Abstract
The course of Genetics is specifically designed for 2nd year Biological Sciences and Marine
and Continental Hydrobiology students.
The overall aim of this course, is to provide a clear, comprehensive, rigorous, and balanced
introduction to fundamental genetics. It is a guide to help students to:
• understand the basic concepts of genetics
• be able to make connections between the main concepts of genetics
• apply the concepts and the principles to solve problems of several types during tutorial
sessions, such as single-concept exercises that require application of definitions or the basic
principles of genetics, and quantitative problems that call for some numerical calculation.
The course comprises 11 chapters. Chapter 1 presents information about the genetic
material including DNA and RNA structures, DNA replication, organization of DNA in
chromosomes. Chapter 2 deals with cell cycle and cell divison. Chapter 3 covers the principles
of inheritance including Mendel’s laws, independent and linked genes, X-linked inheritance.
Chapter 4 deals with ordered tetrad analysis. Chapter 5 describes the mechanisms of genetic
transfer between bacteria. Chapters 6 and 7 deal with topics in molecular genetics including
transcription, translation and mutations. It is worth-mentioning that chapter 7 combined two
chapters (genic mutations and chromosomal mutations) into just one chapter, which is
mutations. Chapters 8 and 9 focus mainly on the structure of genes and control of gene
expression in both prokaryotic and eukaryotic oganisms. Chapter 10 presents
extrachromosomal genetics. Chapter 11 deals with some basic concepts of population genetics.
