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 (a)   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
