SUMMARY: This video teaches about the process of mitosis. Mitosis is a process of cell division where a single cell divides to produce two genetically identical daughter cells, each with the same number of chromosomes as the parent cell. It consists of several stages—prophase, metaphase, anaphase, and telophase—followed by cytokinesis, ensuring equal distribution of chromosomes to each new cell.

LYRICS
Interphase is cell division's longest part,
nuclear membrane's intact as it starts,
The cell's growing, cytoplasm flowing,
chromosomes get duplicated, DNA gets replicated

Chromosomes are spread out so they can't be seen distinctly
But note the nucleolus, the ribosome factory
Outside the nucleus are two centrosomes,
They later make a spindle which will pull apart the chromosomes.

Prophase follows, the chromosomes condense,
Each is made of two sister chromatids, (looks) like an "X"
Each sister is a clone, the closest of kin,
And a centromere connects them like siamese twins,

The nucleolus disappears it melts away,
as the cell takes a ribosome production holiday,
the centrosomes separate, start spindle formation
for separating chromatids and cell elongation.

CHORUS
Mitosis, chromosomal ride
Inter-, pro-, meta-, ana-, telophase, divide
Eukaryotes go from one cell to two,
Mitosis, how cells renew.

In late prophase --prometaphase,
The nuclear membrane disintegrates,
The centrosomes migrate to the cell's opposing sides,
And between them the fibers of the spindle wend and wind,

The spindle's made of microtubule fibers which attach
to chromosomes at kinetochores, a protein patch
that serves like a handle that the fibers can grasp,
When they pull apart the chromosomes, splitting them in half,

The spindle moves the chromosomes with nudges so fine,
Into linear formation on the 50 yard line
A location equatorial defining metaphase,
where the chromosomes are lined up on that middle place

CHORUS

The spindle fibers pull on the kinetochores,
A cellular molecular mitotic tug of war,
The centromere snaps, sisters get separated,
Now these chromatids are chromosomes, they've been upgraded

This snapping separation defines anaphase
The "A" for "apartness", for moving different ways,
Kinetochore spindle fibers separate the sisters
See 'em waving goodbye, calling out "I'm gonna miss ya,"

And the other spindle fibers push and grapple like felons
Makes the cell elliptical like a watermelon,
In telophase membranes form 'round the chromosomes
Which spread out as the nucleoli come on home

CHORUS

In animal cells there's a ring of micofilaments
that form at the equator and they cinch themselves in
Tighter, tighter, tighter, tighter 'til the cell is in two pieces,
Yeah in animals, that's cytokinesis

But it's different in plants in them the cell divides
By building a new cell wall from the inside
As the Golgi sends vesicles with cellulosic goo,
Which makes a plate, then a wall, divides the cell in two

And instead of one mother cell we now have daughters two
Identical twins, kind of old but kind of new,
From your single celled beginning this is how you grew
And for single celled eukaryotes it's reproductive too!

This is 'Chromosome', the educational parody of Lady Gaga's 'Telephone' music video. It is a project that I directed this summer in the hopes of making science fun and interesting for students. Thank you to all of my talented friends for helping make this video possible! I hope you enjoy it and remember everyone, science is fun!

Lyrics:
Hello? Hello? Baby, you called. I can't hear a thing.
I have got not service in the laboratory.
I have got no time for talking. Baby, can't you see?
I am trying to study some biochemistry.

When the chromosomes condense then we call it prophase.
And when they line up then it is called metaphase.
When they pull apart then we call it anaphase.
And when they divide into two cells that is telophase.

Stop calling. Stop calling. I don't wanna talk anymore.
I have a test that I am studying for.

DNA wrapped around histones.
It's all in the chromosome.
Everything in your genome:
It's all in the chromosome.

And when those cells explode they call it apoptosis.
Different than necrosis. Not caused by osmosis.
It's dangerous when the cell begin undergoing anoikis.
Then there's metastasis. Cell death is so tasteless.

DNA is simple if at first you only think,
That you have a purine paired with a pyrimidine.
The sugar-phosphate backbone holds all the bases
Which is twisted around like a spiral staircase.

Copying, copying like in vivo but much faster.
I got my genes from the lab thermocycler.

The Cell Theory Song
Mr. Tamez

Lyrics:

CHORUS
All living things are composed of cells
Cells are the basic units of structure and function in living things
New cells are produced from existing cells

VERSE 1
Back then was a guy named Hooke, cut some cork and he had a look
Underneath his microscope tiny rooms that he saw in groups
Empty rooms that looked like shells He's the one that called them cells
Listen up cause we're not done Cell theory had just begun
Add one scientist to know the inventor of the microscope
Anton von Leeuwenhoek saw cells move and he was like "That's dope"

PRE CHORUS
Cell theory, cell theory, cell theory, cell theory, cell theory, go!

VERSE 2
If you thought this was complete take a breath and have a seat
Two scientists to have their say Schleiden and Schwann to save the day
Schleiden said all plants have cells they are alive and we can tell
The next year Mr. Schwann could see all animals have cells that live and breathe
Oh they live and breathe Live and breathe

BRIDGE
In 1855, Rudolph Virchow proposed that all cells
Come from other cells
This was the final discovery
That ended cell theory cell theory

What is Mathematics? Explained using animations and illustration Video.

⁣Meiosis is a type of cell division in sexually reproducing organisms that reduces the number of chromosomes in gametes (the sex cells, or egg and sperm). In humans, body (or somatic) cells are diploid, containing two sets of chromosomes (one from each parent).

⁣In order for a sentence to be grammatically correct, the subject and verb must both be singular or plural. In other words, the subject and verb must agree with one another in their tense. If the subject is in plural form, the verb should also be in plur al form (and vice versa).

About us:
Welcome to Tutway.
A unique platform where learning is fun.
Now there is no distinction between kids’ fun time and study time.
At Tutway, we believe in a very simple idea that audio-visual learning is the most effective tool for grasping knowledge. Many researchers have proven that kids learn a lot by playing interactive games and watching audio-visual animated lessons as compared to reading from books.

That's when Tutway comes to the rescue.
Tutway is a supplementary education program where kids can learn at their own pace. The students can watch animated videos that are so meticulously made that they can understand even the most complex concepts very easily. There is a question bank at the end of each video where students can answer those questions multiple times and test whether they have grasped knowledge completely or not.
We have information systems embedded in the program where parents can monitor real-time performance of their kids and get up to date information about their performance, including quizzes attempted and the marks got in each quiz, both in tabular and graphical formats. Regular reports are e-mailed to the parents so that the parents can analyze their kids’ performance.
If we want to learn high-level concepts, we should have a clear understanding of the basic concepts. For instance, if kids don't know about addition and subtraction, they cannot do multiplication, and if they don't know about multiplication, they cannot do division, and if they don't have knowledge of these four basic operations, Algebra cannot be done by them, and it goes on and on.
The same applies to the English language if kids don't have sound knowledge of grammar and vocabulary; it becomes extremely difficult for them to have their communication skills.
Knowledge of the scientific concepts is also required for observing physical, chemical, biological phenomena happening all around us.
That is why; Tutway has thousands of animated videos on Maths, English, and Science to clear the basics of these subjects. It perfectly suits most of the educational needs of most of the students, regardless of their learning abilities.
So hurry up, download the Tutway app and book a free-demo cl**** to make education interactive and fun experience.
