    1) what is DNA profiling(fingerprinting) used for?

    2) What is genetic code?

    3) what is meant by mutation?

    4) are all mutations harmful?

    5) list the processes that cause genetic variation in living organisms.

    6) why aren't variations caused by the environment, such as a cat losing its tail in an accident, passed on to the offspring?

    7) how did lamarck's theory of evolution differ from Darwin's theory of evolution?

    8) wha is artificial selection?

    PS: if someone can find me some information on lamarck's theory of evolution that would be great

    It is not early! trust me how many other subjects do you have??
    do not underestimate the amount of work to be done for biology unit 2
    Ok, give me one month when I hand all my coursework in.

    Agreed. Even though June 16 may seem a long time away. There's a lot of content to cover which is quite hard and difficult to understand. Remember for most of us this is the only opportunity we will have to take this exam in June, so we will have to be confident about what we learn and leave plenty of time so not to be cramming during the last few days/weeks.

    1) what is DNA profiling(fingerprinting) used for?
    Duno - where is this ?
    2) What is genetic code?
    a sequence of nucleotide bases on a gene

    3) what is meant by mutation?
    a change in the genetic material of a cell

    4) are all mutations harmful?
    no no. not always.

    5) list the processes that cause genetic variation in living organisms.
    crossing over, genetic reassortment and random mutation

    6) why aren't variations caused by the environment, such as a cat losing its tail in an accident, passed on to the offspring?
    because the cat will still have alleles for making tails?

    7) how did lamarck's theory of evolution differ from Darwin's theory of evolution?
    never heard of 'im

    8) wha is artificial selection?
    not a clue.

    Not sure why I bothered when I can't answer all of them lol

    Exactly, also don't forget rest of the subjects and this unit has 10 chapters unlike the previous one which was around about 6?>

    I know RNA interference is beyond our syllabus but it is interesting stuff
    in the future scientists will be able to switch off RNA/DNA of HIV which would save alot of lives
