Document Summary
Iceland: introduction to themes of genetic information and the process of science, genetic relatedness b/c small population, low diversity b/c disease and natural disaster, low immigrants, decode, chapter (cid:883) and (cid:498)process of science overview(cid:499) Preformation fertilized egg = mini adult (homunculus) not true. Epigenesis organism develops from fertilized egg. Darwin criticized because lack understanding of genetic basis of variation and inheritance. Mendel peas, was not widely accepted. Many other duplicated and cited him later: transmission of traits, foundation for genetics (study of heredity and variation) Cell theory: all organisms are composed of basic units called cells, which are derived from preexisting structures. Chromosome theory of inheritance: inherited traits are controlled by genes residing on chromosomes faithfully transmitted through gametes, maintaining genetic continuity from generation to generation. Genetic material: avery, macleod, mccarty dna was genetic material. Nucleotides = nitrogenous bases (a, g, c,t: a=t, g---c (triple bond) Nucleic acid molecule (dna or rna), single or double-stranded, circular or linear: bacterial chromosomes.
