multiple - choice question
growth occurs in an organism when dna is used to
change the overall appearance/structure of the organism

Explanation:

Growth in an organism is mainly due to cell - division and cell - addition which is regulated by DNA. DNA provides the instructions for cell growth and division, leading to an increase in the number of cells and thus the organism getting bigger or taller. It's not about changing the overall appearance/structure directly in the context of basic growth.

Answer:

add new cells and the organism gets bigger/taller
