4 1. Expansion & breakthrough

5 2. Fix & healing

*

6 1. Development & development 2. Repair & heal 3. Reproduction (in asexual organisms)

*

7 Cyclins room a family of protein that regulate the time of the cabinet cycle Cyclins “tell” the cell as soon as to:  Replicate chromosomes  division  Enter another phase the the cell cycle

*

8 Cyclin production during interphase signals cabinet to get in mitosis Cyclin damage during mitosis signals cabinet to prevent dividing and enter interphase direction (5 min total) open up textbook come p.288 Answer inquiries 1-3 with companion

*

9 When during the cell cycle go cyclin production occur? Cyclin production reasons the cell to a) get in interphase b) prepare for mitosis c) end mitosis d) increase energetic transport

*

10 When during the cabinet cycle walk cyclin devastation occur? Cyclin destruction reasons the cabinet to a) enter interphase b) prepare for mitosis c) experience cytokinesis d) increase energetic transport

*

11 countless other factors help regulate the cell cycle: internal regulators respond to occasions inside the cabinet (attachment the spindle fibers, DNA replication, etc) These inner regulators allow the cabinet cycle come proceed just when specific events (like DNA replication) have been perfect

*

12 external regulators answers to occasions outside the cabinet (growth factors, cell surface ar proteins, etc) this regulators can direct cells to speed up or slow-moving down the cell cycle

*

13 What is one occasion an inner cell bicycle regulator could detect or answers to? an example of an external cell bicycle regulator would be a) DNA polymerase b) Cyclins c) Spindle fiber protein d) Growth determinants

*

14 Apoptosis is “programmed cell death” with a series of controlled steps cell commit “suicide” as part of normal growth and development

*

15 Apoptosis is vital to shaping frameworks of tissues and also organs in plants and also animals Cells v mutations or problems with DNA replication also undergo apoptosis http://www.dnatube.com/video/1188/Apoptosis-animation computer mouse Embryo Paw

*

16 Apoptosis is important for a) ensuring mitosis occurs generally b) proper development of organs and body frameworks c) avoiding mutated cells from farming d) a-c e) b-c f) a and c

*

17 Cancer is a team of disorders defined by untreated cell division Uncontrolled cell department creates tumors (masses the cancer cells) benign tumors execute not spread and are usually treatable Malignant tumors do spread, invading and also damaging other tissues Melanoma

*

18 Cancer is usually led to by mutations come a cell’s regulatory genes (causes the mutations incorporate tobacco, radiation, organic mutations, and viral infections) together a result, regulate over the cell cycle division down: 1. Cells nothing respond to exterior growth determinants 2. Cells fail to create internal regulators 3.

Mutated cell fail to undergo apoptosis

*

19 Cancer is commonly treated through: surgical treatment Radiation Chemotherapy targeted Therapy: (Newer methods - regularly use antibodies of immune system proteins to destroy cells) classic Treatment options
