Your genome, every human's genome, consists of a unique DNA sequence of A's, T's, C's and G's that tell your cells how to operate. Thanks to technological advances, scientists are now able to know the sequence of letters that makes up an individual genome relatively quickly and inexpensively. Mark J. Kiel takes an in-depth look at the science behind the sequence.
Lesson by Mark J. Kiel, animation by Marc Christoforidis.

@@omkarchavan5940 GATTACA portrayed a technology that can predict specific personalities and everything phenotypical (body characteristics that are observable) which was a predominant theory in the 20th century, known as biological determinism. However, as science advanced, the theory had became outmoded and invalid, primarily due to the current acceptable scientific view of the world which is stochastic. Moreover, we had found that protein-coding genes are at times, multifactorial and require the environment and social interactions to shape its function, which directly contradicted the ideologies put forth by GATTACA.

@TheyCallMeNewb
@TheyCallMeNewb 10 лет назад
I'm more than a little taken back. How can it be, that colour can be administered through an enzyme into the genome and photographed. Additionally, does this methodology for reading genome not assume that a base constituent can not bond with itself; Adenine and adenine for example?
@kanizbristy5425
@kanizbristy5425 3 года назад
Well, there are chemical reactions that produces colored compounds. That's what those enzymes do, they catalyze a reaction (e.g. break something down) to produce some colorful chemicals. That's the color part. And no, A and A or any of the other combinations usually don’t bond together because of their unique chemical properties. But yes, sometimes mistakes do happen. For that, a single sequence (the small parts mentioned here) is read more than a hundred times to ensure that those "by chance" interactions don't affect the final result.

no, we do not function from binary structure- and we are made up of different parts. Our brains do not function the same way, nor do our cells.

Humans do not work like computer programs, and even neural nets cannot function with the same braod complexity that we do.

@kanizbristy5425
@kanizbristy5425 3 года назад
Well, the binding of one nucleotide (the A,T,C and G) can only occur to a single strand after the previous one is added. Also, the pairs are constant. so where there is a T, nothing other than an A can bind. Very low chance of mistake. But of course, mistakes can and do happen. That's why a single sequence (the small parts mentioned in the video) is read more than a hundred times. So that those accidental mistakes don't affect the final result.

Hi, I have a question. Soat min 3.39 the narrator says that the pieces of DNA are stitched together. I'm assuming that this is done by the overlapping ends.. But could there not be errors where the ends might be overlapping but the mid parts are different? Wouldnt that cause wrong pieces to be stiched? Thanks. Newbie student
@wildlucifer
@wildlucifer 7 лет назад
Depending on what you are 'stitching' the genome together for. Just say you are sequencing another human genome to confirm the dissimilarities between them, they can always use a reference genome, aka an already sequenced human DNA, to help piece the DNA together. Now, no human DNA is the same but there will be massive similarities so you can still use that to help solve the problem you mentioned so as they do not fall in the wrong place. Also on another note, all those smaller pieces are different so it will be an overlap over an overlap over another overlap so it is not just an overlap of ending sequences. Another way to look at it is that these are more than billions of small fragments, or a shattered DNA, and not just 1 DNA but a pool of DNA of the same sequence. However, it is still not that perfect and needs to be sequenced enough times to get a solid answer before getting published. Third generation sequencers are trying to solve that problem, though. So instead of shattering DNA into smaller pieces, they can sequence the whole genome without breaking them up. It is still really pricey though.
