RNA VIRUS

this is bit complicated but once u get it it's very useful....
PCR causes amplification so will fill FAT BORA SO

2(PCR)=2FAT BORA

PARAMYXO H
PICORNA I

CORONA C
CALICIVI I

RETRO C
RHABDO H

FLAVI C
FILO H

ASTRO I
TOGA I

BUNYA H
ORTHOMYXO H
REO I
ARENA C

to remember there symmetry use a bit of immagination...
first letter of all 3 is HELICAL i.e paramyxo,flavi,bunya

picorna has i so ICOSAHEDRAL
calcivi and corona both starts with c but
calicivi has i so ICOSAHEDRAL
corona is COMPLEX

retrovirus we know r diff from others so COMPLEX
rhabdo has h so HELICAL

filo been d first in fat is HELICAL
flavi is compared to flavour which is a complex sensation so COMLPEX

astro & toga both r ICOSAHEDRAL

bunya is HELICAL
orthomyxo same as paramyxo so HELICAL

reo is ICOSAHEDRAL
arena..thinking of arena as karena kapoor is a complex thought so COMPLEX

ALL HELICAL AND COMPLEX R ENVELOPED
ONLY ICOSAHEDRAL WHICH IS ENVELOPED IS togaviridae..
