Question

Which of the following statements about genetic information is correct?
A) mRNA is the only type of RNA found in a eukaryotic cell
B) All forms of life employ the same genetic code
C) A typical human liver cell has one set of chromosomes
D) DNA is not found in prokaryotic cells

Accepted Answer

All forms of life, from simple bacteria to complex multicellular organisms like humans, use the same genetic code, which is a set of nucleotide triplets (codons) that specify which amino acid will be added next during protein synthesis. This universality supports the theory of common descent.
