VIRUSES, VIROIDS AND BACTERIPHAGES

VIRUSES:

TERM VIRUS( INFECTIVE FLUID) WAS COINED BY PASTEURE
D J IWANOWSKY DISCOVERED VIRUS ( TMV)
MW BEIJERINK CALLED VIRUSES TO BE INFECTIVE - EXTRACT FRO INFECTED TOBACCO COULD CAUSE INFECTION TO HEALTHY PLANTS. ( CONTAGIUM VIVUM FLUIDUM)
W.M STANLEY : CRYSTALLISED VIRUSES

VIRUSES ARE THE CONNECTING LINK BETWEEN LIVING AND NONLIVING

STRUCTURAL COMPONENT;

ENVELOPE ( HIV, HERPES)
CAPSID
NUCLEOID ( DNA OR RNA)

DNA CONTAING VIRUSES:

DS DNA- POX VIRUS, HERPES VIRUS , CMV
SS DNA VIRUSES- COLIPHAGE $\phi$ X174, M-13 PHAGE

RNA CONTAING VIRUSES

DS RNA- REOVIRUSES, WOUND TUMOUR VIRUSES
SS RNA VIRUSES -HIV, TMV, RETROVIRUSES

BACTERIOPHAGE

DOUBLE STRANDED DNA
TADPOLE LIKE STRUCTURE- POLYHEDRAL HEAD AND A HELICAL TAIL
HEAD- NUCLEIC ACID + PROTEIN COAT
TAIL - PROTEINACEOUS

TMV

ELONGATED ROD LIKE
2130 CAPSOMERES ARRANGED HELICALLY
SS RNA( 6400 NUCLEOTIDES) AS GENETIC MATERIAL
RATIO OF NUCLEOTIDES TO CAPSOMERES 3;1

VIROIDS, VIRUSOIDS AND PRIONS

VIROIDS: DISCOVERED BY AO DIENER, INFECTIVE RNA PARTICLES DEVOID OF CAPSID ( PROTEIN COAT),CAUSE DISEASE LIKE PSTD( POTATO SPINDLE TUBER DISEASE)
VIRUSOIDS: INFECTIVE RNA PARTICLES PRESENT INSIDE THE CAPSID OF OTHER LARGE VIRUSES
PRIONS: INFECTIOUS PROTEIN PARTICLES

Open Ended
