Question

After mitosis, some cells go through the process of differentiation, which makes them more specialized. Even though they all have the same DNA, they are able to perform these specialized functions because of gene expression, meaning only the 'necessary' part of the DNA is being used. Gene expression is influenced by:

1) Environmental factors
2) Hormones
3) Developmental signals
4) All of the above

Answer 1

Cells become specialized through differentiation, which is influenced by environmental factors, hormones, and developmental signals. Option 4. all of the above is correct.

Step-by-step explanation:

Differentiation is a process in which cells become more specialized, undergoing changes in size, shape, metabolic activity, and function. Despite having the same DNA, cells are able to perform specialized functions due to gene expression, where specific parts of the DNA are used. Gene expression can be influenced by environmental factors, hormones, and developmental signals, meaning that all of the above options (1) Environmental factors, (2) Hormones, and (3) Developmental signals, are correct answers for what influences gene expression.
