BIOL 107: General Biology

Unravel the intricate relationship between histones and DNA. Learn how histones maintain DNA structure within the cell nucleus and understand the significance of charge attractions in DNA-histone binding.

Explore the underlying causes of muscle fatigue and the crucial role of lactic acid. Understand the impact of ATP depletion and anaerobic metabolism on muscle performance. Gain insights into planning effective exercise and recovery strategies.

Learn about muscle fascicle patterns and their role in human anatomy. Our video zeroes in on the convergent pattern found in the pectoralis major. Compare this with other muscle types like the biceps brachii and gluteus maximus to deepen your anatomical knowledge.

Explore what makes each element unique by focusing on the atomic components: protons neutrons and electrons. Learn why the number of protons known as the atomic number is the defining characteristic for each element's properties. Understand how protons set elements apart even as neutrons and electrons also play important roles.

Discover the unique adaptations of C4 and CAM plants in photosynthesis. Understand their evolved strategies to fix carbon efficiently in challenging environments. Dive into nature's remarkable mechanisms of survival and adaptation.
