Cancer Genes

Will a cancer cell do more or less mitosis than a normal cell?

• More because cancer is uncontrolled mitosis (cell growth/division)

• Less because cancer prevents cells from dividing/doing mitosis

What is a mutation?

• A temporary change in the sequence of the DNA inside a cell

• A permanent change in the sequence of the DNA inside a cell

• A virus that attacks the DNA inside a cell

• Bacteria that attack the DNA inside a cell

What happens when the genetic code in a gene is altered?

• This situation has never occurred

• A defective protein is produced, causing a mutation.

• The genetic code is corrected by the lysosomes.

• Nothing changes; the correct proteins are still made.
