This seminar presentation discusses bio molecular computing. It explains that bio molecular computing uses biological molecules like DNA instead of silicon chips for computing. It works by pairing DNA bases and using enzymes to cut or splice DNA molecules. While bio molecular computing has potential advantages in terms of memory, it also faces challenges like being resource intensive, producing errors, and not allowing easy transmission of information. Whether bio molecular computing becomes practical will depend on overcoming these challenges and finding applications where it has clear advantages over traditional computing.
