**Step-by-Step Text Solution:** 1. **Understanding the Concept of Collinearity**: The term "collinear" refers to the direct correspondence between the sequence of nucleotides in a gene and the sequence of amino acids in a polypeptide. This means that the order of nucleotides in DNA directly determines the order of amino acids in a protein. 2. **Role of DNA and Genes**: Genes are segments of DNA that carry the instructions for synthesizing proteins. When a gene is expressed, it undergoes transcription to produce messenger RNA (mRNA). 3. **Transcription Process**: During transcription, the DNA sequence of a gene is copied into mRNA. This mRNA then serves as a template for translation, where the sequence of nucleotides in the mRNA is translated into a sequence of amino acids. ...
