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


Who's the moron who wrote about protein synthesis :sleep:

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...:D:D:D
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

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

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.

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

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?

nope. its used as a 'blueprint', cause DNA is the blueprint of life (haha, get it?! sorry, that was bad...:p) 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...
