Q. 17.108 - An Introduction to General, Organic, and Biological Chemistry

Question

Match the following statements with rRNA, mRNA, or tRNA:
a. combines with proteins to form ribosomes
b. brings amino acids to the ribosomes for protein synthesis
c. acts as a template for protein synthesis

Step-by-Step Solution

Answer

Part(a) rRNA combines with proteins to form ribosomes

Part(b) tRNA brings amino acids to the ribosomes for protein synthesis

Part(c) mRNA acts as a template for protein synthesis

Part(a) Step 1 : Given information

We need to find which RNA combines with proteins to form ribosomes

Part(a) Step 2 : Simplify

Ribosomal RNA, a type of structural RNA that interacts with proteins to form the ribosome, is encoded by portions of DNA on particular chromosomes.
New ribosomal RNA mixes with proteins in the nucleolus to generate the ribosome's subunits.

Part(b) Step 1 : Given information

We need to find which RNA brings amino acids to the ribosomes for protein synthesis

Part(b) Step 2 : Simplify

Amino acids are delivered to the ribosome via transfer RNAs (tRNAs). The tRNA joins the mRNA by matching similar nucleotides.This guarantees that the protein contains most of the essential amino acids.

Part(c) Step 1 : Given information

We need to find which RNA acts as a template for protein synthesis

Part(c) Step 2 : Simplify

DNA replicates to generate other DNA, and it is transcribed from mRNAs, which serve as templates for the translation of proteins, according to cell biology's basic dogma.
As a result, the correct answer is mRNA.
