Mitosis and Meiosis

What phase of mitosis is occuring in the picture?

• Prophase
• Metaphase
• Cytokinesis
• Telophase

In which phase does the cell spend most of it's life?

• Interphase
• Nuclear Division
• Telophase
• Mitosis

Why do we need meiosis?

• To double the number of chromosomes going into sex cells
• To halve the number of chromosomes going into sex cells
• To triple the number of chromosomes going into sex cells
• To not change the number of chromosomes going into sex cells

The result of meiosis is:

• two diploid cells
• two haploid cells
• four diploid cells
• four haploid cells

The chromosomes that pair up during meiosis, are called __________ chromosomes.  

• homozygous 
• asexual
• homologous
• genes

A human zygote should have _____ chromosomes inside.

• 46
• 23
• 92
• 64

This picture shows which process? 

• mitosis
• meiosis
• the cell cycle

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.

In the following structure, the circled item is a

• chromosome

• chromatid

• centromere

• chromatin

Structure (b) is a ____.

• chromosome
• chromatid
• centromere
