Question

A chromosome with centromere near the middle is called:

• A. Metacentric
• B. Acrocentric
• C. Telocentric
• D. Submetacentric

Hint:

Metacentric: centromere in middle (V-shaped).
Submetacentric: centromere between middle and end.
Acrocentric: centromere near end.
Telocentric: centromere at end.

Answer 1

The Correct Option is A

Step 1: Understanding the Concept:
Chromosomes are classified based on centromere position.
The position affects chromosome shape.

Step 2: Key Formula or Approach:
No specific formula.
Need to know the types of chromosomes based on centromere.

Step 3: Detailed Explanation:
Metacentric chromosomes have the centromere near the middle.
This gives V-shaped chromosomes.
Acrocentric: centromere near one end.
Telocentric: centromere at the end.
Submetacentric: centromere between middle and end.
Thus, a chromosome with the centromere near the middle is metacentric.

Step 4: Final Answer:
A chromosome with centromere near the middle is metacentric.
Hence, the correct option is (A).
