Course Synopsis

In this course, starting from the nature of chromosomes, DNA and RNA, student will be exposed to nucleic acid sequencing and processes of transcription and translation. This course is designed to distill in comprehensible way, the mysteries of recombinant DNA technology and its role in biotechnology. This course aims to let the students know about contribution of recombinant DNA technology to our understanding of gene function, biological processes and human genetics. In this course DNA cloning methods, site directed mutagenesis, PCR, RFLP and other related techniques will be discussed in detail.
