Study Skills: Answer the following questions, and watch the video attached to the following link: http://www.pbslearningmedia.org/resource/tdc02.sci.life.stru.dnadivide/mitosis/
Directions: Mitosis is one stage in the mitotic phase of the cell cycle. Mitosis is divided into four parts. Read each sentence and decide which part of mitosis it describes. On each line, write the term
from the word bank that correctly matches each sentence. Terms will be used more than once.
anaphase
metaphase
prophase
telophase
1. Duplicated chromosomes align along the middle of the cell.
2. The cell begins to get longer.
3. Duplicated chromatin coils together tightly.
4. Sister chromatids in each duplicated chromosome separate and are pulled in opposite
directions by the spindle fibers.
5. The nucleolus disappears, the nuclear membrane breaks down, and spindle fibers form
in the cytoplasm.
6. A nuclear membrane grows around each set of chromosomes.
7. Spindle fibers that helped divide the chromosome begin to disappear, and
chromosomes begin to uncoil.
8. Spindle fibers pull and push the duplicated mitotic chromosomes to the middle of the
cell.
9. Two new identical nuclei are formed.
10. Two identical sets of chromosomes are at opposite ends of the cell.
Directions: Answer each question on the lines provided.
11. What are the two cell division stages in the mitotic phase of the cell cycle?
12. What happens during cytokinesis?
