ЦТ Biology · Give each week a clear focus.

8 weeks · About 6 hours per week

Week 1

Your checkpoint

Week 2

Fundamentals of genetics: laws of heredity, variability, genetics of sex, selection & Molecular biology and genetic engineering: nucleic acids, gene expression, biotechnology

  • Explain the chromosomal basis of inheritance, including linked genes, crossing over, and sex-linked inheritance (color blindness, hemophilia)

  • Solve problems on sex determination and inheritance of sex-linked traits in humans and Drosophila

  • Describe the structure of DNA and RNA, and explain replication, transcription, and translation step by step

  • Outline the central dogma and the role of mRNA, tRNA, and rRNA in protein synthesis

  • Explain the principles of genetic engineering (restriction enzymes, vectors, PCR, gel electrophoresis) and give one example of a biotechnology application

Your checkpoint

A concept map linking DNA structure, replication, transcription, translation, and mutation, with 10 practice problems on sex-linked inheritance and molecular biology

Week 3

Metabolism and energy conversion in the cell (photosynthesis, chemosynthesis, energy metabolism, biosynthesis) & Reproduction and individual development of organisms (mitosis, meiosis, gametogenesis, ontogenesis)

  • Compare photosynthesis and chemosynthesis: light and dark reactions, pigments, and the role of ATP and NADPH

  • Describe the stages of aerobic and anaerobic respiration (glycolysis, Krebs cycle, electron transport chain, fermentation) and calculate ATP yield

  • Explain biosynthesis (protein synthesis, photosynthesis) and the role of enzymes in metabolic regulation

  • Outline the phases of mitosis and meiosis, and compare their outcomes and significance

  • Describe gametogenesis (spermatogenesis and oogenesis) and the stages of ontogenesis (embryonic and postembryonic development)

Your checkpoint

A comparative table of mitosis vs. meiosis and a flowchart of energy metabolism (glycolysis → Krebs → ETC) with ATP yields, plus 15 multiple-choice questions self-answered

Week 4

Botany: bacteria, fungi, lichens, algae, higher plants - structure, life cycles, taxonomy & Zoology: invertebrate and vertebrate animals - structure, physiology, taxonomy, ecology

  • Classify bacteria, fungi, lichens, algae, and higher plants according to their key structural and reproductive features

  • Describe the life cycles of mosses, ferns, gymnosperms, and angiosperms, and identify the dominant generation in each

  • Identify the main organ systems of invertebrates (sponges, cnidarians, worms, mollusks, arthropods, echinoderms) and vertebrates (fish, amphibians, reptiles, birds, mammals)

  • Explain the physiological adaptations of vertebrates to their environments (respiratory, circulatory, excretory systems)

Your checkpoint

A phylogenetic tree or classification chart of plants and animals, with 20 flashcards covering life cycles and key taxonomic features

Week 5

Human anatomy and physiology: organ systems, homeostasis, higher nervous activity, hygiene

  • Describe the structure and function of each human organ system (digestive, respiratory, circulatory, excretory, nervous, endocrine, immune, reproductive)

  • Explain the mechanisms of homeostasis (thermoregulation, blood glucose regulation, water balance) and the role of the nervous and endocrine systems

  • Outline the structure and function of the nervous system, including reflex arcs, synapse transmission, and the divisions of the brain

  • Explain higher nervous activity (conditioned and unconditioned reflexes, memory, sleep) and basic hygiene principles

Your checkpoint

A one-page summary sheet of each organ system with key functions and a diagram of a reflex arc, plus 25 practice questions on human physiology

Week 6

General biology: evolution, ecology, biogeocenology, biosphere and human impact & Biology as a science: methods of biological research, levels of organization of living matter

  • Summarize the main evolutionary theories (Darwin, synthetic theory) and the evidence for evolution (fossils, homology, embryology, molecular data)

  • Explain the mechanisms of evolution (mutation, genetic drift, gene flow, natural selection) and speciation

  • Describe the structure and function of ecosystems (food chains, trophic levels, energy flow, biogeochemical cycles) and the concept of biogeocenosis

  • Outline the biosphere and the impact of human activity (pollution, deforestation, climate change) on ecosystems

  • Describe the methods of biological research (observation, experiment, modeling, microscopy) and the levels of organization of living matter

Your checkpoint
