BIO302 : Molecular Biology

Course Overview

Course Synopsis

This course is designed for graduate students who will explore basic concepts about molecular biology topics starting from nucleic acids (DNA and RNA), genes, genome and then finally up to the gene expression level. This course will enable the students to get sufficient knowledge about the subject to carry out research in the same field.

Course Learning Outcomes

Understanding the central dogma of molecular biology

  • After the successful completion of this course, students will develop basic knowledge and skills in molecular biology and become aware of the complexity and harmony of the cell. As you proceed through the modules, you will become able to apply this knowledge, skill, and awareness to topics such as: structure and functions of DNA/RNA and proteins, DNA/RNA extraction, PCR, recombinant DNA technology, blotting techniques, concept of gene and chromosomes, transcription, translation and DNA replication.
  • This course is aimed to provide ample knowledge to the students which is sufficient to fulfill the requirements of their BS degree. Students will be able to develop classical understanding about molecular biology. An important objective is to provide a supportive environment for students to cultivate higher order thinking skills by synthesizing concepts and by analyzing and interpreting different questions.
