Question

If a scientist observes multiple ribosomes attached to a single mRNA molecule, what can they conclude about the protein synthesis process occurring?

B VENKAT · Accepted Answer

## CORE INFORMATION
✓ **Answer**: C. Multiple copies of a protein are being synthesized simultaneously.
## CONCEPT FRAMEWORK
 **Primary Concept**: Protein Synthesis and Polyribosomes
 **Related Topics**: Translation, Ribosomes, mRNA, Polypeptide chains
 **Prerequisites**: Basic understanding of the process of translation and the function of ribosomes in protein synthesis.
## SOLUTION PATHWAY
**Given Information**:
Multiple ribosomes are attached to a single mRNA molecule.
**Method & Steps**:
 1. Deduce the consequence of multiple ribosomes translating a single mRNA molecule.
  Reasoning: Each ribosome synthesizes a polypeptide chain.  The presence of multiple ribosomes on one mRNA suggests multiple protein copies are being produced simultaneously.
  Formula/Rule: No formula is needed. This is a logical deduction based on the understanding of protein synthesis.
 2. Analyze the implications of this observation.
  Working: Since each ribosome independently synthesizes a polypeptide chain based on the mRNA sequence, the presence of multiple ribosomes on a single mRNA implies that multiple copies of the same protein are being synthesized concurrently.
  Key Point: This is a highly efficient way to produce large quantities of a specific protein.
 3. Select the correct conclusion.
  Result: Multiple copies of the protein are being produced simultaneously.
  Verification: This conclusion directly follows from the given observation and the mechanism of protein synthesis.
 ## OPTION ANALYSIS
A :x:  mRNA degradation is not directly implied by the presence of multiple ribosomes on the mRNA.
B :x: Protein synthesis inhibition is the opposite of what is observed.
C ✓: Multiple copies of a protein being synthesized simultaneously is the direct consequence of multiple ribosomes translating the same mRNA.
D :x: Only a single protein copy is inconsistent with the observation of multiple ribosomes.
 ## LEARNING AIDS
 **Common Mistakes**:
  1.Misinterpreting the role of ribosomes:  Understanding that each ribosome synthesizes one polypeptide chain is crucial.
  2.Overlooking the simultaneous aspect: The key is that multiple ribosomes are working at the same time.
 **Quick Tips**:
  1.Think about the function of ribosomes in protein synthesis.
  2.Visualize the ribosomes moving along the mRNA, each producing a protein copy.

B VENKAT · Answer

The mRNA is being degraded.

B VENKAT · Answer

Protein synthesis is inhibited.
