Mitosis

Cells can clone themselves.

Walther Flemming was the first to observe Mitosis.

The process of cells cloning themselves was named Mitosis by Walther Flemming.

Cells clone themselves to reproduce.


A cloned cell has half the power of a normal cell.

Lots of other microorganisms can clone themselves.


Bacteria uses Mitosis to spread around your body.

Mitosis is responsible for almost everything in your body.

The nucleus controls everything going on in the cell.

The nucleus splits into two when mitosis occurs.

Mitosis has lots of stages.

The new cells made by mitosis are called daughter cells.

The cell that makes the daughter cells is called the mother cell.

There can be errors in mitosis that can kill the cells or give you cancer.

Not all cancers are caused by mitosis errors.

The first stage of mitosis is called interphase.

The final stage is called cytokinesis.

Microtubules are protein ropes.

Metaphase means afterphase, and it is the longest phase of mitosis.

Anaphase is one of the stages in mitosis.

Ana means back.

Humans cannot be identical to their parents, but they can be identical to their brothers or sisters.

Almost every single one of the cells in your body can use mitosis.

Mitosis occurs about 10,000,000,000,000,000 times in your lifetime.

 There are some good reasons that you can't clone themselves.


Every singe one of eukaryotic cells can use mitosis.


Mitosis heals scars and cuts.


You get bigger because of mitosis.


It can take a long time for cells to finish mitosis.


Each sister cell has 46 chromosomes in them.


We don't know much about mitosis.


When using mitosis, lots of parts of the cell duplicate themselves.


The chromosomes do a lot in mitosis.


Walther Flemming was studying salamander skin when he discovered mitosis.


There are many questions left about mitosis.


On Anaphase the chromosomes pull back from each other.


Half of your DNA is from your mom, the other half from your dad.


Cells are using mitosis constantly all the time.


You are made of trillions of cells.


There are haploid cells, that only have 23 chromosomes in them.


Half of the chromosomes in your cells come from your mom, half from your dad.


The centrosomes duplicate when mitosis occurs.


At prophase, chromosomes start to look kinda like dreadlocks.


The place where the chromosomes meet is called the centromere.


Metaphase can take up to 20 minutes.

Metaphase is the longest phase.

You can watch mitosis through a microscope.


All living things are made of cells.

The Nucleus of a cell stores your DNA.

The Nucleus is the boss of the cell, telling the other parts of the cell what to do.

In Interphase, the Chromatin is messy and unarranged.

Mitosis was named after the greek word for thread.

The final stage of mitosis is telophase.

In telophase, the cells finally split.

Haploid cells are sex cells.

You only need to duplicate the DNA to use mitosis.

When the chromatin separates, they become chromosomes.

The latest contribution to the understanding of mitosis was given by a postdoctoral student named Tomomi Kiyomitsu.

Tomomi Kiyomitsu was studying Dynien, a type of motor protien, before he found out about what he discovered.

Tomomi Kiyomitsu figured out how Motor Protiens helps snap the chromosomes into line.

Tomomi Kiyomitsu's discovery was published very recently, in just February 2012, THIS YEAR.

In Metaphase, the chromosomes align in the middle of the cell.

TITIN!

The chemical name of Titin is 413 error

Snurps are a combination of RNA and proteins

Titin makes your muscles stretchy

The TATA Box helps the enzyme find the strand.

The chemical name of Titin is the longest word in english, but it isn't in the dictionary.

Titin is the longest protein.

The TATA box is nearly universal.

mRNA stands for Messenger RNA.

mRNA gets fed into the ribosomes in the Rough Endoplasmic Reticulum.

DNA

If you took a double helix from a cell and stretched it out, it would be taller than the average adult.

If you took all of the double helixes in your body and stretched them out end to end, they would reach the
Sun 600 times.

Nucleic Acid was called Nuclien.

DNA was discovered by Friedrich Miescher.

DNA's full name is Deoxyribonucleic Acid.

DNA is a type of Nucleic Acid.

Friedrich Miescher studied White Blood Cells.

Rosalind Franklin discovered the shape of DNA.

Rosalind Franklin wasn't alive to receive her Nobel Prize

DNA Is the most complicated molecule in the universe.

RNA, like DNA, is a Nucleic Acid

DNA Is called DNA because it includes Deoxyribose.

Photosynthesis

RuBisCo captures carbon dioxide

Plants create oxygen

All life is made out of chemicals

Plants have to produce lots of RuBisCo

Plants need sun, water and carbon dioxide to survive

A photon from the sun travels 93,000,000 miles to reach the earth.
