mRNA Translation (Advanced)
The job of the mRNA is to carry the gene's message from the DNA out of the nucleus to a ribosome for production of the particular protein that this gene codes for.
Originally created for DNA Interactive ( http://www.dnai.org ).
TRANSCRIPT: The job of this mRNA is to carry the genes message from the DNA out of the nuceus to a ribosome for production of the particular protein that this gene codes for. There can be several million ribosomes in a typical eukaryotic cell these complex catalytic machines use the mrna copy of the genetic information to assemble amino acid building blokes into the three dimensional proteins that are essential for life. Lets see how it works. The ribosome is composed of one large and one small sub-unit that assemble around the messenger RNA, which then passes through the ribosome like a computer tape. The amino acid building blocks (that's the small glowing red molecules) are carried into the ribosome attached to specific transfer RNAs. That's the larger green molecules also referred to as tRNA. The small sub-unit of the ribosome positions the mRNA so that it can be read in groups of three letters known as a codon. Each codon on the mRNA matches a corresponding anti-codon on the base of a transfer RNA molecule.The larger sub-unit of the ribosome removes each amino acid and join it onto the growing protein chain. As the mRNA is ratcheted through the ribosome, the mRNA sequence is translated into an amino acid sequence. There are three locations inside the ribosome, designated the A-site, the P-site and the E-site. The addition of each amino acid is a three step cycle: First, the tRNA enters the ribosome at the A-site and is tested for a codon/anti-codon match with the mRNA. Next, provided there is a correct match, the tRNA is shifted to the P-site and the amino acid it carries is added to the end of the amino acid chain. The mRNA is also ratcheted on three nucleotides or one codon. Thirdly, the spent tRNA is moved to the E-site and then ejected from the ribosome to be recycled. As the protein synthesis proceeds, the finished chain emerges from the ribosome. It folds up into a precise shape, determined by the exact order of amino acids. Thus the Central Dogma explains how the four letter DNA code is - quite literally - turned into flesh and blood.
Powering the Cell: Mitochondria
Together Harvard University and XVIVO developed this 3D animation journey for Harvard's undergraduate Molecular and Cellular Biology students about the microscopic world of mitochondria. The animation highlights the creation of Adenosine Triphosphate (ATP) -- mobile molecules which store chemical energy derived from the breakdown of carbon-based food. ATP molecules act as a kind of currency, imparting chemical energy to power all the functional components of cellular activity. This piece is the second in a series of award winning animations XVIVO is creating for Harvard's educational website BioVisions at Harvard. The first program, Inner Life of the Cell, received international acclaim and can be seen both on our website and the BioVisions site.
Cells Cells - Parts of the Cell Rap
This rap was created for a 6th grade science classroom to teach about the different parts of a cell. With its catchy rhythm and rhymes, students of all learning styles and abilities will be able to learn about cells and their functions while having fun!
Original Rap by Ms. Quitmeyer
Today's the day were gonna learn about the cell
If I teach it okay, you'll know it very well
So listen up 6th graders-
-no room left for haters-
lets talk about the building blocks of life- cells that make us.
Cells, cells they're made of organelles
Try to pull a fast one, the cytoplasm gels
The nucleus takes over controllin' everything
The party don't stop 'till the membrane blocks the scene
Inside the vacuole we can float around for hours
Running round with chloroplasts, lovin' sunlight showers
Cells, cells, they're made of organelles
First things first, there's two different types-
animal and plant cells that make up all life.
The little things that make up microscopic cells,
The main structures- yeah, we call them organelles.
Now let's break it down and get some information-
How do cells work? It's a crazy combination!
The cell membrane is the border patrol,
Who can cross over? The membrane lets 'em know
The gooey stuff inside, is called the cytoplasm
It holds the organelles- don't worry, plasm-has 'em!
In the middle of the cell you'll find the big brain,
The nucleus surrounded by nuclear membrane
Don't forget the vacuole filled up with water
It's a basic need for life when this rap keeps getting hotter!
The mitchondria's something every cell needs,
Breaking down the food and releasin' energy.
There's a place inside the cell where chemicals are stored, the squiggly golgi bodies, releasin' even more.
Yo hangin' in the cell is endoplasmic reticulum, synthesizin' enzymes for respiration, and um...
If you still think that this rap is whack, remember ribosomes making proteins gettin' jacked!
Lookin at the plant cell, weird and green
two more parts is all it takes you see?
Cell wall knows what's up when it comes to keepin' structure
Strong with cellulose, this cell can't get much tougher.
C-H- L-O- R-O -- Plast,
These little green machines are havin' a blast
Photosythenisizing- filled with chlorophyll
-they hit the cell club, runnin' up a high bill-

Journey Inside The Cell
http://www.discovery.org This animation shows how the digital information encoded in DNA directs protein synthesis inside the cell and provides a unique look at the evidence for intelligent design as described in Dr. Stephen C. Meyers book Signature in the Cell. For more information visit http://www.signatureinthecell.com
The Stages of Mitosis
Stages of Mitosis, a promotional piece, begins with a fly-through of cells preparing to undergo mitosis (cell division).
Upon entering a cell we are introduced to various organelles of the inner cell and the key events involved in mitosis.
Cell division involves 7 key stages resulting in the splitting of the nucleus, and ultimately, cell division.
This animation shows the dynamics of the golgi apparatus, a subcellular organelle involved in protein export. Proteins being processed for export are shuttled in vesicles between the membranous layers.
Golgi Apparatus - an animatic
Golgi Apparatus - the function is to process and package the macromolecules that are synthesized by the cell for processing of proteins for secretion.

Question from the comments:
I was wondering how cells know where they are in our bodies. Like how does a cell know if its supposed to be a cell for the surface of our skin, a brain cell, a muscle cell, etc? What makes a new cell thats growing the middle of a muscle know that it's supposed to be a muscle cell, rather than a dif type?
Great question! It has everything to do with the signals cells receive from other cells and what stage of development you are talking about - embryo or human.
