Prokaryotes and Eukaryotes Flashcards
1
Q
DNA in eukaryotes
A
- linear strands of DNA (Chromatin)
- different organisms have different numbers
2
Q
Ribosomes in eukaryotes
A
- larger than in prokaryotes
- not sensitive to antibiotics
3
Q
prokaryotic flagellum
A
- considered extracellular (no surrounding membrane)/
- rotating shaft design
- composed of flagellin protein
4
Q
cell division of prokaryotes vs eukaryotes
A
euk: mitosis or meiosis
pro: binary fission
5
Q
DNA in prokaryotes
A
- single circular chromosomes (nucleoid)
- in archaea histone proteins are attached to DNA while it is not in bacteria
6
Q
eukaryotic flagellum
A
- intracellular (has a membrane surrounding it)
- two microtubules with dynein in between that causes bending
7
Q
ribosomes in prokaryotes
A
- smaller
bacteria - sensitive to drugs
archaea - not sensitive
