What is molecular homology ? Cite one example

Explanation

### Step-by-Step Solution:

1. **Definition of Molecular Homology**:
- Molecular homology refers to the similarity in the molecular structures of different organisms. This similarity can be observed at the level of DNA, RNA, or proteins. It implies that these organisms share a common ancestor due to the conserved nature of certain molecular sequences over time.

2. **Understanding the Terms**:
- The term "molecular" relates to molecules, which are the building blocks of biological structures, including proteins and nucleic acids.
- "Homology" comes from the Greek word "homologos," meaning "of the same kind." In biology, it indicates similarity due to shared ancestry.
