Science and Technology Quiz 3

Anyways, I believe it's Sir Ramsey.

That's his name

 

[dido]

No and no. Letters to this scientist could theoretically go through the entire postal service with just five elements on the envelope

I thought you mean a post as in a job in university

oh well, gotta be some professor from UC Berkeley...somehow GN Lewis came to my mind

 

[Arakhor]

Sir Ramsey? What was his first name? (Incidentally, you don't refer to a knight by "Sir Surname"; it's always "Sir First Name" or "Sir First & Last Name".)

No, it's not that chap anyway. Dido is closer to the correct answer.

No, it's not that chap anyway. Dido is closer to the correct answer.

Still, what is the answer?

 

[Arakhor]

Glenn T. Seaborg, the only man to have an element publicly named after him whilst he was still alive.

The five elements are: seaborgium, lawrencium (named after the Lawrence Berkeley Laboratory in Berkeley, CA, where he worked), berkelium, californium and americium.

Who's up next?

 

[civ_king]

*yawn* what now?

 

[StarWorms]

What is the histone code hypothesis?

 

[SS-18 ICBM]

The origins of the genome is somehow related to histones?

 

[civ_king]

The origins of the genome is somehow related to histones?

I love the fact I actually read my biology book

I don't remember exactly but I think it is x-DNA "interactions" being directed by histone modifications

I don't remember what x is but it has something to do with chromosomes (I think)

I hate how we can't use the internet for help

 

[Arakhor]

Not much point if we did use the Net, CivKing

ish... I'm looking for a bit more detail, but it is to do with histone modifications.

 

[Perfection]

Histone modifications affect DNA

 

[civ_king]

Not much point if we did use the Net, CivKing

I just want to find what x is, I can't remember but I'm pretty sure I have everything else

 

[StarWorms]

Histone modifications affect DNA

In what way, and how do different modifications affect this?

 

[Perfection]

In what way,

biochemically

and how dodifferent modifications affect this?

depends on the modification

chromatin-DNA interactions are controlled by combos of histone modifications

 

[Brighteye]

My knowledge of histone coding is limited to histone methylation blocking transcription and acetylation enhancing it.

 

[civ_king]

those two that bright eye mentioned modify histone tails change the chromatin structure and BTW no one is entirely sure of how it exactly happens

This question has dragged on for nearly 72 hours now...
