Viruses are infectious agents with genetic material, while prions are misfolded proteins causing neurodegenerative diseases.

virus the genetic Invader a virus is a
0:03
microscopic pathogen composed of genetic
0:06
material DNA or RNA enclosed in a
0:09
protein coat sometimes with a lipid
0:11
envelope it invades living cells to
0:14
replicate hijacking the host's Machinery
0:16
viruses cause diseases like influenza
0:19
HIV and
0:21
covid-19 pron the misfolded protein a
0:25
pron is a misfolded protein that can
0:27
induce normal proteins in the brain to
0:29
misfold leading to neurodegenerative
0:31
diseases pran lack genetic material and
0:34
reproduce by altering the structure of
0:36
other proteins they cause conditions
0:39
like kitsfelt yakub disease and mad cow
0:42
disease structure complex versus simple
0:46
viruses are complex entities with
0:48
genetic material and a protective
0:50
protein shell in contrast prion are
0:53
extremely simple consisting only of
0:55
misfolded proteins with no DNA or RNA
0:59
mode of infection
1:00
cell Invasion versus protein conversion
1:03
viruses infect and replicate within host
1:05
cells using them to produce more viruses
1:09
pans however spread by converting normal
1:11
proteins into their abnormal form
1:13
disrupting brain function diseases
1:16
caused widespread versus
1:19
neurodegenerative viruses cause a wide
1:21
range of diseases affecting various
1:23
organs and systems from the common cold
1:25
to hepatitis PR exclusively affect the
1:28
brain and nervous system system leading
1:30
to fatal neurodegenerative conditions
1:33
reproduction genetic replication versus
1:36
structural transformation viruses
1:38
replicate by injecting their genetic
1:40
material into host cells pans propagate
1:44
by inducing structural changes in normal
1:46
proteins with no genetic material
1:48
involved in the process transmission
1:51
diverse versus limited viruses spread
1:54
through multiple Roots including air
1:56
bodily fluids and contaminated surfaces
2:00
pryan are transmitted primarily through
2:02
infected tissue or ingestion of pron
2:04
contaminated food as seen in mad cow
2:07
disease detectability easier versus
2:10
challenging viruses can often be
2:12
detected using molecular techniques like
2:15
PCR or antigen tests prion being
2:18
protein-based are harder to detect and
2:21
require specialized methods like brain
2:23
biopsies or Advanced Imaging treatment
2:26
antivirals versus no cure some viral
2:29
infections can be treated with antiviral
2:31
drugs or prevented through vaccines pron
2:35
diseases however have no cure or
2:37
effective treatment making them
2:38
universally fatal conclusion distinct
2:42
pathogens with unique mechanisms viruses
2:45
and PR differ fundamentally in structure
2:47
replication and impact viruses rely on
2:51
genetic material to spread and cause
2:53
diverse diseases while pryes operate
2:55
solely as misfolded proteins leading to
2:58
devastating neurodegenerative condition
