DNA Transcription (Basic)

Transcription is the process by which the information in DNA is copied into messenger RNA (mRNA) for protein production.

TRANSCRIPT: What you are about to see is DNA's most extraordinary secret — how a simple code is turned into flesh and blood. It begins with a bundle of factors assembling at the start of a gene. A gene is simply a length of DNA instructions stretching away to the left. The assembled factors trigger the first phase of the process, reading off the information that will be needed to make the protein. Everything is ready to roll: three, two, one, GO! The blue molecule racing along the DNA is reading the gene. It's unzipping the double helix, and copying one of the two strands. The yellow chain snaking out of the top is a copy of the genetic message and it's made of a close chemical cousin of DNA called RNA. The building blocks to make the RNA enter through an intake hole. They are matched to the DNA - letter by letter - to copy the As, Cs, Ts and Gs of the gene. The only difference is that in the RNA copy, the letter T is replaced with a closely related building block known as "U". You are watching this process - called transcription - in real time. It's happening right now in almost every cell in your body.

THis was all worth it for th e 3-2-1- GO !! NIce

@BigD71889 Let's start an Atheist Rant because mistakes of the DNA is what caused Humans to evolve as Primates.....

Nah, i'm just trolling.

@nflhester3 hear hear, i hope they have a "transcription for dummies" version ;D

[Lucky10279]

thsi is creepy, but cool

[nflhester3]

i cant believe they mentioned RNA in a "basic" video, save that for the advanced lecture!!

[hotshit57ify]

This shit is fucking gay im going to watch a fight fuck this shit

[DUKEOFNUTS99]

balls

[DUKEOFNUTS99]

this vid sucks



[Jeannene97]

ha this shit was so fucking dope:) Aka.. Anthonyyyy (:

@artemistziolis Technically it was a mistake that caused us to split from normal primates, but it was a good mistake lol. And it allowed the early human with that gene (or genes) to reproduce and pass it on, and through natural selection favoring the early humans with that specific gene combination tada the first offical member of the homo genus

@papasmurfXXX Ok ill bite, in the simplified form thats exactly what happened, but actually there are multiple ways to mutate and that does not drive evolution, what drives it is natural selection, which will favor a mutation that helps the species survive and reproduce

[artemistziolis]

@papasmurfXXX humans evolved as primates because of a MISTAKE in the DNA?

no, that was evolution. mutation in the DNA, yes, but no, not a mistake.
