Molecular Biology introduces you to the structure and function of molecules, including DNA and RNA, which allow genes to be expressed and be maintained from one generation to the next. You will also learn about genetic engineering, its application, and the ethical issues associated with its use.
To provide a general introduction to the molecular basis of genetics, how genes are maintained from one generation to the next and how their expression is regulated in various systems.
Students will understand the basis of genome maintenance and gene expression, and appreciate the concept of mutation at the level of the genotype and how this manifests at the phenotypic level. The major concepts and principles underlying recombinant DNA technology will be understood, along with major applications and associated issues relating to the public understanding of science.
Part I - Structure, Function and Replication of DNA
• DNA as the heritable material
• Structure of DNA
• DNA replication: semi-conservative replication, DNA polymerases, events at the replication form, replication of the lagging strand, telomeres, consequences of defects in telomerase.
• Replication of genomes: origins of replication, control of DNA replication.
• Structure of chromosomes: DNA packaging, features of metaphase chromosomes.
Part II - Gene expression
• From DNA to RNA: the structure and function of the gene, promoters and terminators. Transcriptional initiation, elongation and termination, RNA polymerases
• Structure, function and Biochemical properties of RNA
• From RNA to Protein: the genetic code, codons & anticodons, the ribosome & translation
• Gene expression in Prokaryotes: the Lac operon
• Gene expression in Eukaryotes: regulation of transcription, promoters, enhancer elements; RNA spl
- Analytical skills
- Some areas of the online assessment and exam questions require analytical skills.
- Problem solving
- Some areas of the online assessment and exam questions require problem solving skills.
- Students must complete eLearning assessments based on lecture material and supplementary lecture-related material. Research and reading is required to complete these. There is a voluntary competition where students must identify, and describe unknown molecular structures.
Examination (90%) and an eLearning exercise (10%).
An eLearning component of the unit assessment allows students to monitor their own progress since this incorporates a formative assessment element. An additional formative eLearning exercise will allow students to practice MCQs based on various parts of the lecture unit. A formative online peer-authored MCQ exercise "Peerwise" will run for the course of the unit. An online discussion forum is available for communication between students and staff. An online interactive feedback and revision surgery is operated.
