    Well, now that I know I am a dummy, I can (hopefully) ask any questions I want without being criticized about not already knowing it :P. Well here they are:

    1.Can a specific gene or allele be modified? If so how?
    2. If I'm right then the reasons cells are different and do different things is because the cells are set up differently. If I'm right please explain more, but if I'm wrong explain fully.
    3.How does a virus work?

    There they are, If you can answer them I would be grateful.

    Thank You,
    Benito

    1. Genes can indeed be modified using modern technology. Genome manipulation is a very big field and I have neither the time nor the knowledge to explain every aspect of it. You would probably be best off finding a book on genetics for a question so broad.

    2. I'm not 100% sure what you're saying here. There are many things which result from different combinations of genes. Everything from albinism to Huntington's.

    3. Viruses, in simplest terms, invade a cell with their genetic information and reprogram the cell to replicate the virus. Usually, this kills the cell. Virology is actually incredibly interesting and you could again learn a lot from a book that simply can't be explained in the confines of a forum.

    Is there a reason you're asking these questions? Knowing what your goal for this information is might help the answers be a little less generic. Are you interested in a certain aspect of genetics?

    Wow, thank you for all of your help, Well in number 2, i read in genetics for dummies, that the reason cells could do different things and have different purposes were because the organelles were set up differently depending on the DNA, thats what i got out of it at least. There is no specific reason I was asking these questions, i was just interested in it and the only book I have about cells and genetics is genetics for dummies (I just started getting into genetics). So if you could tell me some good books that cover virology and gene manipulation, that would be appreciated.

    Thank You,
    Benito

    the cell, and principles of gene manipulation. both my books from school.

    bol.com | Molecular Biology Of The Cell, Bruce Alberts & Alexander Johnson | Engelse...
    bol.com | Principles of Gene Manipulation and Genomics, Sandy B Primrose & Richard...

    I think i can answer your second question.

    Cell specialisation, or differentiation doesn't mean it's genetic code has been altered. Apart from mutations, or reproductive cells, all your cells contain the same genetic code. Wether it's wrapped and wrapped again, and wrapped again, or if it's open for reading, determines the availability of a gene, and thus the purpose of the cell.

    Growing up, i marveled at star-trek's science, and ignored the perfect society. Now, i try to ignore their science, and marvel at the society.

    Imagine, being able to create matter out of thin air, and not coming up with using drones for boarding hostile ships. Or using drones to defend your own ship. Heck, using drones to block energy attacks, counterattack or for surveillance. Unless, of course, they are nano-machines in your blood, which is a billion times more complex..
