Mb Flashcards
Molecular biology
The science of/ dealing with DNA and protein synthesis
Genome
Total DNA contain in a cell
Genome consists of
Chromosomes and any plasmid
Chromosomes contain?
Gene is?
DNA is?
- chromosomes contain genes
-Gene is a section of DNA that code for functional product
-DNA is a macromolecule made of nucleotides
How do mutations occur
Explain
Pathology
Study of disease
Etiology
Cause of disease
Pathogenesis
How disease is developed
Pathogen
Organism that causes disease
Pathogenicity
Ability to cause disease
Virulence
Ability to cause harm (severity of diseases
Infection
Growth of pathogens in the body
Disease
Abnormal state where the body is not capable of performing normal function
Symptoms
What a patient feels
Signs
An objective change a physician can measure
Syndrome
A specific group of symptoms and signs that is accompanied by a particular disease
A disease that spread from one host to the other is called
A communicable disease
Incubation
Time between infection and first signs and symptoms
Prodromal period
Early mild symptoms
Period of illness
Most severe signs and symptoms
Period of decline
Signs and symptoms subsided
Patient is still vulnerable to secondary infection
Can last hours and days
Period of convalescence
Recovery occurs
The pathogen can still be spread from patients to others
Can carry pathogen for years and months
Duration of symptoms
Acute
Chronic
Latent
Acute
Rapidly developing and slow duration e.g influenza
Incubation period - period of illness- convalescence
Acute illness is short term cause pathogen is eliminated by the host defenses; person is usually immune to reinfection
Chronic
Chronic is slow to develop and continual duration e.g tuberculosis
Incubation—illness (long lasting)
Chronic; illness persists over a long period of time
Latent
Inactive for a period of time and can be reactivated e.g cold sore herpes
Incubation- illness period-convalescence-latency- recurrence
Latent;illness may reoccur if immunity weakens
