Most of the life cycle of a cell is spent in in what phase of the cell cycle? 

• Mitosis 
• Interphase
• Cytokinesis
• Sythesis 

Interphase contains three stages, including the G1 and G2 stages.  WHich of the following occurs during these gap stages? 

• separation of chromosomes
• cellular growth 
• DNA replication
• viral transformation 

During interphase, the DNA is replicated to create two complete sets of DNA.  The DNA is copied during which stage of the cell cycle? 

• G1
• S
• G2
• M

Before DNA can be replicated, the DNA must separate-- 

• between the phosphate groups
• behind the deoxyribose sugars
• from the sugar-phosphate backbone
• between the nitrogen bases

When DNA replication is complete, each set DNA is --

• genetically identical 
• contains gene splicing 
• is genetically unique and is not like the parent strand
• there are 46 new strands of DNA that are all identical

The purpose of mitosis is to separate the two sets of DNA created during replication and -- 

• redirect the expression of genes
• discard the unwanted genes
• place them into two nuclei
• mutate them into new sequences 

If a fruit fly has 8 chromosomes in each of its body cells, how many chromosomes will be in each daughter cell after mitosis? 

• 2
• 4
• 8
• 16

The final stage of cellular division involves the separation of the two nuclei along with the cytoplasm into two new daughter cells. This process is known as --

• cytokinesis
• repiration
• meiosis
• mitosis
