Week 2: DNA, Cell Cycle and Cancer

How does DNA replication relate to cancer? Use evidence from any one of the links in the "Practical Application" section.

In the article "Unavoidable Typos in DNA Help Fuel Cancer" the author tells us that every time DNA is copied it creates about three random mutations. But that isn't the problem because often times it takes place in genes that have no relation to cancer at all. The problem occurs when the errors happen in wrong spots in our genes and create abnormal cancer growth.

Adding on to what madox said, the author also tells us that a person can carry a mix of mutations in different parts of the body. However, that is not the reason for cancer. The reason is that different organs in the body are more susceptible to cancer from different factors. For example, the author says that the research found states that 77% of pancreatic cancer occurs from mutations while most lung cancers occur from lifestyle choices like smoking.

Do you have any questions for me?

If more cell divisions occur does that make the cancer more deadly?

Not necessarily, it just makes it more likely

how can DNA replicated into conservative and dispersive DNA? do we need to know them?

No, that is more detail then i expect you to know :)

If a cell has multiple nucleoli, is that a reliable warning sign of a cancerous cell? How about a coarse chromatin?
