Biology B Final Exam Practice

Why would it be important to replicate DNA before a cell divides in mitosis or meiosis?

• In order for genetic information to be transferred into daughter cells.
• In order for the cell to be able to increase in size.
• In order for the DNA to be contained in the nucleus.
• In order for the cell to re-order the DNA sequencing in the new cells.

Cancer is best and fully described by ...

• Uncontrolled cell growth

• Cells that have mutations, uncontrolled cell growth, and no longer function correctly

• Cells which have lost the ability to reproduce

• Cells which create abnormal tissues

There are two main groups of genes that control the cell cycle. When these types of genes get mutated, cancer can develop. The type of genes that work like accelerators and tell the cell cycle to "Go" are....

• Apoptosis genes

• Tumor suppressor genes

• Tumor activator genes

• Proto oncogenes

What best describes why cancer is mostly found in old people?

• Old people have more wrinkles

• Cancer usually takes many mutations to get started and more accumulate over a life time

• Older people smoke more than younger people

• Only older people get mutations
