Cancer

3. An abnormal mass of cells that forms when cells divide more than they should or do not die when they should.
4. A cancerous tumor that can invade nearby tissues and spread to other parts of the body.
7. The process by which a cell divides to produce two identical daughter cells for growth and repair.
8. A small mammal often used as a model organism in scientific research because its biology is similar to humans and it reproduces quickly.
9. 1 The phase of the cell cycle where the cell grows and carries out normal functions before DNA replication.
10. A non-cancerous tumor that does not spread to other parts of the body.
12. A tumor-suppressor gene that helps control cell division and can trigger cell death if DNA damage is detected.
13. 2 The phase of the cell cycle after DNA replication where the cell prepares for mitosis.
14. A disease in which cells divide uncontrollably and can invade surrounding tissues.
16. The smallest unit of life that can carry out all vital functions of a living organism.

1. A group of organs that work together to perform major functions necessary for survival.
2. a scientist known for his work in tissue engineering, including growing tissues and organs in laboratories.
5. A group of similar cells that work together to perform a specific function.
6. A structure made of different tissues working together to carry out a particular function in the body.
7. The process by which cancer cells spread from the original tumor to other parts of the body.
11. 3 A resting phase where cells exit the cell cycle and do not divide, often temporarily or permanently.
15. Cycle The series of stages a cell goes through as it grows, copies its DNA, and divides.
