What do you mean by molecular homology? What is its significance ?

Explanation

### Step-by-Step Text Solution

1. **Definition of Molecular Homology**:
Molecular homology refers to the similarities in biomolecular structures, such as proteins and nucleic acids (DNA/RNA), among different organisms. This similarity indicates that these organisms share a common evolutionary ancestor.

2. **Examples of Molecular Homology**:
A clear example of molecular homology can be seen when comparing the protein sequences or chromosomal sequences of different species. For instance, humans and apes exhibit significant similarities in their chromosomal structures despite differences in chromosome numbers (humans have 46 chromosomes while apes have 48).
