Cell Biology: Cellular organization, division and processes

By Prof. Shikha Laloraya   |   IISc Bangalore
Learners enrolled: 7085
This course focuses on cell organization, and the molecules and intracellular processes crucial for life and inheritance. A particular emphasis is on DNA transactions such as chromosome organization, replication, chromosome segregation, etc. Some examples of key discoveries in the field of cell cycle regulation, chromatin organization, and the dynamic processes and molecular machines involved in cell division will be discussed in detail. Other topics include Nuclear organization, Mitosis and Meiosis and cell death. In addition, cellular diversity will be discussed including selected specialized eukaryotic cells and their functions, cancer cells-how controls go wrong, and stem cells.
This course includes 2 modules of 10 lectures each. It is intended for graduate students mainly M.Sc. students (or 1st year Ph.D. students). Final year B.Sc. students may also find it useful.

Registration url: Announcements will be made when the registration form is open for registrations.
The online registration form has to be filled and the certification exam fee needs to be paid. More details will be made available when the exam registration form is published. If there are any changes, it will be mentioned then.
Please check the form for more details on the cities where the exams will be held, the conditions you agree to when you fill the form etc.


Average assignment score = 25% of average of best 6 assignments out of the total 8 assignments given in the course.
Exam score = 75% of the proctored certification exam score out of 100

Final score = Average assignment score + Exam score

YOU WILL BE ELIGIBLE FOR A CERTIFICATE ONLY IF AVERAGE ASSIGNMENT SCORE >=10/25 AND EXAM SCORE >= 30/75. If one of the 2 criteria is not met, you will not get the certificate even if the Final score >= 40/100.
