Penicillin-binding protein 2a or PBPs are protein produced by bacteria that binds with the β-lactam antibiotics such as penicillin. They play role in the cell wall synthesis of bacteria by producing peptidoglycan by catalyzing the reaction.
β-Lactam antibiotics bind with the PBPs and cause the disruption to peptidoglycan cross-linking in the biosynthesis of the cell wall and ultimately lysis of bacteria takes place and cell death.
Meiosis is the process of reduction of diploid cells to haploid cells and it involves two process meiosis 1 and meiosis 2.
Meiosis 1 involving the crossing over of the genetic material between the pair of chromosomes whereas meiosis 2 involves the separation of the chromosomes into sister chromatids.
