Question at position 72 True or False. The genetic code in bacteria is different from the genetic code in humans.TrueFalse

BlackTom AI · Accepted Answer

The question asks whether the genetic code in bacteria is different from the genetic code in humans.
Option 1: True. This would claim that bacterial and human genetic codes are fundamentally different. In most organisms, including bacteria and humans, the codon table used to translate mRNA into amino acids is the same, so this statement is generally inaccurate. There are special cases where certain codons are reassigned or mitochondria use a variant code, but these are exceptions rather than the rule for bacteria vs humans as a whole.
Option 2: False. This choice aligns with the broad principle of the genetic code being universal across most life, meaning the same codons specify the same amino acids in both bacteria and humans. The universal code is a foundational concept in molecular biology, and while there are noted deviations in organelles like mitochondria or some specialized organisms, the standard code used in bacteria and humans is effectively the same for the vast majority of genes and organisms. Misconceptions often arise from conflating the universal code with these known exceptions, or from confusing codon usage with codon meaning.
In summary, asserting a different genetic code between bacteria and humans ignores the overarching universality of the standard genetic code, acknowledging only limited, well-documented exceptions rather than a wholesale difference.
