Transformation is the uptake of genetic material from the environment by bacterial cells. Genetics - Genetics - Microbial genetics: Microorganisms were generally ignored by the early geneticists because they are small in size and were thought to lack variable traits and the sexual reproduction necessary for a mixing of genes from different organisms. Transformation is the process of introduction of derived DNA fragments from a donor bacteria into a recipient bacteria. In molecular biology and genetics, transformation is the genetic alteration of a cell resulting from the direct uptake and incorporation of exogenous genetic material from its surroundings through the cell membrane(s). Genetic recombination. The studies of microorganisms involve studies of genotype and expression system. Typically the process requires a donor cell that at some point lysed and released naked DNA to the environment. Transduction is the transfer of genetic information from a donor to a recipient by way of a bacteriophage. Plastid genetic engineering is a safer, more precise, and more efficient transgene expression system than the nuclear genetic transformation system. Microbial Genetics.
