where is DNA organized in bacteria
the nucleoid
where is the nucleoid region in prokaryotic cells
throughout the cytoplasm
eukaryotic vs prokaryotic cells and where DNA is stored
Eukaryotes: a well-defined nucleus with a nuclear membrane
Prokaryotes: a nucleoid region throughout the cytoplasm
how is the DNA structured in each domain?
it is supercoiled
what facilitates packing of DNA
DNA-binding proteins (e.g. HU)
how many loops/domains does the nucleus form
about 50
what is transcription?
RNA polymerase transcribes DNA into a single strand of RNA (mostly messenger RNA)
what is translation
mRNA immediately binds to a ribosome for translation into a polypeptide.
what aids mRNA in translation and how?
transfer RNA (tRNA), which brings the amino acids to the ribosome
how is translation and transcription different in prokaryotes than eukaryotes
they are tightly coupled
how is DNA of prokaryotes organized
into loops
