it's been quite awhile since i last posted well nothing much to post anyway until last friday well shall post 2 things today...
firstly,this is something i learned that's all around waiting to seize our cells....virus!
(shall use this to help a little on my revision so pardon me if it get's too chim and bio :P)
Viruses are obligate intracelluar parasites...meaning? they Bind(obligate) to a host cell and within the host cell(intracellular),they caused diseases ( parasites ) why? because they lack metabolic enzymes and organelles for protein synthesis need the host's polymerases and ribosomes in order to replicate and synthesise virions even though they're similar to human or any other living organisms with genetic material ,either Dna or Rna,single or double stranded,protected by capsid made of capsomeres.overall they are known as nucleocapsid (:
they can be helical,icosahedral,or complex in shape. An example of complex shape is BACTERIOPHAGE...here:

next might not be as boring...animal virus= influenze virus commonly known as flu (:
that's why we have H1N1 swine flu or H5n1 avian flu.these are Type A viruses that are infectious,causing human pandemic.
Type B and C however are small and mild without subtype so dun bother (:
It has an envelope with glycoproteins(glycogen + proteins):
Hemagluttinin(HA) for binding to target cells and
Neuraminidase(NA) for release of progeny virus (offspring of viruses) from infected host cells.
These 2 are antigens where antibodies in body or antivial drugs(medicine) can be found.they look like this :

nice eh??? haha
alright enough of biology,now's about yesterday...nothing exciting,morning had tuition,then went out with bro for movie at suntec,harry potter and the half-blood prince (:


well overall it's not that bad but the previous series are better and i seriously think harry and hermione should be together lol! XD

the ending is a little sad though and i hope the next movie comes fast...because the story have yet to end...leave it hanging there....make the audience disappointed...lol those who have watched it will understand why (:
oh well that's all for now....bye~
