VERIFIED RESPONSES GRADED A+
⩥ What is an unrooted phylogenetic tree?
Answer: shows relationships but not a common ancestor
⩥ Describe members of the Archaea domain.
Answer: Single called, microscopic organisms with prokaryotic cell
structure that reproduce by binary fission
⩥ What is a plasmid?
Answer: A single, circular DNA containing structures in the nucleiod
region.
⩥ What is distinct about the plasmids in the Archaea domain?
Answer: They include other organelles like ribosomes with unique
rRNA.
⩥ What is rRNA?
Answer: Ribosomal RNA, molecules that facilitate the assembly of
amino acids in a protein chain and form ribosomes within the cell.
,⩥ rRNA is a necessary component for all living things to...
Answer: Synthesize protein
⩥ rRNA is ____ and ____ to an organism
Answer: Unique, specific
⩥ What can rRNA provide insights into?
Answer: Evolutionary relationships between organisms with different
domains and kingdoms
⩥ What is a pseudopeptidoglycan?
Answer: Branched, hydrocarbon chains attached to a glycerol via ether
linkages
⩥ What are extremophiles?
Answer: A small subset of archaea that thrive in extreme environmenrs
⩥ What are helophiles?
Answer: Organisms that thrive in extreme saline conditions
⩥ What are thermophiles?
Answer: Organisms that thrive in high temperatures
, ⩥ What are psychrophiles?
Answer: Organisms that thrive in extreme cold temperatures
⩥ What are the characteristics of the eubacteria domain?
Answer: Single celled bacteria, prokaryotic cell structure, reproduce by
binary fission, DNA found on plasmids, movement is coordinated by
flagella or pili
⩥ What is a eubacteria cell wall composed of?
Answer: Peptidoglycan, may also have a sticky outer capsule
⩥ What is a eubacteria cell membrane made of?
Answer: Unbranched fatty acid chains attached to a glycerol via ether
linkages
⩥ True/false: eubacteria gave their own unique rRNA group different
than the Archea domain
Answer: True
⩥ Eubacteria are ____
Answer: Versatile
