Summary of "Genetics, Genomics, and Precision Medicine - Past, Present and Future - April 28, 2020"

Scientific Concepts, Discoveries, and Nature Phenomena Presented

Genetics and Genomics
- Genetics: The study of genes and heredity.
- Mendelian Genetics: Gregor Mendel's work on inheritance patterns in pea plants, establishing foundational principles of Genetics.
- Emory Fisztics: Contributions to genetic laws of nature through sheep breeding.
- Evolution: Charles Darwin's theory of natural selection and descent from common ancestors.
Definition of Genes
- Gene: A unit of heredity made up of DNA that determines characteristics.
- Genotype vs. Phenotype
  - Genotype: The genetic makeup of an organism.
  - Phenotype: The observable characteristics of an organism.
Human Genome Project: A global initiative to sequence the entire human genome, providing essential data for understanding Genetics and disease.
Gene Expression
- Transcription and Translation: The processes by which genes are expressed to produce proteins.
- Central Dogma of Molecular Biology: The flow of information from DNA to RNA to proteins.
Sequencing Technologies
- Sanger Sequencing: Early method for sequencing DNA.
- Next-Generation Sequencing (NGS): Allows for rapid sequencing of millions of DNA fragments simultaneously.
- Third-Generation Sequencing: Directly sequences single DNA molecules, producing longer reads.
Transcriptomics: The study of RNA transcripts to understand gene expression and cellular processes.
- Techniques include microarrays and RNA sequencing.
Proteomics: The large-scale study of proteins, their functions, and interactions within biological systems.
Bioinformatics and Data Sharing
- Importance of data management and open access databases in genomics research.
- The role of bioinformatics in analyzing large datasets.
Future of Medicine
- The integration of AI and machine learning in healthcare.
- Blockchain technology for decentralized data management.
- Potential of DNA as a medium for computing.
