Class No. 1  [5 academic hours]                     

Subject: Introductory Exercise
1. Overview of the Rules of classes – Students sign a sign-in sheet
2. Principles of microscopy techniques – PowerPoint 1

Subject: The structure of prokaryotic and eukaryotic cells

1. Powerpoint 2 – Gram positive versus gram negative
2. Powerpoint 3 - Prokaryotic vs. Eukaryotic cells - structure and function of cellular organelles /  Comparison of prokaryotic and eukaryotic cells

In the Lab

1. The structure of the eukaryotic cell – the organization of the nuclear genome
a. microscopic slides -  Comparison of human erythrocytes, frogs erythrocytes and chicken erythrocytes                 -  students draw EACH OF THE SLIDES under the microscope and notice the lack of the nucleus and genetic information in the human erythrocyte

Subject: The division of genetic material during cell divisions - mitosis and meiosis
1. Powerpoint 4 - The cell cycle (interphase, G1 phase, S phase, G2 phase, G0 phase) / The division of somatic cells – mitosis / The division of gamete cells – meiosis

In the Lab
1. Mitosis and Meiosis

cell division model - Comparison of mitosis and meiosis – Students properly arrange the sequence of mitosis and meiosis with the modelling kit, and draw the proper stages in their lab book

Subject -Introduction to genetic concepts & Mendelian Genetics  

1. Powerpoint 5 - Genetic material (location in the cell, chemical composition and structure of nucleic acids, functions, genetic code, codon, anticodon, intron, egsone, nucleosome)
2. Basic concepts of genetics (gene, allele, locus, phenotype, phenocopy, genotype, dominant and recessive trait, genome, chromosome, autosome, heterosome)
3. Mendel's Laws (Parentes cross, test cross, backcross)
4. Interaction of alleles (co-dominance, incomplete and complete dominance)
5. The interaction between genes (epistasis, complementation)
6. Pleiotropy
7. Lethal and sub-lethal genes
8. Poligenes, oncogenes
9. Gene conversion
10. Linkage genes, crossing – over, genetic distance

In the Lab

1. microscopic slide  The location of DNA and RNA in onion (Allium cepa) root tip cells
2. students draw the 4 stages of mitosis
