Flashcards in 26.1 Two Prokaryotic Domains Deck (10)
what are the two domains characterized by prokaryotic cell structure?
bacteria and archaea?
in bacteria, a small circular molecule of DNA carrying a small number of genes that can replicate independently of the bacterial genomic DNA
plasmids may have genes that have adaptive value under...
specific environmental conditions
since no nuclear membrane separates DNA from the surrounding cytoplasm, transcribed mRNA is immediately....
translated into proteins by ribosomes
bacteria have both a plasma membrane and a...
because bacteria lack the membrane bound organelles in eukaryotic cells, metabolism is carried out by:
proteins that float freely in the cytoplasm or are embedded in the plasma membrane
the light reactions of photosynthetic bacteria take place in association with:
membranes distributed within the cytoplasm
a complex polymer of sugars and amino acids that makes up the cell wall of bacteria
how to photosynthetic bacteria gain CO2 and how do respiring bacteria take in small organic molecules and oxygen?
through diffusion from the environment into the cell
