Question

multiple choice question
which type of rna is correctly described?

ribosomal rna - carries the genetic code from dna to produce an amino acid chain
transfer rna - brings amino acids to the site of protein synthesis
messenger rna - binds with proteins to form the ribosome

Explanation:

• Ribosomal RNA (rRNA) combines with proteins to form ribosomes, not carry genetic code from DNA. So the first option is incorrect.
• Transfer RNA (tRNA) functions to bring amino acids to the ribosome (site of protein synthesis) during translation. This description is correct.
• Messenger RNA (mRNA) carries the genetic code from DNA to the ribosome to direct amino acid chain synthesis, not bind with proteins to form ribosomes (that's rRNA). So the third option is incorrect.

Answer:

B. Transfer RNA - Brings amino acids to the site of protein synthesis
