Term
| One Set of DNA (Reason why cells divide) |
|
Definition
| Cell only has one set of DNA or genetic instructions which direct cell activity |
|
|
Term
| Surface Area to Volume Ratio (Reason why cells divide) |
|
Definition
| Cells want to maximize surface area and minimize volume. |
|
|
Term
| Specialization (Reason why cells divide) |
|
Definition
| The more cells an organism has the more specific a role each can play. Seen in multi-cellular organisms only!!!! |
|
|
Term
|
Definition
| these are simple, unicellular bacteria with no organelles or nucleus and a singular, circular chromosome |
|
|
Term
|
Definition
| these are more complex, unicellular or multicellular, have organelles and a nucleus, and have multiple linear chromosomes |
|
|
Term
|
Definition
| when prokaryotes grow to certain size they replicate their DNA and then split themselves into two genetically identical cells |
|
|
Term
|
Definition
| The 1st GAP of a cell’s life consist of cell growth and normal activity |
|
|
Term
|
Definition
| The cell synthesizes copies of its DNA. |
|
|
Term
|
Definition
| Cell prepares for division by producing proteins and organelles for division |
|
|
Term
|
Definition
| is the process of dividing the nucleus within Eukaryotes |
|
|
Term
|
Definition
| The 1st thing is chromosomes condense by supercoiling.Then nucleus dissolves to get at replicated chromosomes.Spindle fibers will form and attach to chromosomes. |
|
|
Term
|
Definition
| During this phase the chromosomes line down the middle of the cell. They are moved there by spindle fibers. The chromosomes line up to make sure each cell gets one copy of each chromosome |
|
|
Term
|
Definition
| Spindle fibers pull chromosomes away from each other towards each pole of the cell. The chromosome rips in half between the two identical chromatids. This makes chromatids now individual chromosomes. |
|
|
Term
|
Definition
| Each pole has a set of chromosomes with nucleus reforming. Chromosomes will decondense back into chromatin. Spindle fibers disintegrate. Complete opposite of prophase! |
|
|
Term
|
Definition
| Is the division of the cytoplasm and organelles.Cell membrane furrows inward, creates a cleavage. Cell plate (beginning of cell wall) forms, (Plants Only).Cell membrane pinches off and two genetically identical daughter cells have been formed |
|
|
Term
|
Definition
| Requires One Cell. Single cell divides into new cells. Occurs more quickly because no mate needed. Produces genetically identical cell |
|
|
Term
|
Definition
| Requires two cells. Two cells combine to form one new cell. Takes time to create cell and find a mate for completion. Produces genetically recombined cell |
|
|
Term
|
Definition
| is a technique used to examine an individual’s chromosomes to detect abnormalities |
|
|
Term
|
Definition
| protein which regulates the cell cycle phases.rises throughout a cell’s life and peaks right before cell division. |
|
|
Term
|
Definition
| stimulates growth and cell division during injuries and embryonic development |
|
|
Term
|
Definition
| when cells have lost the ability to regulate their growth and division |
|
|
Term
|
Definition
| A mass of cancerous cells |
|
|
Term
|
Definition
| are undifferentiated cells that have the ability to develop into different types of tissues. Use undifferientiated cells to repair or replace damaged wounds. |
|
|
Term
|
Definition
| totally” potent, these stem cells can become any cell. This is only the fertilized egg |
|
|
Term
|
Definition
| “more” potent, these stem cells can become almost any body cell. These cells are harvested from embryos or can be reversed engineered |
|
|
Term
|
Definition
| these stem cells can become only a few different types of cells. These are found in your bone marrow and harvested from umbilical cords. |
|
|
Term
|
Definition
| is a process of programmed cell death. Once triggered, a cell undergoes a series of controlled steps leadinf to isw self-destruction. |
