Bio/Biochem Flashcards
How is DNA organized in prokaryotes?
scattered in the cytoplasm instead of in a nuclear envelope like in eukaryotes
Explain the difference between gram positive and gram negative cells
gram positive cells have a thick layer of peptidoglycan and stain purple, gram negative cells have no or little peptidoglycan and stain pink
What is Binary fission?
A simple form of asexual reproduction that results in two identical daughter cells
What does it mean for bacteria to go under transformation?
The bacteria integrates foreign material into its genome
How does conjugation allow bacteria to reproduce?
It is a sexual form of bacterial reproduction, requires fertility factor (F-factor)
Transduction of bacteria requires?
A vector/virus to inject its DNA into the bacterial cell
What are the prokaryotic cell growth phases?
Lag phase, exponential phase, stationary phase, death phase
S phase of interphase involves
Doubling/replication of DNA before mitosis/meiosis
The sympathetic nervous system is responsible for
Fight or flight response
The parasympathetic nervous system is responsible for
rest and digest response
Which portion of the thalamus is responsible for vision
the lateral geniculate nucleus of the thalamus
Which portion of the thalamus is responsible for hearing
the medical geniculate of the thalamus
