Advantages of in vivo cloning: *Extremely rapid - *Doesn't require living cells - no complex culturing techniques that require time and effort are needed
Advantages of in vitro cloning: *Useful when introducing a gene to another organism - * Almost no risk of contamination - gene is cut by the same restriction enzyme matches the same sticky ends of the opened up vector *Very accurate *Cuts out specific genes - more precise *Produces transformed bacteria that can be used to produce large quantities of gene products - bacteria can produce proteins for commercial or medical use
Hope that helps, don't know exactly how much detail but I'd make notes on everything just to be on the safe side, they might ask questions where you just need brief examples but then there's always a risk of a huge question asking for lots of detail.
Lol u got them the wrong way round bro. In Vitro is the gene cloning, which is done out of living organisms so THAT IS PCR. In vivo is the gene cloning done within living organisms when you introduce a gene vector into a bacterium to be cloned.
Oh here we go neg me just because I pointed a fault on your precious knowledge
I am retake student so I did them all last year. I tried doing them again but I wasn't coming up with answers so much as I was remembering them from when I had previously done them :/
I know this was a long time ago but does anyone think that the EMPA grade boundaires will be high/low?
I think they will be a tiny bit higher this year as photosynthesis isn't exactly a hard topic. PLUS loads of people have been cheating and giving answers away on EMPAS so yeah...I predict them to be high this time

Oops, thanks for pointing that out. Btw I didn't neg you, I've literally just seen your post so it was someone else
Why put pondweed in an aquarium? - So the fish have a place to hide from predators like a shark - to provide a habitat for symbiotic bacteria which can benefit the fish by eating dirt off their scales to keep them clean (I think I meant zooplankton, not that either would be in the MS)

I'm not completely stupid I just panicked a lot.
haha i'm sure you made up for it in the other marks... i think for that one i put so that its more like the fish's habitat, so it doesn't get stressed.. lol
I know i'm on the wrong unit but does anyone know where I can get the unit 4 paper and mark scheme from January? The Unit 4 thread is really dead If anyone knows it would be greatly appreciated, sorry again for interrupting
hows everyone revising/ preparing for the 25 mark essay?!! please guys im really struggling
I'm writing out extremely detailed essays for literally every topic i can think of that they could ask about (written 14 so far), and I'm using the internet and books to find off spec relevant info as I go. I'm writing more than I would have time for in exams, but it's just something to revise from.
I'm then reading them repeatedly, writing out plans for each and trying to learn them. This way not only am I prepared for the essay, but as the essays cover the entire spec in detail, it's great revision for the whole paper
yeah ive got this book! how are you using it and how are you revising for the essay? are you just writing loads of them? im really worried i havent done anything for the essay so far
