Opening Credits.

PITCH BLACK:

The slow and mesmerising soundtrack begins.

FADE IN and ZOOMinto a glowing object from the distance.

Narrator (V.O.)

Cells. There are 10 trillion cells that make up a human body. Each cell

contains DNA, deoxyribonucleic acid, which is the genetic information

necessary for controlling all cellular activities. There are two main types

of cells called the eukaryotic cell and the prokaryotic cell.

Most eukaryotic cells follow a process of growth and division called the cell

cycle. The cell cycle has 2 key stages, interphase and the Mitotic Phase. The

interphase consists of G1, S and G2. In the G1 stage normal cell functions

occur and growth begins. In the S stage DNA synthesis occurs, making two

copies of chromosomes. G2 prepares the cell for Mitosis in which the

chromosomes will divide into two genetically identical cells.

LONG SHOT one single cell is rotating and pulsing slowly.

CLOSE UP and PAN passing through the cell portraying the cells inner

structure, before exiting through the opposing side.

BACKGROUND slowly transforms from a pitch black into an array of blurred

blues, purples and turquoises.

CAMERA LENSE FOCUSING hundreds of cells can be seen drifting and pulsing

through the confined inner space.

CAMERA MOVEMENTremains

STILL, focusing on the movement of the cells.

ZOOM INTO cell and pass through the opposing side of the cell, blurring the

surrounding cells into colours and glows/lights.

Narration (V.O.)

Once the cell is ready Mitosis occurs. Mitosis has 4 major phases; Prophase,

Metaphase, Anaphase and Telophase.

In the first phase, Prophase, Chromosomes become more visible and condense

becoming shorter and thicker. Each single copy of the chromosome is called a

sister chromatid and they exist in the nuclear envelopes. The nuclear

envelope breaks down. Spindle fibres form as microtubules grow out of

centrioles. The centrioles then progress to opposite poles of the cell.

In the next phase, Metaphase, the double stranded Chromosomes line up along

the equator of the cell preparing to divide. At this moment the spindle fibre

is fully formed and attached to the microtubules and each individual sister

chromatids.

In Anaphase the Chromosomes are divided and move away via its spindle fibre.

In the fourth and final phase in Mitosis, Telophase, the Chromosomes reach

the opposite end of the cell and develop a new nuclear envelope around the

chromosomes. It is now when the chromosomes uncoil and the spindle vanishes.

MS, CU, XCU, CAMERA ROTATES, PANS, ZOOMS accordingly to the process of the

cell cycle and mitosis.

Narration (V.O.)

Finally when Cytokinesis occurs the cytoplasm separates and the cells divide

into two genetically identical structures. Cell division is complete.

The cells slowly separate and remain still.

MS. CAMERAremains STILL, focusing on the two separated cells and their

movement.

PANS OUT slowly and the frame begins to fill with pulsing/drifting cells.

FULL ZOOM OUT millions of cells can be seen; the lighting is shimmered across

the cells.

FADES TO BLACK.
