Course objectives:  
This course will enable the students to – 
1. Analyze terminologies related to chromosomes and their morphology, packaging of long  threads of DNA into the nucleus and the role of associated proteins in this process.  
2. Discriminate the structure and types of Nucleic acids, their characteristic features and  occurrence. 
3. Appraise the process and importance of DNA replication in both prokaryotes and eukaryotes  and protein machinery involved into it. 
4. Analyze the process of Transcription, Translation along with the mechanisms of post transcriptional and post translational processes in the cell.

Title

ZOL 213 

Molecular  Biology

The students will: 

CO 32: Relate different terminologies related  to chromosomes and their morphology,  packaging of a long thread of DNA into the  nucleus and the role of associated proteins in  this process.  

CO 33: Appraise the structure and types of  Nucleic acids, their characteristic features  and occurrence. 

CO 34: Develop detailed knowledge about  the process and importance of DNA  replication in both prokaryotes and  eukaryotes and protein machinery involved  into it. 

CO 35: Analyze comprehensive knowledge  about the process of Transcription,  translation along with the mechanisms of  post transcriptional and post-translational  processes in the cell.

The approach in  teaching: 

Interactive Lectures,  Discussion, Tutorials,  Reading assignments,  Demonstration, Guest  lectures 

Learning activities for  the students:
