1. Structure and The structure of viruses includes a core of genetic material, either DNA or RNA,
Classification of surrounded by a protein coat called a capsid. Some viruses also have an outer lipid
Viruses envelope. Viruses are classified by their shape, type of genetic material, presence
of an envelope, and how they replicate.
2. Capsid A capsid is the protein shell that surrounds and protects the genetic material of a
virus.
3. Viral Genome A viral genome is the complete genetic material (either DNA or RNA) carried by a
virus, containing all information necessary for replication.
4. Virion A virion is a complete virus particle that can exist outside a host cell and can infect
new cells.
5. Assembly Assembly is the stage where newly made viral proteins and genomes are put
together to form new viral particles inside the host cell.
6. Attachment Attachment is the first step of the viral replication cycle, where a virus recognizes
and binds to specific receptors on the surface of a susceptible host cell.
7. Host Cell A host cell is a living cell which a virus infects and utilizes for replication of its
genetic material and construction of new virus particles.
8. Lysogenic Cycle The lysogenic cycle is a viral replication method in which the viral DNA becomes
integrated into the host cell’s genome and can be replicated together with it,
without immediately destroying the host cell.
9. Lytic Cycle The lytic cycle is a type of viral replication where the virus quickly replicates within
a host cell, leading to the complete destruction of that cell and release of new
viruses.
10. Release Release is the final step in the viral life cycle in which newly assembled viruses exit
the host cell to spread to new cells.

11. Replication Replication is the process where the virus uses the host cell's machinery to make
copies of its own genetic material.
12. Uncoating Uncoating refers to the stage in the viral cycle when the viral capsid is removed,
releasing the viral genome into the host cell.
13. Viral Composi- Viral composition refers to the basic structure of viruses, which typically includes
tion and Function genetic material (either DNA or RNA), a protein coat called a capsid, and, in some
cases, a lipid envelope. Viral function describes how viruses use their structure to
infect host cells, replicate their genetic material, and produce new virus particles.
14. Immune Re- Immune responses to viruses are the ways the body's immune system detects
sponses to Virus- and fights viral infections. This includes both innate defenses, like interferons, and
es adaptive responses, such as antibodies and T cells targeting the virus.
15. B-cell Responses B cells are immune cells that produce antibodies when exposed to virus particles.
and Neutralizing Some antibodies, known as neutralizing antibodies, can block the virus from
Antibodies infecting cells. B-cell responses are a vital mechanism for marking viruses for
elimination and creating lasting immunity.
16. Affinity Matura- Affinity maturation is the process by which B cells produce antibodies with in-
tion creased strength and precision for binding to a specific viral antigen.
17. Antigen-Specifici- Antigen-specificity is the ability of a B cell or antibody to recognize and bind to
ty very particular molecular structures, called antigens, found on viruses.
18. Epitope Recogni- Epitope recognition is the ability of B cells and antibodies to identify and bind to
tion specific regions, called epitopes, on the surface of a virus.
19. IgG IgG is a common type of antibody found in blood and tissues. It is important for
providing long-lasting protection against viral infections.
20. Neutralizing Anti- Neutralizing antibodies are proteins made by B cells that can bind to a virus and
bodies block its ability to infect cells.

21. Virus Neutraliza- Virus neutralization is the process by which antibodies prevent a virus from
tion infecting cells, often by blocking its ability to attach or enter the host cell.
22. Innate Immune Innate immune detection of viruses refers to the body's first line of defense that
Detection of recognizes and responds to viral infections quickly and non-specifically. Special-
Viruses ized cells and receptors detect viral components, triggering immediate immune
reactions to limit virus spread.
23. Innate Immune Innate Immune Activation refers to the initial response of the body's immune sys-
Activation tem when cells detect viruses, launching broad protective actions before specific
immunity develops.
24. Pattern Recog- Pattern Recognition Receptors are proteins on or in cells that recognize common
nition Receptors molecular patterns found in viruses and other pathogens, helping the immune
(PRRs) system detect infections quickly.
25. RNA Sensors RNA Sensors are receptors inside cells that recognize viral RNA and trigger im-
mune signaling to fight infection.
26. Type I Interfer- Type I Interferons, which include IFN-α and IFN-β, are signaling proteins pro-
ons (IFN-α/β) duced by infected cells that help control viral infections and alert nearby cells to
the presence of the virus.
27. Viral PAMPs Viral PAMPs (Pathogen-Associated Molecular Patterns) are distinctive molecular
patterns found in viruses that can be detected by host immune sensors to activate
immunity.
28. DsRNA Recogni- dsRNA Recognition is a process in which cells sense double-stranded RNA (com-
tion mon in viral infection), which prompts immune defenses against the virus.
29. Role of Interfer- Interferons are signaling proteins released by virus-infected cells. They help
ons in Antiviral prevent the spread of viruses by triggering antiviral defenses in nearby cells,
