The ribosome monomer is 70s with two subunits, 30s and 50s.
C. Polyamines They are of three types
. Putrescin . Spermidine .Spermine It is found in association with bacterial DNA, ribosomes and cell membrane.
Function of polyamines
Prevent dissociation of 70s ribosome into subunits.
Increase resistance of protoplast lysis.
. represent accumulated food reserves. Nature of granules . Glycogen . Poly-beta hydroxy butyrate . Babes-ernst (Volutin)
E. Nuclear apparatus Well defined nucleus and nuclear membrane , discrete chromosome and mitotic apparatus are not present in bacteria ; so nuclear region of bacteria is named as nuclear body, nuclear apparatus and nucleoid.
