    oh =$ many thx to you ! =p
    have any prediction on the article ? =p
    Anytime.

    I'm very bad at predicting these stuff. Although I have a feeling totipotency may come. (Now I must have jinxed it and we get Mitosis). I heard that there's going to be something from risk factors - again not really sure about this. The article should be alright. Just read it carefully and know where they talk about the ethical, social, economical and environmental issues. They always ask something related to that. Other than that, just be confident. You'll do great.

    G1 - Synthesis of new DNA and histone proteins and synthesis of new cell organelles.
    S stage - Replication of the DNA that cause the DNA number to multiply.
    G2 Stage - Replication of the cell organelles synthesized in G1 and synthesis of other RNA and proteins.

    ^ Again don't need to know this. Just know the stages of Mitosis - Prophase, Metaphase, Anaphase and Telophase.

    I wrote about drugs and it's side effects and linked almost everything related to drugs from the article.
    Did any of you guys draw 2 piecharts about that question asking for visual representation? And what did you have to write on comment about validity?

    FYI thanks to the article, this paper officially was the worst of them all. Difficulty somewhere next to the paper which had garlic on bacteria.
