Repairing DNA: Our Best Defense Against Cancer

Cancer occurs when a single cell in the body stops performing its normal function and grows out of control. Damage to DNA can lead to permanent changes, called mutations, which can result in cancerous growth. Lawrence Livermore National Laboratory scientist John Hinz explores how cells repair DNA, the consequences of unrepaired DNA damage, and the fates of individuals born without DNA repair proteins.

His presentation is really good, and very creative upset when he explains the risks of a damaged cell.

I had trouble creating that image myself just by reading a book.

A nice and a little bit funny video if you want to refresh your knowledge about DNA, cancer, and so on.

Thank you very much for sharing this, and I'm sorry for the rude comments you've recieved.

Some people live in a box and never gets out. They fear the truth of the world outside which is widly unknown to humans. Yet when they face knew knowledge they refuse its evidences by expressing meaningless hate to the people who've worked their whole life with it. They refuse it, because they want nothing to change, nothing to break their little imaginated bubble of happiness.

The world isn't like that, humans are mere survivors just like animals. If we don't keep thinking, we'll end up dead.

@omnissient The truth hurts doesn't it, you offer nothing intelligent,

your replies are boring, just like you! From your writing and thinking

'style', it is apparent that you lack normal 'instincts'.

You are a sad loser, who has no self esteem, wisdom, or insight!

You are teacher's little 'lad'....a loser, who sacrifices truth, for

acceptance. "Now go home and get your fuckin' shine box"

@omnissient I'd like to take off my belt and give you a whipping!

But unfortunately, I think you'd love it!

And I do know you ass face, you are the sad loser, who no one

appreciates, the serious student, who lived for his 'teachers'

approval. You'd be marching with the SS, if given the chance.

You are what is commonly called a 'fart sucker'!

@fntime Hitlers ideology was very similar to religion. He claimed to be the chosen one. chosen by god for his people. He claimed to lead the master race, but that was not founded in biology, it was founded in belief. He didnt do any actual science. Not science and reason was the problem but faith. So your hitler=atheism comparison fails. And your personal insults fail right off the bat cause you dont know me.

[fntime]

Children understand what they are told, just like you, remember how Hitler told the Germans they were a master race, even the children, Hitler Youth, agreed. You need to go back to the drawing board, your idealogy is incomplete, like your intelligence. You are indoctrinated in a foolish belief system, just like the Nazi's. In many ways, you are as closed minded as the creationist, you start with a conclusion, then add your premises. Being dumb that is favor, is still dumb.

[omnissient]

because even children can understand evolution. just creationists cant.
