Topics for Biol 130 Test 3 (helpful to do relevant Ch. problems for self-testing) Mendelian Genetics Ch 14 understand concepts of standard dominance and recessivenes as well as variations (incomplete dominance, codominance, epistasis, polygenic, pleiotropy etc.) know specific examples of each Pedigree analysis: how to determine probable genotype (mode of inheritance) of offspring given pedigree phenotype Familiarity with discussed human genetic disorders karyotyping and fetal screening Chromosome abnormalities and Sex-linkage Ch 15 how to determine probability of inheriting a sex-linked gene What causes aneuploidy? Various ways chromosomes can be rearranged (we did not go over imprinting: not on test) Molecular basis of Inheritance Ch 16 Science history: know seminal discoveries relating importance of DNA (genotype) to phenotype and scientists who made discoveries (structure of DNA(Watson , Crick, Franklin), transformation (Griffiths, Avery et al.); Hershey-Chase experiment DNA synthesis: know Meselson and Stahl labeling experiment to determine mode of DNA replication (semi-conservative) Structure of nucleotides (deoxyribonucleotide and ribonucleotide) Ch 5 Mechanism of DNA replication: constituents, direction, products Be able to fill in a replication bubble with the appropriate daughter strands Examples of DNA proofreading and editing mechanisms Function of telomerase and telomeres where is telomerase activity found; how does it relate to cancer and longevity of cell's life Gene expression Ch 17 Mechanism and components of transcription & translation distinctions between between prokaryotes and eukaryotes (e.g. mRNA processing, coupled transciption & translation) How are secreted or membrane proteins synthesized: what role does SRP play Ability to read codon table for translation purposes, effects of mutations in DNA on transcription and translation products; memorize start and stop codons
