Cell Theory - ACCURATE ANSWERS✔✔ all organisms are made of
cells, all existing cells are produced by other living cells, the cell is the
most basic unit of life
Prokaryotes - ACCURATE ANSWERS✔✔ Cells that do not contain
nuclei, bacteria and archaea
-singular circular chromosome
-no membrane bound organelles
-nucleolus
Archaea - ACCURATE ANSWERS✔✔ Domain of unicellular
prokaryotes that have cell walls that do not contain peptidoglycan
-live in harsh environments
Eukaryotes - ACCURATE ANSWERS✔✔ Cells that contain nuclei
,-multiple linear chromosomes in the nucleus
-extensive cytoskeleton
Central Dogma - ACCURATE ANSWERS✔✔ DNA-transcription-
RNA-translation-protein
Bacteria - ACCURATE ANSWERS✔✔ Domain of unicellular
prokaryotes that have cell walls containing peptidoglycan
Covalent bond - ACCURATE ANSWERS✔✔ A chemical bond that
involves sharing a pair of electrons between atoms in a molecule
Polar: uneven sharing
Nonpolar: even sharing
Ionic bonds - ACCURATE ANSWERS✔✔ Formed when one or more
electrons are transferred from one atom to another
Macromolecules - ACCURATE ANSWERS✔✔ any large molecules
made up of smaller molecules (monomers) joined together into a
polymer
, Condensation reactions - ACCURATE ANSWERS✔✔ a chemical
reaction in which two or more molecules combine to produce water or
another simple molecule
Hydrolysis - ACCURATE ANSWERS✔✔ Breaking down complex
molecules by the chemical addition of water
Nucleoid - ACCURATE ANSWERS✔✔ A dense region of DNA in a
prokaryotic cell.
Plasmids - ACCURATE ANSWERS✔✔ small circular DNA molecules
that replicate separately from the bacterial chromosome
Ribosomes - ACCURATE ANSWERS✔✔ site of protein synthesis
Cytoskeleton - ACCURATE ANSWERS✔✔ A network of fibers that
holds the cell together, helps the cell to keep its shape, and aids in
movement
-Prokaryotes have less extensive cytoskeleton
Cell wall - ACCURATE ANSWERS✔✔ a fibrous layer found outside
the plasma membrane of most bacteria and archaea and eukaryotes
