Question

what molecule carries the genetic instructions from dna to ribosomes?
○ a. rrna (ribosomal rna)
○ b. mrna (messenger rna)
○ c. trna (transfer rna)
○ d. dna

Explanation:

• mRNA (Messenger RNA) is transcribed from DNA and carries the genetic instructions to ribosomes for protein synthesis.
• rRNA (Ribosomal RNA) is a component of ribosomes.
• tRNA (Transfer RNA) brings amino acids to the ribosome during protein synthesis.
• DNA stores genetic information but does not directly carry instructions to ribosomes.

Answer:

B. mRNA (Messenger RNA)
