Your body is made of cells -- but how does a single cell know to become part of your nose, instead of your toes? The answer is in your body's instruction book: DNA. Joe Hanson compares DNA to a detailed manual for building a person out of cells -- with 46 chapters (chromosomes) and hundreds of thousands of pages covering every part of you.
Lesson by Joe Hanson, animation by Nipun.Co Motion Craft.

Hi, Joe here. I did the lesson! This is absolutely correct. The numbers referenced are for one copy of the genome, which is noted a couple of places in the animation, but should be made clearer. So the length, number of genes, etc. is actually double in any somatic cell.

The "induced pluripotent stem cells" that you may have heard about in the news are made essentially by doing this. They are given a set of artificial "switches" in the form of a few transcription factors that turn on a set of genes that makes a mature cell (like a skin cell) turn back into a stem cell.

@JoeHanson 11 жыл бұрын

Although each cell contains the same 20,000 or so genes, different cell types have different sets of switches that turn combinations of genes on or off. Most of these are transcription factors, which cause the cell to express a gene or not express a gene. Some of these signals come from chemicals that are flowing through your tissues like hormones and growth factors, and some of them come from neighboring cells. When you are developing in the womb, this is all carefully organized and regulated.

@martijnvanweele6204 10 жыл бұрын

***** not really...

@MichaelMcPartlin 10 жыл бұрын

Different gene regulations happen in each cell. In the early developmental stages, there is a gradient set up within the first cell and this leads to an unequal distribution of the different transcription factors, proteins, etc. within the first division. These transcription factors regulate specific genes so some genes are turned on and some are turned off. This determines the fate of the cell and subsequent replications and divisions tend to lead to similar cells. When there is a group of cells, they can communicate with one another to ensure that they are differentiating into similar cells.

@ChavitoPokemon 10 жыл бұрын

***** So, at a quantum level, these individual cells are aware of their fate and work together to ensure that their purpose does not differentiate from their peers? That's pretty interesting.. even cells have their own conscious.

@MichaelMcPartlin 10 жыл бұрын

ChavitoPokemon a single cell lacks a conscience as that is the product of multiple cells grouping together and establishing connections. I don't know if I would say the cells are aware of their own fate since you can rearrange the gradient during development to get different cell lines. This is commonly done in plants, but not done as frequently in animals. A conscience is one of things that nobody really knows too much about. Michio Kaku, a theoretical physicist, wrote a few books about his opinion on the matter. They are interesting reads.

Well, in light, the answer is quite an elongated one. The preposition that there are random elements is quite wrong. Natural selection works on existing elements which is refined with every generation. In the most simplistic terms, this process has developed over time because it is a "system" that allows variation for living entities to thrive and survive.
