What is apoptosis?
a means of initiating DNA replication during growth
a means of removing unneeded proteins from
a cell a process used by cancer cells to migrate through the body
a process in which cells direct their own destruction
When does a cell use apoptosis?
Antibodies produced by the immune system use apoptosis to destroy foreign organisms.
After a cell has become cancerous, it will rapidly begin the process of apoptosis.
Existing cells go through apoptosis to produce new cells that are needed for growth.
If a cell is damaged or no longer needed, apoptosis may be initiated.
Homework Answers
Apoptosis- it is a process in which cells directs their own death. It is also called 'programmed cell death'.
A cell uses apoptosis when it is no loner needed or the cell gets damaged.
The process is characterized by shrinking of cell, blebbing, fragmentation of DNA,chromatin and nucleus. It is mediated by caspases that are proteolytic enzymes.

A cell's genome is its blueprint for life. However, what is the bare minimum number of genes needed to sustain a free-living cell? This is a question that microbiologists at the J. Craig Venter Institute (JCVI) have attempted to answer ever since they sequenced the genomes of several Mycoplasma species in the 1990s. Because Mycoplasma species are parasitic bacteria, their genomes are already reduced in size and hence provide an excellent foundation for creating a "minimal cell." However, little did...
