QCE BiologyPractice Examination 12

This paper covers

• Koala epigenetics and habitat fragmentation — stress-induced chromatin remodelling and immune gene transcription
• DNA structure, semi-conservative replication, transcription and translation
• Epigenetic regulation: DNA methylation, histone modification, chromatin remodelling
• Gene expression regulation via transcription factors
• Biodiversity measurement: Simpson's Diversity Index, species richness, evenness
• Linnaean taxonomy, binomial nomenclature, molecular phylogeny and cladistics
• Ecosystem dynamics: energy flow, trophic levels, biogeochemical cycling
• Ecological niches, interspecific interactions, carrying capacity
• Primary and secondary succession
• Meiosis as a source of genetic variation
• Inheritance patterns: monohybrid, dihybrid, sex-linked, polygenic
• Gene and chromosomal mutations
• Natural selection types and microevolutionary change
• Hardy-Weinberg equilibrium and allele frequency
• Speciation modes, divergent and convergent evolution, adaptive radiation
• Biotechnology: PCR, gel electrophoresis, recombinant DNA
• Fossil, molecular and phylogenetic evidence for macroevolution
