Unformatted text preview: MICROBIAL GENETICS Genetics is the science of heredity. It includes: • What are genes • How do they carry information • How are they replicated (copied) • How are they passed to subsequent generations of cells • How are they passed from organism to organism • How does their expression determine the characteristics of the organism A gene is a segment of DNA that codes for a functional product. Genome—alll the genes of an organism Chromosomes are DNA molecules that contain the genes. A DNA molecule consists of linked nucleotides. Each nucleotide consists of: • Pentose (5-carbon) sugar called deoxyribose • Phosphate group • Nitrogenous base Adenine- - - - - - -Thymine Cytosine- - - - - - - Guanine A DNA molecule is described as a double helix. Double---this means that there are two strands of linked nucleotides. The structure can be Double---this means that there are two strands of linked nucleotides....
