Answer:

A section

of DNA that provides information for one protein is called the gene for that protein.

Let us take the example of tallness as a characteristic. We know that plants have

hormones that can trigger growth. Plant height can thus depend on the amount of a

particular plant hormone. The amount of the plant hormone made will depend on

the efficiency of the process for making it. CONSIDER now an enzyme that is

important for this process. If this enzyme works efficiently, a lot of hormone will be

made, and the plant will be tall. If the gene for that enzyme has an ALTERATION that

makes the enzyme less efficient, the amount of hormone will be less, and the plant

will be short. Thus, genes control characteristics or traits

1) How is protein made in a cell?

1) What are the factors that control the physical expression?

1) How is growth RELATED to DNA?

iv) What happens if a gene has an alteration?
