QCE BiologyPractice Examination 14

This paper covers

• Freshwater turtle chromosomal non-disjunction — karyotype interpretation, trisomy/monosomy, protein effect and phenotypic consequence
• DNA structure, semi-conservative replication, transcription and translation
• Gene and chromosomal mutations — types, causes and effects on protein structure and function
• Meiosis as a source of genetic variation — crossing over, independent assortment, non-disjunction
• Inheritance patterns — monohybrid, dihybrid, sex-linked and polygenic; Punnett squares and probability
• Gene expression regulation — epigenetic mechanisms and transcription factors
• Biotechnology — PCR, gel electrophoresis, recombinant DNA technology
• Natural selection types, allele frequency change and Hardy-Weinberg equilibrium
• Biodiversity measures — Simpson's Diversity Index, species richness, evenness
• Linnaean taxonomy, binomial nomenclature and molecular phylogeny including cladistics
• Ecosystem energy flow, trophic levels and ecological efficiency
• Biogeochemical cycling — water, carbon and nitrogen cycles
• Ecological niche, interspecific and intraspecific interactions, carrying capacity
• Primary and secondary succession through seral stages to climax communities
• Speciation modes, divergent and convergent evolution, adaptive radiation and extinction
