|
||||
|---|---|---|---|---|---|
| DNA replication | the process of producing two identical copies of one original DNA molecule
🗑
|
||||
| mitosis | followed by cytokinesis, this division of the nucleus produces two identical, diploid (2n) body cells
🗑
|
||||
| chromosome | made up of DNA wrapped around proteins (human body cells have 46 (diploid/2n) located in the nucleus)
🗑
|
||||
| reception | the first stage of cell communication in which a chemical messenger (a ligand) attaches to a specific receptor protein, causing the receptor protein to change shape
🗑
|
||||
| transduction | the second stage of cell communication triggered by the shape change in the receptor protein and passed on through signal cascades, second messengers and/or protein modifications
🗑
|
||||
| response | the third and final stage of cell communication in which a cell responds to the original message
🗑
|
||||
| hormones | one of many types of circulating chemical signals in all multicellular organisms that travel in body fluids and interact with target cells
🗑
|
||||
| ligand | a molecule that binds specifically to a receptor site of another molecule
🗑
|
||||
| receptor protein | on or in a cell, a specific protein molecule whose shape fits that of a specific molecular messenger, such as a hormone
🗑
|
||||
| second messenger | a small, nonprotein molecule or ion, such as cyclic AMP (cAMP) , that relays a signal to a cell's interior in response to a signal received by a signal receptor protein
🗑
|
||||
| cell cycle | a complex set of stages with checkpoints that regulates growth, DNA synthesis and duplication
🗑
|
||||
| G2 checkpoint | must be passed before a cell enters mitosis and is triggered by the joining of cyclin and cdk to form MPF
🗑
|
||||
| karyotype | the result of method of organizing the chromosomes of a cell in relation to number, size, and type
🗑
|
||||
| cancer | a disease caused by an uncontrolled division of abnormal cells in a part of the body
🗑
|
||||
| cyclin | a regulatory protein in cells whose concentration fluctuates cyclically (binds with Cdk to form MPF and allow the cell to pass the G2 checkpoint
🗑
|
||||
| Cdk | a protein kinase that is active only when attached to cyclin, forming MPF to allow the cell to pass the G2 Checkpoint
🗑
|
||||
| positive feedback | a physiological control mechanism in which a change in some variable triggers mechanisms that amplify the change
🗑
|
||||
| negative feedback | a primary mechanism of homeostasis, whereby a change in a physiological variable that is being monitored triggers a response that counteracts the initial fluctuation.
🗑
|
||||
| telophase | The fourth stage of mitosis: the nucleus divides into two nuclei
🗑
|
||||
| metaphase | The second stage of mitosis: cell's duplicated chromosomes line up at cell's equator
🗑
|
||||
| prophase | The first stage of mitosis: duplicated chromosomes condense, mitotic spindle forms/begins moving the chromosomes toward the center of the cell made possible by the breakdown of the nuclear envelope
🗑
|
||||
| cytokinesis | division of the cytoplasm to form separate daughter cells immediately after mitosis or meiosis
🗑
|
||||
| interphase | cell cycle section including growth, synthesis of DNA and mitosis prep -- 90% of cell cycle time
🗑
|
||||
| anaphase | The third stage of mitosis: sister chromatids separate from each other
🗑
|
||||
| onion root tip | a rapidly growing part of the onion and thus many cells will be in different stages of mitosis
🗑

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
