Amino acids are delivered to the ribosome by

A.

mRNA

B.

rRNA

C.

tRNA

D.

micRNA

Answer and Explanation

The Correct Answer is C

A. mRNA: Messenger RNA provides the codon template that dictates amino acid sequence but does not physically deliver amino acids.

B. rRNA: Ribosomal RNA is part of the ribosome’s structural and catalytic core and assists in peptide bond formation, but it does not carry individual amino acids.

C. tRNA: Transfer RNA molecules carry specific amino acids to the ribosome and match their anticodon to mRNA codons, delivering the correct amino acids for incorporation into the growing polypeptide.

D. micRNA: MicroRNA (miRNA) are small regulatory RNAs involved in gene expression control, not carriers of amino acids to ribosomes.

Correct Answer is B

Explanation

B. False: Endospores are highly resistant to heat and other stresses; because microwaves can heat unevenly and may not achieve sterilizing conditions, reheating food in a microwave does not reliably kill bacterial endospores.

Correct Answer is D

Explanation

A. DNA replication: DNA replication copies DNA from a DNA template and does not use RNA as the template for making DNA.

B. Transcription: Transcription is the synthesis of RNA from a DNA template, not the synthesis of DNA from RNA.

C. Translation: Translation converts mRNA codons into amino acids to build proteins; it does not produce DNA.

D. Reverse transcription: Reverse transcription uses an RNA template to synthesize complementary DNA (cDNA); retroviruses use reverse transcriptase to perform this process.
