Benchmark 2 review #2

Which occurs during cytokinesis?

• binary fission

• cytoplasm divides

• DNA duplicates

• spindle apparatus forms

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 alleles are exchanged

The correct order of the phases of mitosis and meiosis could be abbreviated as:

• MAPT
• PAMT
• TPAM
• PMAT

DNA is replicated during the ______ phase of the cell cycle.

• G₁
• Synthesis
• G₂
• G₀

During what stage does the G₁, S and G₂ phases happen?

• Interphase
• M phase
• Mitosis
• Cytokinesis

The end of meiosis results in  ____ to each other.

• 2 cells that are identical
• 4 cells that are identical
• 2 cells that are not identical
• 4 cells that are not identical

Meiosis results in the production of

• 2 diploid cells
• 2 haploid cells
• 4 haploid cells
• 4 diploid cells

A chromosome is packaged

• DNA

• Protein

• Carbohydrates

• Lipids

Fruit fly body cells have 8 chromosomes. After mitosis you would expect the resulting fruit fly daughter cells to have… chromosomes.

• 16

• 8

• 4

Why would it be important to replicate DNA before a cell divides in mitosis or meiosis?

• In order for the genetic information to be transferred into daughter cells

• In order for the DNA to be contained in the nucleus

• In order for the cell to be able to increase in size
