Study Notes

Molecular Genetic Techniques

  • Primary focus of Molecular Genetic Techniques Part I and II: analyzing and manipulating genetic material at the molecular level

Recombinant DNA Technology

  • Function: enables the creation of new DNA molecules by combining different DNA sequences from different sources
  • Allows for the introduction of desired traits into organisms, gene expression, and protein production

Recombinant DNA

  • Definition: a form of DNA that is created by combining genetic material from different sources, such as different organisms

Nucleases in Molecular Genetics

  • Main function: to cut DNA molecules at specific recognition sites, facilitating the manipulation of genetic material

DNA Cloning

  • Involves: creating multiple copies of a DNA segment, typically using a vector (e.g. plasmid) to replicate the desired DNA sequence in a host organism
