Key Concepts
The objects of genetic analysis are prokaryotes and eukaryotes. The study is carried out by genetic modeling. The following genetic analysis methods are used.
- Hybrid method
- Genealogical
- Twin methods
- Somatic Cell Hybridization Methods
- Nucleic Acid Hybridization
- Tissue transplantation
- Analysis of transgenic and chimeric organisms
- Cytogenetic
- Biochemical
- Embryological
- Population
- Molecular
- Statistical and mathematical methods.
The choice of genetic analysis methods for objects of different levels of organization and depending on the tasks and levels of research.
Genetic Analysis Tasks
- identification of traits and genes to be examined
- gene localization, genetic mapping
- identification of gene function, establishing the nature of the mutation
- determination of what is regulated by the sign.
Study Levels
- molecular. At this level, nucleic acid is examined. Sequencing, biochemical methods are used (determination of the size of nanocrystals, melting point, communication with proteins)
- subcellular. Organelles with their own NK, as well as chromosomes, are being studied. Cytogenetic methods: microscopy, staining.
- cellular. “Ontogenetic” methods, that is, a study of how genetic information is realized at different levels at different stages of cell life.
- organismic. Mutation and recombination analysis, hybridological (genealogical), twin methods are used.
- population. Population analysis and statistical methods are used.
