According to the diagram shown, the section of DNA used to make the mRNA strand is known as a gene (option 2).

Explanation:

Gene consists of a DNA fragment that codes for the synthesis of a specific protein that defines the structural or functional trait of a living being.

When DNA is transcribed into mRNA, each section of transcribed DNA is part of a gene. The information travels to ribosomes in the cytoplasm where protein synthesis occurs.

A complete DNA molecule forms a chromosome, which contains the genes with information to define specific traits of a species.

The other options are not correct because:

    1.Carbohydrate is a biomolecule that is not involved in the genetic process.

    3. Ribosome is where protein synthesis occurs.

    4. Chromosome is the complete DNA molecule.
