Biology help

[Chinaski]

Much as I hate bothering other people with my academic problems, I'm in need of help for this particular biology assignment, so I can get it out of the way and focus on my essays on epistemology and English. I know that there are a couple of biology freaks on here, and any small indication of what I should be talking about (given as I don't know shit about this stuff) would be wonderful and make me love you forever.

1. Explain the use of 2 enzymes in biotechnology.

2. Outline the process of gene therapy using a named example.

3. Outline the differences between the behaviour of the chromosomes in mitosis and meiosis. In your answer, draw examples of dividing cells in metaphase I of meiosis and metaphase of mitosis.

4. Outline the processes of transcription and translation to form a polypeptide chain.

5. Explain oxidative phosphorylation in terms of chemiosmosis. Be sure to inculde the roles of NADH/ FADH2, electrons, oxygen, ATY synthase, and protons in your answer.

6. Explain the light-dependent reactions of photosynthesis, including cyclic and noncyclic photophosphorylation. Be sure to inlude the terms photosystem, photolysis, NADP+, NADPH, protons and ATP in your answer.

Thanks!

I could provide you with all of the answers with 20 minutes browsing wikipedia. But I believe that the idea is for you to actually learn this stuff, so I am going to let you browse wiki yourself, sorry.

Every question has a few juicy keywords you can use in wiki or google. The truth is out there.

Just tell teacher the dog ate it

Our answers would probably be about as useful as dog-sick anyway.

I will happily proofread your answers if you like, once you've done the bloody work!

[Chinaski]

Dammit, I just need some shortcuts so I can focus on the important topics >.<

Bah, spoilsports, the lot of you.

1) Pectinase is used to treat fruit juices and beverages , DNA ligase is used to fuse DNA together

2) Try X-linked Severe Combined Immunodeficiency Syndrome.

3) This might help http://image.tutorvista.com/content/cel ... arison.gif

5) NADH2 and FADH2 are high energy substrates produced during aerobic respiration (TCA + Glycolysis)
electrons are eventually used to form a water molecule at the Cyt C oxidase terminal electron acceptor, ATP synthase allows Hydrogen ions to get back into the matrix, using the Proton Motive Force that results to drive ATP synthesis.

Please tell me if you need more help, I'm a bit short on time now, and sleepy

[devogue]

Seriously. What is the point of that? How sad is that? How much study, work, nerdiness and boringness would be needed to come up with that.

Is it any wonder religion thrives?

[GenesForLife]

feck, isn't that the EMP pathway of Glycolysis?

[devogue]

[GenesForLife]

Devogue, that pathway is BEAUTIFUL, and it is a critical point in the metabolism of carbohydrates, responsible for the conversion of the glucose that is produced by the breakdown of other sugars into a chain of intermediates which are used to synthesize amino acids and lipids, and also generate ATP, which is the energy currency of the cell.

Disclaimer - The aforementioned opinion may be because I meet all the criteria you've mentioned to be able to appreciate this...

[Chinaski]

Shit man, thanks a lot! Biology is my weakest subject and I need to spend hours repeating the information just to make it stick.

Like that goddamm chart that Feck posted.
