DNA AS GENETIC MATERIAL

By
Frederick Griffith: Bacterial transformation In 1928, British bacteriologist Frederick Griffith conducted a series of experiments using  Streptococcus pneumoniae  bacteria and mice. Griffith wasn't trying to identify the genetic material, but rather, trying to develop a vaccine against pneumonia. In his experiments, Griffith used two related strains of bacteria, known as R and S. R strain.  When grown in a petri dish, the R bacteria formed colonies, or clumps of related bacteria, that had well-defined edges and a rough appearance (hence the abbreviation "R"). The R bacteria were nonvirulent, meaning that they did not cause sickness when injected into a mouse. S strain.  S bacteria formed colonies that were rounded and smooth (hence the abbreviation "S"). The smooth appearance was due to a polysaccharide, or sugar-based, coat produced by the bacteria. This coat protected the S bacteria from the mouse immune system, making them virulent (capable of

HUMAN GENOME PROJECT

By
HUMAN GENOME PROJECT The Human Genome Project (HGP) was the international, collaborative research program whose goal was the complete mapping and understanding of all the genes of human beings. All our genes together are known as our "genome." Human Genome Project (HGP) was called a mega project. Goals of HGP Identify all the approximately 20,000-25,000 genes in human DNA. Determine the sequences of the 3 billion chemical base pairs that make up human DNA. Store this information in databases; Improve tools for data analysis; Transfer related technologies to other sectors, such as industries; Address the ethical, legal, and social issues (ELSI) that may arise from the project QUIZ HUMAN GENOME PROJECT
