New model for reproduction of E. coli bacteria

With a new model, AMOLF researchers reveal how single-celled organisms like bacteria coordinate growth, cell division and DNA replication. Bacteria reproduce via growth and cell division. During each cycle of growth and division, ...

Evidence for new theory of genetic recombination

In most higher organisms, including humans, every cell carries two versions of each gene, which are referred to as alleles. Each parent passes on one allele to each offspring. As they are linked together on chromosomes, adjacent ...

Model organism

A model organism is a species that is extensively studied to understand particular biological phenomena, with the expectation that discoveries made in the organism model will provide insight into the workings of other organisms. In particular, model organisms are widely used to explore potential causes and treatments for human disease when human experimentation would be unfeasible or unethical. This strategy is made possible by the common descent of all living organisms, and the conservation of metabolic and developmental pathways and genetic material over the course of evolution. Studying model organisms can be informative, but care must be taken when generalizing from one organism to another.
