TRUE OR FALSE A stem cell can  reproduce itself indefinitely and differentiate into special­ized cells of one or more types.

Define apoptosis and explain why it is an important process in multicellular organisms. Give specific examples.  own words

Ordinary cell division produces two daughter cells that are genetically identical. This type of cell division is important for all of the following functions EXCEPT     cell replacement.     growth of a multicellular organism.     production of sperm and eggs.     asexual reproduction.

If all the stem cells were removed from a holocrine gland, what effect will this have on long term function of that gland.   Increase, decrease or no change. With explanation

Complete the questions below regarding the control of cell division. There were at least 7 different ones discussed in the lecture. List 5 of the control factors that help to regulate cell division in your body and then tell me how that control factor does that in the second column. Control Factor How does it control the cell cycle? a. f. b. g. С. h. d. i. е. j.

The functions of the cell part labeled “Z” include —

Reports in the media about stem cells usually state that they “turn into any kind of cell in the body.” Explain why this statement is only partially correct, including a description of how a stem cell maintains the population of stem cells.

HeLa Cells are the most widely used human cell line. They have been used in thousands of studies, leading to countless discoveries. These cells were unknowingly taken from Henrietta Lacks, a Johns Hopkins Medical Center patient. Dr. Gey at Johns Hopkins Medical Center took some of the cells from Mrs. Lacks's cancer and discovered that they could keep growing and dividing indefinitely. Mrs. Lacks did not know these cells were taken from her and neither did any of her family members.  Today, strict guidelines protect individuals participating in a federally funded research study (e.g., in a clinical trial).  The study has to go through a lengthy review and participants receive information about all aspects of the study and provide “informed consent” to participate. These guidelines are known as the Common Rule.  However, the Common Rule does not apply to cells or tissues removed during medical procedures. Scientists can use leftover tissues from surgeries, and biopsies for research…

____________ is the most common tumor suppressor gene that is often mutated in human cancers.

True or false: A somatic cell mutation may be passed on to offspring.
