Cell specialization

This type of cell is not yet specialized, but has the ability to turn into a variety of specialized cell types. It is used in research to treat a variety of medical ailments and diseases.

• stem cell
• bone cell
• nerve cell
• gamete

Embryonic stem cells are

• cells that grow uncontrollably

• cells present early in development that can form into any type of cell

• not able to go through cell division

• found within the tissues of a fully developed human

What causes differentiation?

• The DNA is different in each type of cell.

• Some cells have more or less DNA than others.

• Only specific genes in the DNA are activated, or "cut on".

• a special type of mutation in bacteria cells

• a cell has differentiated into a specific type of cell

• the replication of DNA

In embryonic development,  the process by which cells specialize is called

In what way is the DNA of a nerve cell different from the DNA of a muscle cell?

• The DNA is the same but each cell contains different genes
• The DNA is the same but different genes are turned on and turned off in each cell
• The DNA is different, but the same genes are turned on and off in each cell
• The DNA is different, but each cell contains the same genes

Cells that are not yet specialized, like stem cells, are said to be:

• Undifferentiated, or unspecialized

• Specialized

• Disfunctional

• Inactive

All bodily cells have the same DNA. True or False?

• True

• False

What makes a muscle cells different from a nerve cell?

• They have different DNA to make them those specialized cell types.

• They have different portions of activated DNA.

• They experience different environmental influences.

• They have different genes.
