Which RNA carries genetic information from DNA to the ribosome to specify amino acid sequence?

Explanation:
Messenger RNA carries the genetic message from DNA to the ribosome so the amino acid sequence of a protein can be built. It’s produced by transcription, creating a template that ribosomes read during translation. The ribosome deciphers the codons on mRNA, and transfer RNA brings the appropriate amino acids to add to the growing chain. Ribosomal RNA makes up the ribosome itself and helps catalyze peptide bond formation, while microRNA typically regulates gene expression rather than encoding amino acids. So the molecule that conveys the information needed to specify the protein’s sequence is messenger RNA.
