VIRUS !!!!!!

• WHAT IS ACTUALLY VIRUS MEANING FOR ?

• HOW THE CHARACTERISTIC ?

What is that???

Virus → POISON Was founded

virus for the first time on 1883

He was researching the spots In

TOBACCO PLANT

According to his

observation

that parasit can not saw even with the usual microscope. But use the electron microscope .

So the PARASIT is

SMALLER than

BACTERY ???

WOW

UNBELIEVABLE!

!!

He gave name “filterable Virus as it name” for the

first time (virus lolos saring).

So what about Wendell Stanley’s discovery that VIRUS can be crystallization ?

if that it so, why it can be reproduction ?

LET’S CHECK IT OUT

Body Structure Of VirusVirus classified as animate

objects (makhluk hidup) for some reasons :

The body formed by nucleic acid (asam nukleat)

Can be reproduction

Virus classified as inanimate objects(benda mati) for some reasons :

1 •It is not a cell because it doesn’t has cell wall, membrane, cytoplasm, core(inti), cell organelles.

2 •Could be crystallization

3 •Only live and fertilization in other cell organism

This is a bacteriofag virus like T (fag T4). It has a parts of the body, such as the head , collar(neck)/leher, and tail. On part of the tail has base plate (lempengan dasar),pin(jarum penusuk), and tail fiber(serabut ekor).

breed(berkembang biak) with the replication way

(multiply)/memperbanyak diri into the host cell.

Energy and the material for the process of protein

synthesis all over from the host cell.

Reproduction of the virus consists of five stages

Virus

Reproduction of Virus

THE FIVE STAGE :

•Adsorpsi stage

• Penetration stage

Maturation stage

(Pematangan)

•Synthesis stage

Lisis stage

2) The part of tail

sheath(selubung ekor)

make a hole that can break

through the wall and

membrane cell. 3) DNA from the

host cell has controlled by the genetic matery of

virus for make nucleic acid and protein of virus

component.

4) Results from synthesis stage of nucleic acids and protein are assembled into complete virus particles until forming new

virions(partikel lengkap virus).

5) The new viruses are get outside from it and will attack another host cell anymore. The host cell has broken

1) When the virion

(complete particle virus)

stick to the cell.

On the lysis stage there are two possibilities of cycle(siklus). Litik cycle and

lisogenik cycle.

The function of virus in this life

Virus actually live with parasit, however there is some virus who is useful in this human life. Such as:Virus of medical treatment to kill bactery, mushroom, or protozoa who are have characteristic pathogen (menimbulkan penyakit). To fight pest(hama). Cause some virus live with parasit in insect of pest(serangga hama).

Some of virus who are damage us.

Such as:

• The symptom(gejala) of it such, cough(batuk), fever(demam), sneeze(bersin), eye becomes red, canrise(menimbulkan) some brown spots(bercak) on your skin.

MEASLES

caused

by Morbillivirus

AIDS

can contaminate covered by

sexual interaction

DENGUE FEVER

Marked with symptoms of shivering and

headache. It is caused by DENGUE VIRUS

(Flavivirus) through the bitten of AEDES

AEGYPTI mosquito.

EBOLA

This virus attack your white blood cells and then

spread(menyebar) into your all body until caused a blooding

even the death.

influenza

Caused by parainfluenza virus

BIRD FLUCaused by HPAIV (highly pathogenic avian influenza virus). Can contaminate by the fowl.

That’s all our simple matery about VIRUS! Just WATCH OUT

for this organism.

CLOSING PART

Biology is one of our favorite lesson. You know why? Because we think without biology we can not to be here until today. Why do I say that? For example your mommy is pregnant, it’s gonna be terrible if there is no a doctor, Oou MY god she will death instantly , so you have to say thank to the doctor, and doctor is very very proud for what he has. THAT’S RIGHT his ability of BIOLOGY.

Biology is liven in your life, and you can’t run away from it. You could learn match, physic, chemistry, or whatever that, but you couldn’t stay away from biology. From elementary school you should have to learnt it. Off course it is, that is important thing. Biology is lead us to know about who you are? What was do we come from? How that it so? . So, LOOK AROUND YOU GUYS! can you see the happy animals, the beautiful creatures as a creation of god? Exactly biology is give us a learn to thank god for EVERYTHING We have. THAT’S ALL THE POINT FROM BIOLOGY!

You MUST to Answer the

simple questions from us. okey??

EXERCISE!• When virus was founded for the first time ?

And who was found it ?

• Would you like to mentioned the five stage of virus’s reproduction ?

• Did you remember that virus?what disease is caused by the virus ?
