Microbial Genetics

Microbiology 205 by Marguerite

Genetics the study of genes, how they carry information, how their information is expressed, and how they are replicated and passed to subsequent generations or other organisms.
Genome the genetic information of a cell
Chromosomes structures containing DNA (Deoxyribonucleic Acid) that physically carry heredity information
DNA exists in cells as a double-stranded helix, with the two strands held together by hydrogen bonds between specific nitrogenous base pairs
Adenine (A) paired with Thymine (T)
Cytosine (C) paired with Guanine (G)
Transcribe to produce messenger RNA (Ribonucleic Acid) known as mRNA
Genotype the genetic composition of an organism, i.e., its entire DNA
Phenotype the expression of the genes - its actual expressed properties.
Genomics the molecular characterization of genomes
Bacterial DNA is circular
Eukaryotic DNA is linear
Semiconservative after replication each double-stranded DNA molecule contains one original and one new strand
