Question
Answer
An arrest in the cell cycle for repair   Check point  
🗑
Encodes gene products that inhibit unregulated cell division. Mutant alleles function recessively in promotion of a cancerous phenotype in a cell   Tumor suppressor gene  
🗑
Molecule that affects cell proliferation. Generally stimulate proliferation by associating with receptor proteins on the affected cell   Growth factor  
🗑
Programmed cell death in which the cell coordinates its own DNA degradation and nuclear condensation   Apoptosis  
🗑
Normal gene regulating cell proliferation that can become an oncogene when mutated   Proto-oncogene  
🗑
Steroids, peptides, and proteins that act over short and long distances to provide extracellular signals to cells.   Hormones  
🗑
Proteins that underlie the inner surface of the nuclear membrane and become soluble during mitosis to allow dissolution of the nuclear membrane into vesicles   Nuclear lamins  
🗑
The relaying of a signal through the cytoplasm to the nucleus in order to mediate a cellular response to an extracellular signal.   Signal transduction  
🗑
A family of proteins that phosphorylate specific substrates in response to a cell-cycle dependent association with specific cyclins.   Cyclin-dependent kinase  
🗑
Mutant allele of a proto-oncogene that acts dominantly to promote a cancerous phenotype   Oncogene  
🗑


   

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.
