|
Cells differentiate to perform different functions because
|
|
all genes are turned on inside that cell
|
|
|
all genes are turned off inside that cell
|
|
|
different genes are turned on inside that cell
|
|
|
different genes are turned on or off inside that cell
|
Explanation:
Detailed explanation-1: -Cell differentiation is how generic embryonic cells become specialized cells. This occurs through a process called gene expression. Gene expression is the specific combination of genes that are turned on or off (expressed or repressed), and this is what dictates how a cell functions.
Detailed explanation-2: -Gene regulation makes cells different Thanks to gene regulation, each cell type in your body has a different set of active genes-despite the fact that almost all the cells of your body contain the exact same DNA.
Detailed explanation-3: -Epigenetics allows the muscle cell to turn “on” genes to make proteins important for its job and turn “off” genes important for a nerve cell’s job.
