  • What is Genetics: The Study of Biological Information Chapter 1 The Science of heredity( 형질유전 ): explains the biological structures and mechanisms about what is inherited and how
  • Chapter Outline
    • DNA molecules encode the biological information fundamental to all life forms (organisms)
    • Proteins are the primary unit of biological function
    • Regulatory networks (DNA-protein, protein-protein) specify the behavior of genes
    • All living things are closely related (evolutionarily conserved)
    • Genomes are modular, allowing rapid evolution
    • Genetic techniques allow us to dissect biological complexity
  • Information in DNA molecules generates diversity in species: The key features are summarized
    • Four bases – G (guanine), A (adenine), T (thymine), and C (cytosine) are the nucleotide building block of DNA
    • DNA is a double stranded helix composed of A-T and G-C complementary bases
    • Order of nucleotide sequences determine which proteins are synthesized, as well as when and where the synthesis occurs.
    Fig. 1.1a
  • Information in DNA generates diversity (continued)
    • All organisms use the same basic genetic language (genetic code)
    • The differences:
    •  are contents, amount of information, and time, places of gene expression
    Fig. 1.1a
  • Genes are sequences of DNA that encode proteins
    • Antiparallel structure of DNA strands means that the two complementary strands are oriented in opposite direction
    Fig. 1.2 Exon Intron Most of eukaryotic genes are defined as specific combinations of exons
  • DNA resides in within cells packaged as units called chromosomes
    • The entire collection of chromosomes in each cell of an organism is called a genome
    • Humans have 46 chromosomes
    • The human genome has about 3 x 10 9 (3 billion) base pairs and 40,000 – 60,000 genes
    Fig. 1.4
  • Biological function emerges primarily from proteins: enable to reproduce, move and adapt to environments Figure 1.5a
  • What is protein’s properties?
    • Proteins are polymers of amino acids
    • Proteins have three dimensional structures
    • Information in DNA dictates the sequence of its amino acids
    • There are 20 different amino acids
    • The order of amino acids determines the type of protein and its structure
  • Proteins interact with DNA and proteins
    • Biological systems function as complex interactive networks of proteins and DNA that interact with one another
    • You have to analyze the complex network to understand how learning and memory can be
    Fig. 1.6  Human brain: 10 11 neurons with 10 18 synapses
  • Evidence (1) for the common origin of all living things
    • DNA sequences use the same arbitrary genetic code: various triplet groupings of 4 letters (A, T, G, C) encode the 20 letters of amino-acid alphabet
    • RNA is composed of four bases: guanine (g), adenine (a), cytosine (c), and uracil (u)
    Fig. 1.7b  Central dogma: DNA  RNA  Protein
    • Comparisons of many genes with same functions: show striking similarity among all organisms
    • Human cell-cycle genes replace the normal function of yeast homologs (related genes)
    Fig. 1.8 Evidence (2) for the common origin of all living things Comparisons of the cytochrome C protein in six species: electron donors/acceptors during cellular respiration
  • Genetic study using model organisms is important for the study of human genes
    • Studies of genetics in model organisms help us understand how genes work in humans
    • Some model organisms include bacteria, yeast , roundworms , fruitflies , and mice.
    • Model organisms may have simpler biological networks and can be manipulated experimentally.
  • Genetic techniques permit the dissection of complexity
    • Dissection of genomes gene-by-gene unravels the complexity of biological systems ( Genome sequencing projects )
    • The challenge for modern biology: shift from the analysis of single units to the analysis of complex system
    •  By now “Systems Biology” is emerging as one of main biology fields
    • Genetics provides unique tools to solve this challenge
    Fig.1.12: Five model organisms: their genomes are sequenced
  • Genetics is a leading scientific field for Predictive and Preventative Medicine
    • Discovery of genes with variations that cause or predispose disease will continue at a rapid pace.
      • Gene therapy
      • Diagnostics
      • Therapeutic drugs to block or reverse effects of mutant genes (Gleevec)
      • Detection of disease and treatment before onset may increase life span significantly
