Answer:

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.

Gene

  • is the basic physical and functional unit of heredity.
  • Genes are made up of DNA, a particular base sequence of DNA is termed as a gene for a specific protein.
  • Each gene is a unique base sequence.
  • Some genes act as instructions to make molecules called proteins. However, many genes do not code for proteins.
  • In humans, genes vary in size from a few hundred DNA bases to more than 2 million bases
  • These sequences are encoded in the form of mRNA during transcription and then move to the translation process and make proteins.

Thus, The section of DNA being used to make the strand of mRNA is known as - 2.  gene
