When comparing and contrasting the various forms of RNA, the pathophysiology instructor identifies that ribosomal RNA (rRNA) is unique in that it:
A) Is produced in the nucleolus
B) Delivers activated amino acids
C) Is formed by transcription
D) Coordinates RNA translation
Ans: A
Feedback:
Ribosomal RNA (rRNA) is produced in the nucleolus and combines with ribosomal proteins in the nucleus to produce the ribosome. Transfer RNA (tRNA) delivers the activated form of amino acids to protein molecules in the ribosome. Messenger RNA (mRNA) is formed by the transcription process. Translation (protein synthesis) requires the coordinated actions of mRNA, tRNA, and rRNA.
