Mitosis and Meiosis Simulation

Mr. Andersen uses chromosome beads to simulate both mitosis and meiosis. A brief discussion of gamete formation is also included.

Where did you purchase the models you use in your simulation?

QUEStion- do the organelles double at G2 or something? Cuz if they dont each new cell will have a wierd number of different organelles, right??

[bozemanbiology]

@sosweetss57 Great question. Organelles like the mitochondria and chloroplast will duplicate independently throughout the cell cycle. They have their own DNA and act autonomously. The other organelles can be constructed in the cell. After cytokinesis a cell will have fewer organelles in each half but they will quickly return to normal during Interphase.

hey i just want to point out a mistake: you make it sound like the spindle fibers form INSIDE the nucleus; you need to specify the the centrosomes and the mitotic spindle form outside the nucleus, whose membrane disintegrates during prometaphase

@killergoku56 Thanks. I added a caption during the video that points out my error.

Totally wish you were my prof!!!

Always love your videos! :) Thank you so much!

THE CHOSEN ONE!! :D this is so helpful

@Haileymorgann That's it. Once you undergo meiosis and become a gamete (ie sperm or egg) you don't undergo any divisions till you fuse with another gamete to form a zygote with diploid chromosome number. Then you undergo mitosis to become an embryo, and a fetus from there. Hope that helps! :)

you should become a teacher. you would be making the employment rating increase considerably

lol "the chosen one"

goood video :) thanks for sharing

thnx for saving my test

I didn’t realize how poor my teacher was teaching until you explained this. Thank you! Question: When a cell undergoes meiosis and the cell splits into four others with half the number of chromosomes they split from, do the divided cells undergo meiosis again or is that it for them? Because it seems like if a cell keeps dividing its chromosomes, pretty soon it will run out of chromosomes to divide.
