gene from an organism can theoretically be expressed by any other organism.
Detailed explanation-2: -All known living organisms use the same genetic code. This shows that all organisms share a common evolutionary history. The genetic code is unambiguous. Each codon codes for just one amino acid (or start or stop).
Detailed explanation-3: -A gene from an organism can theoretically be expressed by any other organism. All organisms have experienced convergent evolution. DNA was the first genetic material. The same codons in different organisms translate into the different amino acids.
Detailed explanation-4: -Because most of the 20 amino acids are coded for by more than one codon, the code is called degenerate. The genetic code, once thought to be identical in all forms of life, has been found to diverge slightly in certain organisms and in the mitochondria of some eukaryotes.
