Many misconceptions can creep into an undergraduate student's mind as they study gene expression in their classrooms. In continuation with an earlier discussion on the common misconceptions in gene expression, in this article, educator Maya Murdeshwar from St. Xavier's College, Mumbai highlights some of the misconceptions around the process of translation – the process of building a polypeptide chain based on genetic information.
Problem-based learning is a pedagogical approach that enables students to learn scientific concepts in real-life contexts. In this article, Lakshmy Ramakrishnan, a researcher and educator, elaborates on this approach with examples and explains why it is so useful.
Molecular biology textbooks teach us that during gene expression, only one strand of DNA is used to synthesize RNA. Does this mean that only one of the strands of an entire DNA duplex is functional? What does the other strand do? Which one is called the 'sense' strand? Is it the same as the 'template' strand? These are some questions that often baffle undergraduate students of biology. In this article, educator Maya Murdeshwar of St. Xavier's College, Mumbai describes how she approaches these concepts in her classroom.
Many biological phenomena, like respiration, osmoregulation or nerve conduction, have basis in physical processes like diffusion and osmosis. Definitions and diagrams may contain nuances that students may miss, especially when these are not viewed through the lens of physics. In this article, Nagarjuna G., Former Professor, Homi Bhabha Centre for Science Education, TIFR gives examples of some of these misconceptions and offers simple simulations to provide a more accurate picture of these processes.
Social media platforms, such as Twitter, are increasingly being used by scientists to share their ideas and findings with a global audience. Younger users, such as #undergraduate students, could benefit from engaging with these messages, in more than one ways. In this article, @AndreaPhillott, a Professor of #ConservationBiology at FLAME University, Pune, describes how her students benefitted from an assignment with Twitter.
