Which molecule carries information from DNA to a ribosome?

Which molecule carries information from DNA to a ribosome?

• A. RNA polymerase
• B. Heredity
• C. mRNA
• D. Codon/Triplet

Answer: (C)

Genetic information flows from DNA to the ribosome through messenger RNA. The mRNA is produced by transcription, copying the DNA sequence into an RNA strand that can travel to the ribosome and be read in sets of three nucleotides called codons. Each codon specifies a particular amino acid to be added to the growing protein, with tRNA delivering the amino acids accordingly. RNA polymerase is the enzyme that builds the RNA from DNA, but it is not the information carrier itself. Codon or triplet refers to those three-nucleotide units on the mRNA that encode amino acids, not the molecule that transports the information. Heredity is the general concept of passing traits, not a molecule.
