 MICROBIAL GENETICS  Introduction • Genetics: is the science concerned with the cell characteristics, and how they are passed from one generation to the next. Gene: it is the unit of heredity.  It is a segment of DNA that carries, in its nucleotide sequence, information for specific biochemical or physiologic property. Phenotype:  All the heritable physical characters of the organism (Eye colour in humans, resistance to antibiotic in bacteria ….. etc.) Genotype:  It means the information in the DNA that control the phenotype. Compartments of microbial genetics curriculum  • Basic Genetics  • Genetic variation and gene rearrangements.  • Advanced genetics Molecules of Genetics • The main molecules of genetics are called nucleic acids. • All the genetic information are stored as a sequence of bases through nucleic acids mainly in DNA and in RNA in some RNA viruses. DNA (Deoxyribonucleic acid serves as organism’s genetic material. ...
