WebIn the tailed bacteriophages, DNA is packaged into spherical procapsids, leading to expansion into angular, thin-walled mature capsids. In many cases, this maturation is accompanied by cleavage of the major capsid protein (CP) and other capsid-associated proteins, including the scaffolding protein (SP) that serves as a chaperone for the … WebMar 30, 2024 · The cleavage furrow forms around the division plane which eventually pinches off separating the cell into two cells. This is followed by a process of contraction and constriction by the contractile ring, made up of actin, myosin, and regulatory proteins.
