The correct statement about genes is: "One gene codes for one mRNA which codes for one protein."

Here's why:

1. "Each chromosome has exactly one gene." - This is incorrect. Each chromosome actually contains hundreds to thousands of genes.

2. "Genes are made by transcription." - This is also incorrect. Transcription is the process where the DNA sequence of a gene is copied into mRNA, not the creation of genes.

3. "The DNA in genes is single-stranded." - This is incorrect. The DNA in genes is double-stranded.

4. "One gene codes for one mRNA which codes for one protein." - This is correct. In general, one gene codes for one mRNA molecule, which can then be translated into a protein. However, it's important to note that one gene can code for multiple proteins through a process called alternative splicing.
