BIOL 1110: Principles of Biology I

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.

Uncover the microscopic intricacies of compact and spongy bone structures. Learn about osteons, trabeculae, and the vital role of osteocytes. Dive into the balance of strength and functionality bones provide to our body.

Discover how humans adapt to cold environments through thermoregulation processes. Understand the body's heat conservation and generation mechanisms. Learn why certain physiological responses occur in cold conditions.

Discover the roles of sensory, interneurons, and motor neurons in the nervous system. These specialized cells transmit, process, and execute commands, orchestrating our responses. Experience the seamless coordination that enables us to interact with our environment.

Explore the world of spontaneous reactions, focusing on cellular respiration. Learn how our cells convert glucose into energy-rich ATP, driving vital life functions.

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.
