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
![Page 4: Presentation virus](https://reader034.vdocuments.us/reader034/viewer/2022051404/589fff421a28abd40b8b49ed/html5/thumbnails/4.jpg)
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
![Page 7: Presentation virus](https://reader034.vdocuments.us/reader034/viewer/2022051404/589fff421a28abd40b8b49ed/html5/thumbnails/7.jpg)
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).
![Page 9: Presentation virus](https://reader034.vdocuments.us/reader034/viewer/2022051404/589fff421a28abd40b8b49ed/html5/thumbnails/9.jpg)
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
![Page 11: Presentation virus](https://reader034.vdocuments.us/reader034/viewer/2022051404/589fff421a28abd40b8b49ed/html5/thumbnails/11.jpg)
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.
![Page 24: Presentation virus](https://reader034.vdocuments.us/reader034/viewer/2022051404/589fff421a28abd40b8b49ed/html5/thumbnails/24.jpg)
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??
