BIOL 1030: General Biology I

Discover what happens in your body after a hearty meal! Learn about the concept of 'distension' and how nerve cells act as messengers to your control center, orchestrating the digestive process.

In cell biology, the "driving ion" is a pivotal concept. It refers to ions moving from areas of high to low concentration, generating energy for various cellular transport processes. This gradient is crucial for nutrient uptake and waste elimination. Multiple processes involve a driving ion, including facilitated diffusion, symport transport, primary active transport pumps, and cotransport. Facilitated diffusion aids molecule movement along their gradient, while symport moves multiple substance

Unravel the origins of blood cell types as we differentiate between myeloid and lymphoid stem cells, highlighting the unique lineage of platelets, B cells, and Natural Killer cells.

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.

Nucleic acids, comprising DNA and RNA, are vital biomolecules encoding genetic information. We explore the structure and components of their monomers, nucleotides, emphasizing the role of nitrogenous bases and the significance of polynucleotide chains in storing genetic data.

Discover the properties and significance of methane (CH4), from its atomic structure to its pivotal role in industry and the environment. Uncover how carbon and hydrogen atoms form covalent bonds, making methane a key component of natural gas.
