Front

What is the process by which a cell becomes specialized for a specific structure or function?

Back

Cell differentiation.

Front

What types of mutations can cause a frameshift mutation?

Back

Addition and deletion.

Front

What is cell specialization?

Back

The process by which generic cells change into specific cells with distinct functions.

Front

What role do environmental factors play in gene expression?

Back

They can influence whether genes are turned on or off.

Front

What is a mutation?

Back

A change in the DNA sequence that can lead to changes in protein function.

Front

What is the difference between addition and deletion mutations?

Back

Addition mutations involve inserting extra nucleotides, while deletion mutations involve removing nucleotides.

Front

What is the significance of stem cells in cell differentiation?

Back

Stem cells can develop into various specialized cell types.
