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.
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.
2015 was the year of the phage—it marked the 100th anniversary of the discovery of the phage. Urmi Bajpai talks about her induction into the phage community and proposes that activities and simple experiments around phages should be included in school and college curricula.
