The bond present between two nucleotides is known as

Options

A. Phosphoester linkage
B. Phosphodiester linkage
C. Glycosidic linkage
D. Peptide linkage

Answer

To solve the question regarding the bond present between two nucleotides, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Nucleotides**:
- Nucleotides are the building blocks of nucleic acids (DNA and RNA). Each nucleotide consists of a sugar, a phosphate group, and a nitrogenous base.

2. **Identifying the Bond**:
- The bond that connects two nucleotides is crucial for forming the backbone of DNA or RNA.

3. **Types of Bonds**:
- There are different types of bonds in nucleic acids, including:
- **Phosphodiester Linkage**: This bond forms between the phosphate group of one nucleotide and the 3' carbon of the sugar of another nucleotide.
- **Glycosidic Linkage**: This bond connects the nitrogenous base to the sugar in a nucleotide, but it does not connect two nucleotides together.

4. **Correct Answer**:
- The bond that connects two nucleotides is known as **Phosphodiester Linkage**. This bond occurs specifically between the 3' carbon of one sugar and the 5' carbon of another sugar.

5. **Conclusion**:
- Therefore, the correct answer to the question is **Phosphodiester Linkage**.

### Final Answer:
The bond present between two nucleotides is known as **Phosphodiester Linkage**.
