How Do I Become a Molecular Geneticist?

Molecular genetics is a branch of genetics that studies biological genetics and mutation mechanisms at the molecular level. The research topics of classical genetics are mainly about the transmission of genes between parents and offspring; molecular genetics mainly studies the nature of genes, their functions, and changes in genes. In the early studies of molecular genetics, microorganisms were used as materials. Its formation and development are closely related to microbial genetics and biochemistry.

In 1944, the American scholar Avery et al. First demonstrated that the conversion factor is DNA in diplococcus pneumoniae, thus clarifying that
1. Extraction of DNA and RNA: Human tissue cells are digested and degraded with proteinase K in a solution containing SDS, then extracted with phenol and chloroform, and the DNA is precipitated with ethanol. Ion exchange resins can also be used for rapid DNA extraction.
2. Southern blot hybridization analysis: This is a commonly used DNA molecular genetics research technology, named after the British scientist Southem. Can be used to determine specificity
