Lecture 24C Flashcards
genera are
groups
bipedalism results in
many coordinated changes in anatomy
homo sapiens appears first in
northeastern africa 195000 year ago
homo neanderthals
europe middle east
homo erectus
asia
homo sapiens evolved how many years ago?
200,000 years ago
is most human variation polygenic or discrete
polygenic
is skin color discrete or complex
complex(polygenic)
Active TB
Contagious bacterial infection that primarily affects the lungs
anopheles mosquitos
Mosquito that can transmit the parasite responsible from malaria
antibiotic resistance
when bacteria evolve to withstand the affects of antibiotics, making medication’s less effective in treating infections
conjungation
process in bacteria, where genetic material is transferred between two cells, enhancing their abilities and characteristics
directional natural selection
where a trait becomes more common in a population, because it provides a selective advantage
horizontal gene transfer
Exchange of genetic material between different organisms (often bacteria)
Latent TB
where a person is infected with TB bacteria, but does not show symptoms of(bacteria is inactive)
Malaria
caused by plasmodium parasite transmitted to through mosquito bites
mycobacterium TB
Bacterial responsible for causing tuberculosis in humans
plasmid
small circular piece of DNA found in bacteria, carry extra genes that provide advantages such as antibiotic resistance
plasmodium
Genus of parasitic protozoa that causes malaria in humans
protist
diverse group of microscopic organisms that don’t fit into the other categories. Including some that can cause diseases
rifampin
Antibiotic used to treat bacterial infections, including tuberculosis
Rna polymerase
Enzyme that helps make RNA by reading instructions from DNA
transcription
Process where genetic information in DNA is used to create a messenger molecule called RNA
Transduction
method of horizontal gene transfer viruses help carry genes from one bacterium to another
Transformation
Process in which bacteria picks up new pieces of genetic material from the environment
tuberculosis
bacterial infection that often affects the lungs
