Viruses &
Immune System
- Cycles of Phages
- Lytic Cycle
- phages infect a healthy cell, phage DNA is
injected as host DNA degrades,viral genomes
and proteins synthesize, then 3 sets of
proteins self-assemble to form heads, tails,
and tail fibers. The cell then lyses and
releases the bacteria. This kills the cell.

- Lysogenic cycle
- phages infect a healthy cell, phage DNA is
injected, phage DNA circularizes, phage DNA
integrates into bacterial chromosome
(prophage), bacterium reproduces and copies
the prophage to its daughter cells, daughter
cell obtains prophage. The cell is not killed.

- temperate phage
- also known as lambda phage,
these phages can replicate in
both cycles

- Lytic Cycle
- medication used against viruses
- antibiotics
- do not work against viruses
since they are nonliving, and
antibiotics work only against
living things
- FDA
- also known as the Food and Drug
Administration, they check medicines and
products to make sure they are safe for
consumption.

- treating viral infections
- infections can be treated by getting vaccinated.

- Types of Cells
- retrovirus
- an RNA animal virus where the
enzyme reverse transcriptase,
which transcribes RNA into DNA

- B cells
- lymphocytes that remain and
mature in the bone marrow
- lymphocytes that remain and
mature in the bone marrow
- T cells
- lymphocytes that migrate to the
thymus and mature there

thymus and mature there

- Defenses against viruses
- nonspecific defense
- they include skin, mucous
membranes, and secretions
- they include skin, mucous
membranes, and secretions
- innate immunity
- molecular recognition relies on a small
set of receptor proteins that bind to
molecules or structures that are
common to a group of viruses, bacteria,
or other microbes. Present at birth with
broad defenses

- acquired immunity
- molecular recognition
relies on a vast arsenal of
receptors which recognize a
feature typically found in a
pathogen

- defense against
foreign pathogens
- defenses include skin, mucous
membranes, secretions,
antibodies, inflammatory
response, antimicrobial
proteins, natural killer cells, and
phagocytic cells

membranes, secretions,

response, antimicrobial
proteins, natural killer cells, and

- autoimmune disorder
- a disease where the immune system is active
against particular molecules in the body

- fevers
- response by the immune
system in an attempt to
destroy pathogens by raising
the body temperature
