Description - summary of the module content

Module description

From genes to genetics. What did Mendel and Darwin not know? Find out in this lecture course that takes us all the way from the structure of genes to how they behave in natural populations.

Learn about current applications for genetics and DNA sequencing in a series of special lectures on butterfly mimicry and bacterial genetics.

Practise your new found knowledge in a series of practicals ranging from Polymerase Chain Reaction to virtual genetics.

Module aims - intentions of the module

This module introduces you to core concepts in genetics. Genetics is fundamental to any understanding of the biosciences and underpins any Single Honours degree in the subject. The module also aims to provide you with the basic information on cell and molecular mechanisms that will enable you to take Stage 2 and 3 modules in the Cell and Molecular Sciences.

The module will give you career-relevant skills in Bioinformatics and Molecular Biology which are both rapidly expanding employment opportunities. The module will also expose you to research-led teaching by using real examples from ongoing research in our department and others. Genetics research involving staff members in the Centre for Ecology and Conservation will be highlighted.

Intended Learning Outcomes (ILOs)

ILO: Module-specific skills

On successfully completing the module you will be able to...

  • 1. Illustrate how information is stored and expressed in cells, including understanding the differential roles of genes and the environment on expression of a phenotype
  • 2. Analyse the effects of major genes by inspection of phenotypes and demonstrate an understanding of the molecular basis of variation and mutation, of natural genetic recombination, and of genetic analysis and its importance in biology
  • 3. Explain the behaviour of genes in populations
  • 4. Illustrate a knowledge and understanding of genetics

ILO: Discipline-specific skills

On successfully completing the module you will be able to...

  • 5. Describe essential facts and theory across a sub-discipline of biosciences
  • 6. Identify critical questions from the literature and synthesise research-informed examples into written work
  • 7. Identify and implement, with some guidance, appropriate methodologies and theories for addressing a specific research problem in biosciences
  • 8. With guidance, deploy established techniques of analysis, practical investigation, and enquiry within biosciences
  • 9. Describe and begin to evaluate approaches to our understanding of biosciences with reference to primary literature, reviews and research articles

ILO: Personal and key skills

On successfully completing the module you will be able to...

  • 10. Develop, with guidance, a logical and reasoned argument with sound conclusions
  • 11. Communicate ideas, principles and theories using a variety of formats in a manner appropriate to the intended audience
  • 12. Collect and interpret appropriate data and undertake straightforward research tasks with guidance
  • 13. Evaluate own strengths and weaknesses in relation to professional and practical skills identified by others
  • 14. Reflect on learning experiences and summarise personal achievements
  • 15. Work in a small team and deal proficiently with the issues that teamwork requires (i.e. communication, motivation, decision-making, awareness, responsibility, and management skills, including setting and working to deadlines)

Syllabus plan

Syllabus plan

Lectures will cover:

The discovery of DNA and RNA; structure of bases, nucleotides and polynucleotides; evidence for function of DNA as genetic material; evidence for DNA structure; implications of DNA structure; general structure of RNA; survey of types of RNA; general aspects of RNA synthesis; the genetic code; synthesis and processing of mRNA; rRNA and ribosomes; tRNA.

The differences between phenotype and genotype, and the way in which phenotype is affected by both genetic and environmental effects.

The analysis of major genetic differences in eukaryotes, including linkage, sex linkage and epistasis. The statistical analysis of segregation ratios.

Extrachromosomal inheritance.

Population genetics: the concept of the gene pool and the Hardy-Weinberg law; changes in gene frequency by selection and drift; neutral and Darwinian evolution; speciation.

Practical sessions will reinforce concepts covered in lectures, emphasising the nature of scientific enquiry.

Re-assessment notes

Deferral – if you miss an assessment for certificated reasons judged acceptable by the Mitigation Committee, you will normally be either deferred in the assessment or an extension may be granted. The group problem set is not deferrable because of its group nature. The mark given for a re-assessment taken as a result of deferral will not be capped and will be treated as it would be if it were your first attempt at the assessment.

Referral – if you have failed the module overall (i.e. a final overall module mark of less than 40%) you will be required to sit a further examination. The mark given for a re-assessment taken as a result of referral will count for 100% of the final mark and will be capped at 40%.
