Why do bacteria divide?
The problem of not only how but also why cells divide can be tackled using recent ideas. One idea from the origins of life - Life as independent of its constituents - is that a living entity like a cell is a particular pattern of connectivity between its constituents. This means that if the growing cell were just to get bigger the average connectivity between its constituents per unit mass - it...
متن کاملWhy Do Plant Cells Divide ?
Axial, meristematic growth imposes a unique set of constraints upon cell behavior during plant development. Owing to the perpetually embryonic nature of meristematic activity, cell division plays a relatively more constant role throughout development in higher plants than it does in animals. During early embryogenesis in Arabidopsis, for example, stereotyped, formative cell divisions block out ...

متن کاملWhy do bacteria engage in homologous recombination?
Microbiologists have long recognized that the uptake and incorporation of homologous DNA from outside the cell is a common feature of bacteria, with important implications for their evolution. However, the exact reasons why bacteria engage in homologous recombination remain elusive. This Opinion article aims to reinvigorate the debate by examining the costs and benefits that homologous recombin...
متن کاملDo HSCs divide asymmetrically?
Hematopoiesis is maintained by stem cells with the ability to both self-renew and to give rise to differentiated progeny. A proper balance between these fates is essential to prevent hematopoietic failure or uncontrolled stem cell expansion. So how do HSCs undergo self-renewal? In theory, this can occur in 2 ways; either through symmetrical cell division (SCD) where 2 new stem cells are formed,...
