    Doubts....

    Simplest way I could think of is that: i is always moving across in a horizontal direction, in a positive manner. j is moving vertically in a positive manner. Usually this is specified though. When you think about magnitude, simply use Pythagoras to find the hypotenuse, which is the...

    Doubts....

    Uhh, it's all I've seen come up, and it's the only ones I've seen mentioned in questions since 2005, so I hope so :P They rarely ask for definitions anyway, you just assume things are simple :)

    Doubts....

    Meaning of light, inextensible, what to do when an object is modelled as a particle, meaning of uniform and non-uniform etc.

    I started from 2005, and did all the winter and summer ones too. And I have to admit, I couldn't agree more, it's all about practise, you get used to what they want you to do, and the styles are always very similar. If you get in enough practice everything is good. It doesn't really matter when...

    Biology Hellp Urgently needed !!!

    Okay basically. The primary structure is the sequence and length of the amino acid chain. Different proteins have different R groups, which determines the type of bonds they can form, and thus the shape of the active site. As enzymes are specific, the active site needs to be certain shape for it...

    Bio unit 1, doubts, notes and discussion :D

    Thats semi conservative replication :P Which is when DNA helicase unzips the DNA, and the two strands are seperated. Then, free nucleotides which are complementary join up, forming hydrogen bonds, and creating a double helix due to DNA polymerase and ligase creating bonds.

    Bio unit 1, doubts, notes and discussion :D

    mRNA is created from the antisense strand of the DNA, and is complementary to it. The DNA itself is unzipped, and nucleic acids line up against the DNA with hydrogen bonds forming between complementary bases. This part is called Transcription. Then, the mRNA moves out of the Nucleus and enters...

    Bio unit 1, doubts, notes and discussion :D

    DNA replication, do you mean the steps which are involved in protein synthesis, or semi conservative replication?
