The genetic code is essentially the same for all organisms. From this, one can logically assume which of the following?
A) A gene from an organism can theoretically be expressed by any other organism.
B) All organisms have experienced convergent evolution.
C) DNA was the first genetic material.
D) The same codons in different organisms translate into different amino acids.
E) Different organisms have different types of amino acids.

Quizplus · Accepted Answer

If the genetic code is the same, it means that the nucleotide sequence for a given gene (and its corresponding mRNA sequence) is the same across different organisms. This means that a gene from one organism could potentially be expressed by another organism, as long as the necessary machinery for transcription and translation is present. This has been experimentally demonstrated through genetic engineering techniques, where genes from one organism are inserted into another and expressed successfully. Therefore, option A is the best choice.
