Question

Which of the protein is found in spindle fibre?

Mr. NARESH KUMAR K · Accepted Answer

## CORE INFORMATION
✓ **Answer**: A
## CONCEPT FRAMEWORK
	**Primary Concept**: Protein composition of cellular structures.
	**Related Topics**: Cell division, microtubules, protein types
	**Prerequisites**: Basic knowledge of cell biology and protein functions
## SOLUTION PATHWAY
**Given Information**:
	* The question asks about the protein component of spindle fibers.
**Method & Steps**:
	1. Recall the composition of spindle fibers:
		Reasoning: Spindle fibers are made of microtubules.
		Formula/Rule: Microtubules are formed by tubulin.
	2. Identify the correct option:
		Result: Tubulin is the protein that forms microtubules and therefore spindle fibers.
 ## OPTION ANALYSIS
[A] ✓: Tubulin is the protein that polymerizes to form microtubules, which are the main components of spindle fibers.
[B] :x: Albumin is a protein found in blood plasma, not in spindle fibers.
[C] :x: Mucin is a component of mucus, not spindle fibers.
[D] :x: Haemoglobin is a protein in red blood cells that carries oxygen, not related to spindle fibers.
 ## LEARNING AIDS
	**Common Mistakes**:
		1.[Confusing proteins]: [Students may confuse proteins with different functions. Remembering key associations helps. For instance, Tubulin - Microtubules, Haemoglobin - Oxygen transport]
	**Quick Tips**:
		1.[Mnemonic]: To remember tubulin's role in spindle fibres, think 'Tubules in Spindle'.
