Chromosome having terminal centromere capped by telomere is

Options

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

Answer

To solve the question "Chromosome having terminal centromere capped by telomere is?", we need to understand the different types of chromosomes based on the position of the centromere. Here’s a step-by-step breakdown:

### Step 1: Understand Chromosome Structure
Chromosomes are structures within cells that contain DNA. They are made up of two arms, which are separated by a centromere. The position of the centromere can vary, leading to different types of chromosomes.

**Hint:** Recall that the centromere is the point where the two chromatids are joined together.

### Step 2: Identify Types of Chromosomes
There are several classifications based on the centromere's position:
- **Metacentric:** Centromere is located in the middle, resulting in two equal arms.
- **Submetacentric:** Centromere is slightly off-center, leading to one shorter arm (P arm) and one longer arm (Q arm).
- **Acrocentric:** Centromere is located closer to one end, resulting in one very short arm and one long arm.
- **Telocentric:** Centromere is located at the very end of the chromosome, making one arm extremely short or nonexistent.

**Hint:** Visualize the position of the centromere to differentiate between these types.

### Step 3: Focus on the Question
The question specifically asks for a chromosome with a terminal centromere that is capped by a telomere. This description matches the telocentric chromosome, as the centromere is located at the end of the chromosome and is capped by telomeres.

**Hint:** Remember that telomeres are protective caps at the ends of chromosomes.

### Step 4: Conclude the Answer
Based on the definitions and characteristics discussed, the chromosome having a terminal centromere capped by a telomere is classified as **telocentric**.

**Final Answer:** Telocentric
