The mitosis slides are located in the second back room. They can be a challenge to look at. If they can be found then your teacher will assist you in observing these prepared slides .
Draw mitosis under high power in the light microscope in 3 pictures. Label the stages of mitosis

steps of cell cycle: you should write a table showing the steps as well as the
FORM OF DNA
role of other organelles
1. INTERPHASE -
a. cell is undergoing growth. After a period of growth, it prepares to divide
b. cell replicates its DNA. Nuclear membrane is still intact
2. PROPHASE
Nuclear membrane disappears and the chromosomes are visible
3. METAPHASE
chromosomes line up in the middle and Centrioles send out the spindle fibres to attach to the centromere
4. ANAPHASE
centromeres get ripped apart and thus the chromosomes get ripped apart into separate chromatids
5. TELOPHASE
nuclear membrane reforms around the chromatids
6. CYTOKINESIS
chromatin is in the nucleus now.
Watch all three videos on DNA replication. Start with my lecture video. Your online quiz on friday will include this content!
This DNA replication Song was made by my students in 2007. They were grade 11 students taking my bio 12 course. Their music teacher is the same as your band teacher now.
Assignment : Answer the following questions in a creative format
1. Why does DNA replication happen? Give three reasons
2. a. Draw a nucleotide and identify the 5' end and the 3' end
b. draw a DNA ladder structure and label the 5' and 3 ' end
3. Compare and contrast DNA and RNA.
a. What are they made of?
b. What are their nitrogen bases?
c. What enzymes synthesize DNA and RNA?
d. How does DNA polymerase join one nucleotide with another nucleotide?
4. What are the main steps of DNA Replication. Include details of what each enzyme does
a. Helicase
b. Primase
c. DNA pol III
d. exonuclease
e. DNA pol I
f. ligase
