Structure and function of viruses as they interact with organisms
Structural and molecular characteristics
Nucleid acid
DNA or ARN
Envelope
Lipid membrane from host cell
Capsid
Protein shell that protect genetic material
Proteins
Glycoproteins
Infection process
Penetration
Virus or genetic material enters the host cell
Replication
The virus uses cellular material to replicate
Attachment
Virus binds to specific receptors on host cells
Assembly
New virus particles are formed
Realase
Virus exit the cell
Importance of vaccines
Types of vaccines
Inactivated
Subunit
Attenuated
Vaccines train the immune system to recognize and fight the virus
History of virology
1930s
Electron microscopy allows visualization of viruses
1950s - 1980s
Polio and smallpox vaccines developed
19th century
Viruses identified as agents smaller than bacteria
21st century
mRNA vaccines, antiviral drug advancements
Role in evolutionary history
Evolutionary impact
Shaped immune system responses and species adaptation
Retroviruses
Integrated viral DNA in human genomes
