What does central dogma state in molecular biology? How does it differ in some viruses?

Explanation

### Step-by-Step Solution:

1. **Definition of Central Dogma**: The central dogma of molecular biology describes the flow of genetic information within a biological system. It outlines the processes of replication, transcription, and translation.

2. **Replication**: The first step in the central dogma is replication, which is the process of copying DNA. During replication, a DNA molecule serves as a template to produce two identical DNA strands.

3. **Transcription**: The second step is transcription, where the information in a DNA strand is transcribed to produce messenger RNA (mRNA). In this process, the DNA acts as a template to synthesize mRNA.
