What is the name of basic protein present in chromatin?

Answer

### Step-by-Step Solution

1. **Understanding Chromatin**: Chromatin is a complex of DNA and proteins found in the nucleus of eukaryotic cells. It plays a crucial role in packaging DNA into a smaller volume to fit in the cell and protect the DNA structure and sequence.

2. **Components of Chromatin**: Chromatin consists of DNA and proteins. The DNA is negatively charged, which is important for its interaction with proteins.

3. **Identifying the Basic Protein**: The basic protein that is present in chromatin is called **histone**. Histones are positively charged proteins that bind to the negatively charged DNA, helping to organize and condense the DNA into a compact structure.

4. **Function of Histones**: Histones play a critical role in the packaging of DNA into nucleosomes, which resemble "beads on a string." This structure is essential for the efficient storage of genetic information and regulation of gene expression.

5. **Synthesis of Histones**: Histone proteins are synthesized during the S phase of the cell cycle, which is when DNA replication occurs. This ensures that there are enough histones available to package the newly synthesized DNA.

### Final Answer
The basic protein present in chromatin is called **histone**.
