The group of bacteria with simpler cell walls witha relatively large amount of peptidoglycan. Less toxic than gram-negative bacteria.
Gram-negative
The group of bacteria with a structurally more complex cell wall made of less peptidoglycan. More toxic than gram-positive bacteria.
Nucleotide region
The region in a prokaryotic cell consisting of a concentrated mass of DNA.
Binary fission
The type of cell division by which prokaryotes reproduce. Each dividing daughter cell receives a copy of the single parental chromosome.
Transformation
A prokaryotic cell takes up genes from the surrounding environment, allowing for considerable genetic transfer between prokayotes.
Conjugation
In bacteria, the direct transfer of DNA between two cells that are temporarily joined.
Transduction
A DNA-transfer process used by phages to carry bacterial genes from one host cell to another.
Plasmid
A small ring of DNA that carries accessory genes separate from those of a bacterial chromosome; also found in some eukaryotes, such as yeast.
Endospore
A thick-coated, resistant cell produced within a bacterial cell exposed to harsh conditions.
Antibiotic
A chemical that kills bacteria or inhibits their growth.
Photoautotroph
