Working with autopsy brains of 11 children with autism and 11 children without the disorder who were between the ages of two and 15 years, the scientists focused on 25 genes responsible for specific nerve cell types in the outer layer for the brain, whatâs known as the cortex.
Cell division in Bacteria; in Eukaryotes. Two different mechanisms do this in cells: Bacterial cell fission, in which the circular chromosome is replicated. Eukaryotic cell cycle, including Mitosis, in which multiple linear chromosomes are separated and passed on.ell division in Bacteria; in Eukaryotes.

Bacteria - Growth of bacterial populations: Growth of bacterial cultures is defined as an increase in the number of bacteria in a population rather than in the size of individual cells. The growth of a bacterial population occurs in a geometric or exponential manner: with each division cycle (generation), one cell gives rise to 2 cells, then 4 cells, then 8 cells, then 16, then 32, and so forth.
