UR FUCKING PISSING ME OFF U DUMB HITCH IM NOT A LEBSIAN BRO ILL FUCKING DOX YOU

BRO COOLCAT IS A GUY DONT TELL ME UR THAT FUCKING RETARDEDFRE

 

[reniiiblaseee]

BRO COOLCAT IS A GUY DONT TELL ME UR THAT FUCKING RETARDEDFRE

UR A FUCKING GUY WHAT R U ON

 

[lolcti]

UR A FUCKING GUY WHAT R U ON

I WISH I WOULD BE SUCH A DOMINANT ARAB FINE SHYT

 

[reniiiblaseee]

I WISH I WOULD BE SUCH A DOMINANT ARAB FINE SHYT

SHUT UP AYRI UR FUCKING IDIAN

 

[lolcti]

SHUT UP AYRI UR FUCKING IDIAN

SHUT UP U GAHBA IM LITERALLY GOING TO DOMINATE U IN BIO

 

[reniiiblaseee]

SHUT UP U GAHBA IM LITERALLY GOING TO DOMINATE U IN BIO

CUZZZZ IM FKN SCREENSHOTTING THIS SO U CANR DENY BEIBG ARAB

guys fight coolcat not each other what

My fucking answer:
Ultra Violet radiation
Ultra fucking violet radiation can fucking destroy the bonds between atgc, causing an infection, thus creating a germline mutation.

Do you want to know what the fucking irony is? My response, even though I don't do this crap subject for obvious reasons, is much deeper than the stupid sample answer. Like no fucking shit it destroys DNA, can you tell us how?

Bro what has bio done to you D:
Btw I don't think skin cancer/uv radiation will damage your eggs/sperm cells, UV radiation forms Thymine dimers which disrupts the double helix structure. When structure broken it can't replicate and thus it mutates

I think it can have the same effect on germline cells as somatic cells, causing mutations in gametes, but you're right about how it doesn't disrupt the A-T G-C bonds. It only really forms pyrimidine (C/G) dimers, which distort DNA structure and lead to insertions/deletions during DNA replication. Remember that germline cells (not gametes) can also undergo mitosis to proliferate, and that DNA replication occurs before meiosis too

Do we need to know the actual process of the Polymerase Chain Reaction (PCR) or just its uses?

I remember we were taught the process but idk if it’s been tested before

It's not too hard to remember the process, so I'd learn it just in case
1. denaturation: heated to separate the double strand
2. annealing: primers bind
3. extension: Taq polymerase extends the primers to synthesise new strands
4. repeat through several cycles in the thermal cycler

I think that's all the depth you need to know it to

 

[Study to success]

so glad I'm dropping this subject

No definitely know the process its part of the syllabus and can be asked. It's used in sequencing, profiling and SNP analysis so if they ask those processes you'll need to explain PCR as well. I feel like thy might ask it this yr.
It's basically dna replication but artificial so it shouldn't be too hard to learn.

question: for pasteur's flask neck experiment conducted in a school lab setting, what's the control group? Cause one flask would have an S-neck while one won't, but won't they both be independent variables? thanks

I think the straight-necked flask is the control. It isn't really an independent variable because it doesn't change anything - it just shows what would happen under normal conditions, i.e. the microbes can freely enter through the air. Correct me if I'm wrong

bro nesas gonna fuck us over with bio since the last two years have been piss easy

I think the flask which is open and has been heated, as this disproved the notion of sponatneous generation, meaning that the microbes must have been introduced from the surrounding external environment, compared to the swan necked flask which has no microbes as it has been physically isolated from its external environment. So I would say the 'control' would be the open flask (the control also being the fact that the flasks were heated which would have killed any microbes previously within the broth.

Hopefully alignment can come in clutch this year in that case.

I think the independent variable is just observing microbial growth as evident by the changing colour of the open flask.
