Mitosis - Stages of Mitosis | Cells | Biology | FuseSchool

In this video we are will look at mitosis, including the names of the key stages: interphase, prophase, metaphase, anaphase, telophase and cytokinesis.

Mitosis is the process of cell division that produces identical copies of cells, and is involved in growth, cell repair and asexual reproduction. When cells divide by mitosis, the number of cells increases, and hence the organism grows.

Different organisms have different numbers of chromosomes. A chromosome is made up of two chromatids; one from the mother and one from the father.

During interphase, the chromosomes duplicate and become two identical chromatids, joined at the centromere. So in humans, it has gone from the normal 46 to 92.

During prophase, the chromosomes condense in the nucleus, and the spindle fibres form in the cytoplasm.

During metaphase the nuclear membrane breaks apart, the spindle fibres attach to the chromosomes and the chromosomes line up at the equator of the cell.

In anaphase, the spindle fibres shorten and the centromere divides, so that each chromosome becomes two separate chromatids.

During telophase the nuclear membrane forms around each set of chromosomes. The chromosomes spread back out in their ‘new’ nucleus and the spindle fibres break down. In humans, each nucleus has the normal ‘46’ chromosomes again.

The final stage is cytokinesis. The cell membrane pinches in to separate the two sets of chromatids into two identical daughter cells, with the same number of chromosomes as the parent - so 46 (or 23 pairs) in humans.

Dude this just explained my hour long lecture of notes in 3 minutes lol

[Batman.-]

Funny how 5 lessons at school and i don't understand anything, and then a simple 3 minute video and I finally get it

[Science-Made-Easy]

Keep it up Fuse School ! You saved me 2 hours of research and explained everything in just a few minutes !

[ejayj]

Best video I could find on all of YouTube. Cut, clear, and straight to the point.

[retrothecake]

Who else is watching this in quarantine for school

Just me...

You need to double-check your wording of sister chromatids. Sister chromatids are identical pieces of DNA from the SAME organisms, not from two different parents. Homologous chromosomes are similar strands of DNA, one from mother, one from father.

Hopefully this will let me pull through my science test about mitosis and meiosis... it's in about 12 hours lmao I haven't studied

[jrobin]

thank u sm i legit forgot the stages and how to explain them, this was really simple but useful, tysm

[patrickdaugherty]

The chromosome NEVER goes from 46 to 92 chromosomes. It goes from 46 single chromosomes to 46 double chromosomes. The genetic information between the two sister chromatids is the exact same so it does not count as another chromosome. I just had to stop this video because I do not want my students to be confused.

[fernandacarolina]

lets hope and pray this video helps me pass my genetic portion of my biology exam

[leverg]

I love your video sm, thank you for the help :D. plus, I like the animated educational videos better than the regular videos, I don't know why I like them more but they help me understand faster and better than regular videos which are not animated. Keep on making more of this, thank you so much it really helps. Sending you loads of love <33

This is an inaccurate video; at 1:06 he says that is a pair of chromosomes. It is not; it is one duplicated chromosome. He says one chromatid came from mom and the other came from dad within the one chromosome. This is also inaccurate; they are identical. This is coming from a biology teacher.

[franciscafadairo]

Thank you for making this so clear. I finally get it😌

[hazgaming]

This covers everything in mitosis on my spec thanks.

[AliHussain-uhxt]

basically when interphase happens everything in the cell doubles which are mitochondria ribosomes chromosomes then once doubled, prophase is when the spindal fibres come in and then metaphase is when the nuclei membrane disappears and the spindal fibres connect with the chromosomes anaphase is when the spindal fibres shorten and split the chromosomes telophase is when the nuclei membrane form around both the two chromosomes and finally cytokinesis is when both the nuclei push in opposite directions so the cytoplasm splits up to make the identical cells

[petertan]

Just note that Mitosis isn't used for cell repair but for tissue repair 0:35

[AbsoluteFilth]

This is funny, because I have been studying my textbook for a week and couldn't understand much, but this 3 minute video made me understand it .

[abrahamsolomon]

You can remember the phases by the mnemonic IPMAT: "I passed my anatomy test".

[matacubofamily]

thankyou so much! It helps my daughter to her powerpoint video thanks!

[abaeta]

Thanks so much man! I have a bio exam tomorrow and really needed help understanding this.
