BISC 120: General Biology: Organismal Biology and Evolution

Explore stromatolites, the oldest indicators of life on Earth formed by microbial actions. Understand their presence in shallow marine environments and their connection to early eukaryotic life.

Explore the world of microbiology in this video as we investigate the processes that lead to genetic variation in bacterial populations. Learn about transduction, transformation, conjugation, and mutation, and discover why meiosis, a process occurring in sexually reproducing organisms, is not a source of genetic variation in bacteria.

Explore the pivotal role of enhancers in gene expression as we dissect their function and interaction with transcription factors. Gain insights into how they crucially influence the transcriptional control of genes.

In this video, we explore the crucial role of the cytoplasm in a cell and its division. By drawing parallels to intriguing concepts like telekinesis, we shed light on vital processes like karyokinesis and cytokinesis. By the end, we unveil cytokinesis as the primary method for plant cell cytoplasm division.

Explore the groundbreaking heterotroph hypothesis by Alexander Oparin. This video outlines how the first organisms likely consumed pre-existing organic matter reshaping how we think about the origins of life and evolution

Discover the multifaceted role of cytokines as the body's cellular messengers. Uncover their pivotal tasks in regulating immune and inflammatory responses. Dive into their significance in cell growth, differentiation, and inter-cellular communication.
