Mitosis and Meiosis

Choose the three statements of the cell theory

• All organisms are made of one or more cells

• The cell is the basic unit of all organisms

• All cells come from existing cells

Name the phase:

• Prophase
• Metaphase
• Anaphase
• Telophase

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.

Name the phase:

• Prophase
• Metaphase
• Anaphase
• Telophase

Name the previous phase.

• Prophase
• Metaphase
• Anaphase
• Telophase

Making a copy of DNA in the cells is called ___.

• DNA revision

• DNA replication

• DNA transmutation

Name the phase:

• Anaphase
• Telophase
• Metaphase
• Prophase

WHAT DOES MEIOSIS CREATE?

• CHROMOSOMES

• GAMETES

• DNA

• TRAITS

MEIOSIS IS NEEDED BECAUSE...

• IT ACTUALLY ISN'T, BUT CAN BE HELPFUL IN SOME ORGANISMS

• TO REDUCE THE CHROMOSOME NUMBER BY HALF

• SO THAT EVERY CELL IS EXACTLY IDENTICAL

• TO MAKE SURE EVERY HUMAN CELL HAS 92 CHROMOSOMES

THE END RESULT OF MEIOSIS IS...

• FOUR UNIDENTICAL GAMETES

• FOUR IDENTICAL GAMETES

• TWO IDENTICAL GAMETES

• TWO UNIDENTICAL GAMETES
