生物考试大纲及试卷组成

生物考试大纲及试卷组成 I. CELLULAR AND MOLECULAR BIOLOGY (33-34%) Fundamentals of cellular biology, genetics and molecular biology are addressed. Major topics in cellular structure and function include metabolic pathways and their regulation, membrane dynamics and cell surfaces, organelles, cytoskeleton, and cell cycle. Major areas in genetics and molecular biology include chromatin and chromosomal structure, genomic organization and maintenance, and the regulation of gene expression. The cellular basis of immunity and the mechanisms of antigen-antibody interactions are included. Distinctions between prokaryotic and eukaryotic cells are considered where appropriate. Attention is also given to experimental methodology. Cellular Structure and Function (16-17%) Biological compounds Macromolecular structure and bonding Abiotic origin of biological molecules ? ?? ?? ?? ?? ?? ?? ?? ? Enzyme activity, receptor binding and regulation Major metabolic pathways and regulation Respiration, fermentation and photosynthesis Synthesis and degradation of macromolecules Hormonal control and intracellular messengers ? ?? ?? ?? ?? ?? ?? ?? ?
