Mitosis & Cell Division

Which of the following are the reasons that a cell needs to divide? [SELECT ALL THAT APPLY]

• Allows multicellular organisms to grow

• Cells do not divide, they just keep growing larger

• Repair damage that has occurred

• Replace old cells that are no longer working properly

When a cell divides during mitosis it produced two identical ____________ cells.

Which statement best describes why it is important for the cell to replicate its DNA before it goes through cell division?

• The cell isn't big enough to copy DNA after division

• The cell needs to copies of the DNA to split between the two new cells that will be made

• The cell goes through a checkpoint during replication so it is the best time to make a copy

• The cell does not replicate its DNA before it goes through cell division.

A __________ is tightly condensed structure made up of chromatin, and DNA tightly wrapped around proteins.

• Chromosome

• DNA

• Histone

• Nucleotide
