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!

⁣An idiom is a phrase that is common to a certain population. It is typically figurative and usually is not understandable based solely on the words within the phrase. A prior understanding of its usage is usually necessary. Idioms are crucial to the progression of language.

⁣A verb is a word that indicates a physical action (e.g., “drive”), a mental action (e.g., “think”), or a state of being (e.g., “exist”). Every sentence contains a verb. Verbs are almost always used along with a noun or pronoun to describe what the noun or pronoun is doing. ⁣A tense is a form of the verb that allows you to express time. The tense of the verb tells us when an event or something existed or when a person did something.

⁣Cursive (also known as script, among other names) is any style of penmanship in which characters are written joined in a flowing manner, generally for the purpose of making writing faster, in contrast to block letters.

Trade Unions paly an important role in our economy. In this lesson Mr Du Plessis teaches us why trade unions are important, when and why they started and how it effects our economy.

⁣Perfect verb tense is used to show an action that is complete and finished, or perfected. This tense is expressed by adding one of the auxiliary verbs — have, has, or had — to the past participle form of the main verb. For example: I have seen the movie that was nominated for an Academy Award.

⁣A synonym is a word that has the same meaning as another word (or nearly the same meaning). For example, beautiful and attractive are synonyms of each other because they both refer to someone or something that looks good.

⁣Water pollution is the contamination of water sources by substances which make the water unusable for drinking, cooking, cleaning, swimming, and other activities. Pollutants include chemicals, trash, bacteria, and parasites. All forms of pollution eventually make their way to water.

⁣The EPA defines environmental waste as “an unnecessary use of resources or a substance released to the air, water, or land that could harm human health or the environment.” This can include anything from construction materials to food scraps and everything in between.

⁣Weather affects everyone and everything it its path, beginning with the clothes you put on to meet your day to the type of outdoor activities you choose to engage in. Weather impacts human, animal and plant health, as well as the food supply, and it contributes to the average climate in your area.

⁣The materials are tested using accelerated aging methods. Stabilizing additives may be used to prolong the useful life of the materials. An array of analytical methods is being used to monitor changes during aging, and finally conservators judge the products for handling and appearance.

⁣Mixtures can be separated using a variety of techniques. · Chromatography involves solvent separation on a solid medium.

⁣The number denotes whether we speak of one object or more. Singular Number- A Noun that denotes one person or thing is said to be in the singular number; as, man, boy, girl, bird, etc.

⁣SKIMMING & SCANNING. Skimming and scanning are reading techniques that use rapid eye movement and keywords to move quickly through text for slightly different purposes. Skimming is reading rapidly in order to get a general overview of the material. Scanning is reading rapidly in order to find specific facts.

How to Draw Graffiti Letters - Jack in graffiti lettering with a drop shadow and an outline. Graffiti style lettering flows and connects in interesting ways. Determining how these letters connect and flow is part of the creative process of designing graffiti letters. In this demonstration you will see some of the creative choices and creative struggles faced in creating this design.

Look for ways to create symmetry in your graffiti name designs. In this design I look for ways to balance the feel of the Letter J against the letter K. This design includes a drop shadow, a border or outline and coloring. Learning to draw graffiti style lettering is an ongoing process of observation and experimentation.
