Give technical terms for the following.
Points at which two sister chromatids are held together.

Explanation

**Step-by-Step Solution:**

1. **Understanding Sister Chromatids**: Sister chromatids are identical copies of a chromosome that are connected together. They are formed during the S phase of the cell cycle when DNA is replicated.

2. **Identifying the Connection Point**: The question asks for the technical term that describes the point at which these two sister chromatids are held together.

3. **Defining the Term**: The specific point where two sister chromatids are joined is known as the "centromere." This is a constricted region of the chromosome that appears during cell division.
