Chapter 11: Cell Growth and Division >

Regulatory proteins

Regulatory proteins

________ are signals that "tell "the cell when to divide, duplicate chromosomes, or enter another phase.

Pluripotent

________: cells that are capable of developing most, but not all, of the bodys cell types (can not form the tissues surrounding the embryo)

cell cycle

The ________ is strictly controlled to reduce the chances of serious illnesses (such as cancer)

M

________ phase: Stands for mitosis, the two new cells are produced in this stage.

Totipotent

________: can develop into any type of cell in the body (including the cells that make up the extraembryonic membranes and placenta)

Multipotent

________: the limited potential to develop into many different types of differentiated cells.

Chemotherapy

________ kills cancer cells or slows their growth since radiation destroys cancer cell DNA, but it can also destroy normal healthy cells.

Cell division

________ is constantly occurring in living beings, even when we stop growing.

Human embryonic stem cell research

________ is controversial because arguments for and against involve issues of life and death.

G1 phase

________: Cells increase in size, and new proteins /organelles are synthesized.

Cancer

________: Uncontrolled Cell Growth (when apoptosis doesnt work)

eukaryotic cells

In ________, DNA is packaged into multiple chromosomes and is more complex with multiple components.

Asexual Reproduction

________: The production of genetically identical offspring from a single parent.

Contact inhibition

________: cells can stop dividing once they come into contact, preventing tumors from developing (not all tumors are cancerous)

Cancer results

________ from a defect in genes that control cell growth and division.

Human adult stem cell research

________ Is rarely controversial because of willing donors.

excessive cell growth

Prevents ________ and tissues from disrupting one another.

Sexual Reproduction

________: The fusion of two reproductive cells formed by each of the two parents.

Asexual Reproduction

The production of genetically identical offspring from a single parent
