DNA replication (1 Viewer)

[~amy~]

can someone explain DNA replication. Im hoping i got a few marks for this.

Cutting and pasting using enzyme ligase through a cutting and grafting technique. Something like that


Who's the moron who wrote about protein synthesis

 

[acmilan]

Haha i was wondering when i saw it how much people would write about protein synthesis

 

[sgt]

somethn like...

• 
  dna is unwound by an enzyme
  dna is unzipped to form to separate strands
  1 nucleotide (base, sugar, phospate) is added to each strand
  each time 1 nucleotide is added, another dna strand is formed identical to the first

HAHAHA, who would write about protein synthesis? thats funny...
we had that same Q in the trial and heaps of ppl stuffed it up. DNA replication occurs before mitosis, when an ezyme unzips it (DNA polymerase), then free nucleotides attatch and form 2 new daughter strands. NO mRNA_tRNA_ribosomes involved

hardy ha...

 

[sgt]

hmm those bullets didn't work heh

 

[= Jennifer =]

alot of people in our class wrote on protein synthesis i found myself doing the same then i sort of skewed my answer away from it i think i might get 1 out 3 for that part

 

[~amy~]

i drew a picture with an explanation. i fluked this one cos i wasnt 100% sure i was doing the right process.

That's about what I wrote.

I'll probably get 2/3. I wasn't sure if I was doing the right thing and talked about mitosis and chromosones kind of.

thats for transgenic species isnt it?

 

[thejosiekiller]

i had a mental blank on this question for some reason

 

[hiphophorray123]

i knew everythin there except for the shit about dna replication and hybridisation

i wrote some bullshit like the m-RNA takes one strand to a station where it gets replicated, ie, a strand attaches to it with corresponding bases lol

 

[SweetSeasons]

What so some of you guys are saying, the question wasn't asking us to talk about mRNA and tRNA, but to talk about mitosis and how the chromatids split in half? or what ever it is?

HAHAHA, who would write about protein synthesis? thats funny...

hahah, i did. i shitted on about ribosomes and messenger rna for about six lines.

 

[silvermoon]

damn, i think i did too. cant remember - which is not a good sign - damn, is just the sort of stupid mistake i make in exams, dont read the question properly. damndamndamndamndamn. how much was it worth anyway? anyone remember? want to know how many marks i potentially lost (hopefully didnt tho! )

 

[katietheskatie]

three, i think. maybe they'll feel sorry for the vast number of people that wrote about protein synthesis instead ..

The DNA is still replicated... isn't it?

 

[callisto]

nope. its used as a 'blueprint', cause DNA is the blueprint of life (haha, get it?! sorry, that was bad...) DNA unravels, mRNA assembles w/corresponding nucleotides (A-U, G-C) then travels into cytoplasm, tRNA molecules match codons, ribosome does some other stuff and viola! you have a polypeptide chain of amino acids, NOT another double helix of DNA.

sorry people...

 

[Zarathustra]

All cells have DNA.. therefore I'm correct
*I misread the Q and am now clutching at straws...*
