Microsatellite sequences are repeat units with base pairs

Options

A. `1-6`
B. `5-30`
C. `11-60`
D. `20-120`

Answer

To solve the question about microsatellite sequences and their repeat units in base pairs, follow these steps:

### Step 1: Understand the Definition of Microsatellites
Microsatellites are short, repetitive sequences of DNA that consist of repeating units. These units are typically composed of 1 to 6 base pairs.

**Hint:** Look for the specific range of base pairs that define microsatellites.

### Step 2: Analyze the Options Provided
The options given are:
1. 1 to 6
2. 5 to 30
3. 11 to 60
4. 20 to 120

**Hint:** Compare each option with the definition of microsatellites.

### Step 3: Identify the Correct Range
From the definition, we know that microsatellites consist of repeating units that are 1 to 6 base pairs in length. Therefore, the correct option is 1 to 6.

**Hint:** Focus on the range that matches the definition of microsatellites.

### Step 4: Confirm the Use of Microsatellites
Microsatellites can be amplified using techniques like Polymerase Chain Reaction (PCR) and are often used as molecular markers in genetic studies.

**Hint:** Consider how microsatellites are utilized in genetics and their importance in identification.

### Final Answer
The correct answer is **1 to 6 base pairs**.
