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.

• Crossing over provides genetic diversity in eukaryotic cells

In mitosis, one parent cell -

• Forms two identical daughter cells

• Forms four identical daughter cells

• Forms two genetically diverse daughter cells

• Forms four genetically diverse daughter cells

During prophase I crossing over occurs and genetic material is exchanged between homologous chromosomes. How is this important

• Increases genetic variation

• Reduces the diploid number to the haploid number

• Increases the haploid number to the diploid number

• Reduces the probability of mutations
