DNA polymerase

[qrais]

is one and the same DNA polymerase replicate both strands?

[skyblazer7]

How does the polymerase know it's creating the proper strand? How does it proofread without having an exact copy of the DNA inside it? Is it all atomic bonds or is there a 'ghost in the machine'?

@quikflow ur such a sad fucker

[jessemaurais]

Anyone think we'll ever be at the point of programming DNA for the design of cellular life, to the purpose of producing molecule factories?

[leaffan27]

see Craig Venter's research

@jessemaurais we have already done this - every day millions of diabetics receive a treatment of human insulin manufactured by bacterial factories. :)

what's the difference between thte 5' end and the 3' end? is it just phosphates are attached to the 5', and hydroxyl groups are attached to the 3' end?

[leaffan27]

yes there is a free phosphate group attached to 5' carbon at one end and a free hydroxyl group attached to the 3' carbon at the other..... plus nascent DNA is synthesized 5' --> 3'....also, the convention for writing out nucleotide sequences is 5' --> 3'

Holy science! I love polymerases!...It´s like a god, lol. I love Molecular Genetics

[tetranoob]

what word does she say at 0:56 ?

it sounds like ketalysis,

[leaffan27]

Catalysis....the function of the enzyme

thank you. quite helpful
