London School of Hygiene & Tropical Medicine

This module introduces students to fundamental biological principles in four key topic areas including (1) the evolutionary tree of life, (2) molecular biology and biochemistry, (3) cell biology and (4) immunology & vaccinology.

The overall module aim is to introduce students to the fundamental biological principles which are necessary for the Postgraduate Diploma and MSc in Infectious Diseases. Areas covered include: the evolutionary tree of life, molecular biology and biochemistry; cell biology and immunology and vaccinology.

Intended learning outcomes

Upon successful completion of the module a student will be able to: 

1. Identify and categorise evolutionary relationships between kingdoms and have a critical understanding of the features of prokaryotic and eukaryotic cells.
2. Explain the characteristics and roles of the basic molecules of life and demonstrate an understanding of the biochemistry that governs their interactions by creating new ways to represent the information.
3. Analyse the relationships between cellular components, structures and mechanisms to summarise specific cell functions.
4. Integrate knowledge of the main cell types, molecules and processes involved in the immune response with functional understanding to demonstrate how the various components act together to provide immunity to infection.

Assessment

This module is assessed by 2 x 2,500 word Assessed Assignments.

Mode of delivery

Our distance learning modules are delivered entirely online via directed self-study and online materials via the Virtual Learning Environment.

Module duration

Distance learning module studies begin at the start of October each year. Students may start their studies at any time once they gain access to Moodle (the virtual learning environment) and study materials, and work through the materials in line with the assessment schedules. The study year runs from the beginning of October through to June examinations. Some students also study between June and September with extended tutorial support (e.g. those undertaking projects, the Clinical Trials integrating report, or two of the Epidemiology modules). Deadlines for submission of coursework vary per programme but are usually in February, March, May, and September.

How you'll study

Our distance learning programmes are predominantly online and largely self-directed study to enable you to study independently and at times convenient to you. You'll have access to tutorial support and the ability to interact with other students and form study groups throughout the study year via the discussions in our Virtual Learning Environment, Moodle.
