Summary module description:

Molecular genetics, the study of the structure and function of genes and genomes, enabled scientists to develop new technologies that impact many aspects of our lives. The understanding of how genes and genomes work revolutionized research and led to the development of personalized medicine and contributed to improved agricultural and industrial production. In this module you will study how chromosomes are organised, replicated and repaired, and how genes are expressed and regulated at the molecular level. The core concepts of molecular genetics will be linked with a range of topics with relevance to today’s society. You will learn about recombinant DNA technology, genetic engineering, and gain hands on experience of the techniques used in the laboratory for molecular cloning. You will also use bioinformatics approaches to analyse genes and their encoded proteins at the molecular level.

Aims:

The main aim of this course is to give students an in-depth understanding of molecular genetics that underlies the majority of modern biological research. The module will cover both the concepts and some applications of molecular genetics in the study of processes in prokaryotic and eukaryotic organisms.

The module aims:

1. To provide an appreciation of the mechanisms involved in the control of gene expression in both eukaryotes and prokaryotes.


2. To give an overview of new genetic technologies that advance our understanding of genetic mechanisms and to develop understanding of the major concepts used by these applications.


3. To provide students with hands-on experience and understanding in some of the main procedures used in recombinant DNA technology and protein expression work, through performing laboratory exercises


4. To provide an illustration of the link between experimentation and scientific knowledge.


5. To introduce students to important bioinformatics tools used to study gene and protein function.


6. To provide students with the analytical skills required to experimental design, data analysis and interpretation.

Assessable learning outcomes:

1. Comprehend the manner in which chromosomes are organised, structured and replicated.


2. Describe the mechanisms gene expression control for classic bacterial and eukaryotic exemplars.


3. Understand the processes of gene expression in eukaryotes and prokaryotes.


4. Compare and contrast the mechanisms employed for control of gene expression in eukaryote as opposed to prokaryote systems.


5. Comprehend a range of experimental technologies and current topics in molecular genetics.


6. Understand the use of bioinformatics as a tool in examining nucleotide and amino acid sequence data.Ìý


7. The ability to perform and analyse the results of key methods in molecular genetics; to understand the principles of such methods.

Additional outcomes:

1. To develop skills in bioinformatics.


2. Develop problem solving skills in molecular genetics during tutorial sessions.


3. Students will have developed their team-working skills and have a deeper understanding of molecular biology through the application of practical approaches.

Outline content:

1. Chromosome and chromatin structure


2. The process of DNA replicationÌý


3. The basal transcription machinery in prokaryotes and eukaryotes


4. The involvement of chromosome structure in gene expression


5. The involvement of protein-nucleic acid interactions in control of gene expression


6. Response of genes to external stimuli illustrated by appropriate examples and the mechanisms used to switch on and off genes to integrate the effects of varying stimuli


7. RNA processing


8. Introducing applications of the basic principles and techniques of molecular genetics in different fields from fundamental research to human medicine.


9. Bioinformatics analysis of gene function


10. Problem-solving studies of gene function using bioinformatics


11. Laboratory practical sessions: Molecular cloning and recombinant protein expression using methods of PCR, restriction digestion, transformation and bacterial expression of proteins.

Brief description of teaching and learning methods:

1. Most weeks will include two ~45-minute lectures.


2. Problem-solving tutorials or bioinformatic 'practical' sessions (assessed) may follow the lectures.


3. Required background reading/learning materials will form part of the assessed content of the module.


4. Two assessed Blackboard-based tests performed will be performed in students own time; these will be based upon the content of the module (to encourage revision and comprehension of the course).


5. In addition, there will be a series of assessed lab-based practical sessions where students will engage with a number of recombinant DNA techniques.


6. For lab-based practical sessions:
   
   
   
   1. students will be expected to complete preparatory work beforehand and this will be assessed before the start of the module by a test,
   
   
   2. lab-based practical work will be in carried ou t either individually or in groups of varying sizes depending on the task involved,
   
   
   3. understanding gained will be assessed at the end of the practicals.

Summative assessment- Examinations:

Two hours written exam.

Summative assessment- Coursework and in-class tests:

• Four Blackboard tests on lecture content with 5% weight of each in the final mark


• One Blackboard test on laboratory practical content with 20% weight of each in the final mark


• Four Blackboard tests on bioinformatics practical sessions’ content with 2.5% weight of each in the final mark

Formative assessment methods:
Work which provides opportunities to improve performance (e.g. through feedback provided) but which does not necessarily always contribute towards the overall module mark.

Tutorial sessions

Penalties for late submission:

The Support Centres will apply the following penalties for work submitted late:

• where the piece of work is submitted after the original deadline (or any formally agreed extension to the deadline): 10% of the total marks available for that piece of work will be deducted from the mark for each working day (or part thereof) following the deadline up to a total of five working days;
• where the piece of work is submitted more than five working days after the original deadline (or any formally agreed extension to the deadline): a mark of zero will be recorded.

The University policy statement on penalties for late submission can be found at: /cqsd/-/media/project/functions/cqsd/documents/cqsd-old-site-documents/penaltiesforlatesubmission.pdf
You are strongly advised to ensure that coursework is submitted by the relevant deadline. You should note that it is advisable to submit work in an unfinished state rather than to fail to submit any work.

Assessment requirements for a pass:
A mark of 40% overall
