meiosis and mitosis

why is meiosis better than mitosis

• genetic variation

• longer process

• 2 divisions

• 4 cells made

Which of the following is matched with its correct function? SELECT ALL THAT APPLY

• DNA Pol III - Removes RNA Primer and replaces it with newly synthesized DNA

• Primase - Synthesizes RNA Primers for replication

• Sliding Clamp - seals the gaps between Okazaki fragments to create a continuous strand

• Single Stranded Blinding Proteins (SSBPs) - Helps to hold the DNA polymerase in place when nucleotides are being added

Which of the following are CORRECT observations about the differences between MITOSIS and MEIOSIS? (Check all that apply.)

• Mitosis produces cells that identical to the parent cell.

• Meiosis produces cells that have half the number of chromosomes as the parent cell.

• All cells go through INTERPHASE as part of the cell cycle, whether it goes to mitosis or meiosis next.

• In both types of cell division, the chromosomes are only duplicated once.

• Only in Mitosis, do you see chromosomes pair up to form a tetrad. (homologous chromosomes)

Check all of the following that DO occur during Telophase I and cytokinesis. SELECT ALL THAT APPLY

• The separated homologous chromosomes are at opposite poles of the cell.

• The cell divides in two.

• The chromosomes do not uncoil, since they are getting ready for Meiosis II.

• Sister chromatids are pulled away from each other.

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.

Chromosomes are duplicated during what stage of the cell cycle?

• G1 Phase

• S Phase

• Prophase

• Prometaphase

Fruit fly body cells have 8 chromosomes. After mitosis, you would expect a resulting fruit fly daughter cell to have -

• 16 chromosomes.
• 46 chromosomes.
• 8 chromosomes.
• 4 chromosomes.
