Microbial Genetics
Microbiology 205 by Marguerite
Term | Description |
---|---|
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 |
