Mitosis vs. Meiosis

This image shows chromosomes during Prophase 1. Which of the following correctly describes the process shown?

• segregation of sister chromatids

• condensation and segregation of alleles

• mutationin which the DNA content of the gene is altered

• crossing - over in which genes are exchanged

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.
