Cell Division Review

When a cell is not preparing to divide, the DNA of the chromosomes is stored in a loose, uncoiled state so that transcription and other processes can more easily take place. This loose mixture of DNA and proteins is called:

• Chromatin

• Chromoplasm

• RNA

• Nucleus juice

Most eukaryotic genomes have their genes split between several very large molecules of DNA. These large molecules of DNA are called:

• Chromosomes

• Chromatins

• Centrosomes

• Centromeres

Most eukaryotic organisms will inherit two copies of each of their chromosomes, one from their father (paternal) and one from their mother (maternal). Two copies of a chromosome together make a:

• Homologous pair

• Synonymous pair

• Chromosomal pair

• Cellular pair

The two copies of each chromosome that are formed after DNA replication occurs are known as:

• Sister chromatids

• Homologous chromosomes

• Homologous chromatids

• Sister nucleotides

The centrosome is an organelle that:

• Acts as the microtubule organizing center that will produce and coordinate the microtubules necessary for the events of cell division

• Stores the DNA until a cell is ready to divide

• Produces the ATP necessary for division to occur

• Produces new chromosomes

During which phase of the cell cycle does DNA replication occur?

• S

• G1

• G2

• M

Prokaryotes divide using a process known as:

• Binary fission

• Cytoplasm splitting

• Mitosis

• Binary fusion

Mitosis produces:

• 2 genetically identical daughter cells

• 4 genetically identical daughter cells

• 2 genetically unique daughter cells

• 4 genetically unique daughter cells

• 4 genetically identical daughter cells

• 2 genetically unique daughter cells

• 4 genetically unique daughter cells
