The central dogma in molecular biology involves DNA `to` RNA `to` Proteins.

Explanation

### Step-by-Step Solution

1. **Understanding the Central Dogma**: The central dogma of molecular biology describes the flow of genetic information within a biological system. It is a framework that explains how genetic information is transferred from DNA to RNA and then to proteins.

2. **DNA Replication**: The first step in the central dogma is DNA replication. This process involves the duplication of the DNA molecule, ensuring that each new cell has an identical copy of the DNA. This is essential for cell division and inheritance.

3. **Transcription**: After DNA replication, the next step is transcription. During transcription, a specific segment of DNA is copied into messenger RNA (mRNA). This process occurs in the nucleus of the cell. The enzyme RNA polymerase binds to the DNA and synthesizes a single strand of mRNA based on the DNA template.
