Which of the following are enzymes are responsible for controlling the cell cycle?

Explain the apparent paradox that both hypermethylation and hypomethylation of DNA are often found in the same cancer cell.

As part of a cancer research project, you have discovered a gene that is mutated in many metastatic tumors. After determining the DNA sequence of this gene, you compare the sequence with those of other genes in the human genome sequence database. Your gene appears to code for an amino acid sequence that resembles sequences found in some serine proteases. Conjecture how your new gene might contribute to the development of highly invasive cancers.

Which of the following is NOT a cause of cancer?

Which of the following statements about cancer is false?

In this chapter, we focused on cancer as a genetic disease, with an emphasis on the relationship between cancer, the cell cycle, and DNA damage, as well as on the multiple steps that lead to cancer. At the same time, we found many opportunities to consider the methods and reasoning by which much of this information was acquired. From the explanations given in the chapter,

How do we know that cancer cells contain defects in DNA repair?
