The begining of the video concentrates on how a cell maintains its structure (eg. Intermediate filaments) and the extracelluar matrix. Followed by the behaviour of microtubles (structure that forms on one end and degrades at the other), to which you see kinesins travel ("walk") on, while carrying a vesicle as it heads towards the Golgi Apparatus (GA). Then, in the ER and cytosol, there is DNA transcription and translation, where the products are put into vesicles. Vesicles arrive at the GA. Then, you see the vesicles traveling towards the plasma membrane, away from GA. When it reaches the PM, the vesicle releases the products. The video ends with a macrophage (wbc) going through a barrier of infected epithelial cells. It "flattens" right before entering the barrier because the infected cells express receptors and ligands (cytokines/chemokines) that increases the wbc's affinity to the site of infection.

One thing to ... ( 2 weeks ago by fimblemccrumblewitz)

One thing to remember about this video is that it's an animation and not a simulation, so it will give the impression of a directed and highly controlled process, whereas the processes that are actually occurring in a cell are more random. For instance, the polymerization of the microfilaments at 0:53 would be mediated by an enzyme and would happen more or less as actin monomers randomly smashed into the enzyme. However, that would not be as much fun to watch and would take ten times longer.

So they are ... ( 2 weeks ago by gettuff2)

So they are randomly producing the desired effect??

Yes. How fast the process goes would depend on the cytosolic (the cell interior) concentration of actin monomers (the pieces that make up the long chain). The higher the concentration, the more likely a monomer would associate with the actin lengthening enzyme in a given peirod of time, thus occurring faster. The monomer doesn't "know" where to go, rather it floats around until it associates with the proper enzyme/protein or is degraded. Enzyme kinetics is fun.

And the purpose of the DNA strand in this random effect is?

Actin monomers ... ( 2 weeks ago by fimblemccrumblewitz)

Actin monomers would be produced by ribosomes via mRNA, which would be produced from some internal or external signal via the cell's DNA. The same goes for the enzymes that are responsible for building and destroying the microfilaments. These signaling events would cause a cascade of responses that ultimately lead to the transcription of the mRNA and the translation of the mRNA into a protein. There is a degree of control, but ultimately it's not as organized or as controlled as in the video.

I mean the fact, ... ( 2 weeks ago by gettuff2)

I mean the fact, according to the so called scientists, that the DNA strand is nothing but information.

It is how genetic ... ( 2 weeks ago by fimblemccrumblewitz)

It is how genetic information is stored and passed down from generation to generation, but other then that, I don't follow what you mean. Are you proposing some other function for DNA? If so, I know of no alternate functions to DNA.

At this point ask ... ( 2 weeks ago by gettuff2)

At this point ask yourself how did "information" get there. It is apparent that information must be regarded as having a conscious beginning. If you ponder this point you may find what you are looking for.

It's not at all apparent, and depends entirely upon your operating definition of "information".
