Question

Which of the following statements correctly describes the universality of the genetic code?

Options

• The genetic code varies significantly within the same organism

• The genetic code is completely different in prokaryotes and eukaryotes

• The genetic code is unique to each individual organism

• The genetic code is nearly the same in prokaryotes and eukaryotes

Answer 1

Most of the genetic code is universal, meaning it is nearly identical across all organisms, from bacteria to humans. This universality suggests a common evolutionary origin for all life and allows for the transfer of genetic material between different organisms. However, some rare exceptions exist in certain organelles and organisms.
