The Ted Talk video entitled “Animations of Unseeable Biology” describes the process of DNA replication. As the speaker Drew Berry explains‚ this process is repeatedly occurring and is performed mechanically. He provides us an animation of how a chromosome is replicated and split with the help of microtubules. Microtubules are straight tubes that are made up of proteins and it resides within a cell. This hollow tube allows the mitosis phase to occur. The copying of DNA is transported across the microtubules

Advanced Cell Biology II Step 1: How will you identify the “vital” cellular protein that the virus targets for degradation? (Hint: think proteomics). (3 pts.) First‚ since we know the viral RNA sequence and its targeting protein‚ we can investigate it in bioinformatics database‚ and can acquire some clues or hints about the target proteins. From the bioinformatics database‚ we might be able to find its structure‚ similarity with other proteins‚ functions‚ and binding domains. In other words

Biology 102 Lab Report: Ventilation and Oxygen Consumption in Fish Methods: The lab consists of two experiments repeated over a period one hour with fifteen minutes interval‚ in order to determine the effect of weight and temperature on ventilation and oxygen consumption of Carassius auratus‚ commonly known as goldfish. Each experiment was carried out by five groups. Measurement of ventilation was determined by recording operculum movement of the fish. Oxygen consumption was measured using oxygen

Biology Vocabulary: 1. Immigration: influx of individuals into an area 2. Emigration: movement of individuals out an area. 3. Logistic growth: (shown with an S-shaped curve) population growth that levels off at carrying capacity. 4. Exponential growth: (shown as J-shaped curve) geometric increase of a population as it grows into an ideal unlimited environment. 5. Niche: the sum total of a species use of the abiotic and biotic resources in its environment 6. Symbiosis: an ecological relationship

The disease is most common in places with poor sanitation‚ crowding‚ war‚ and famine. Transmission: (reference 1) When humans ingest cholera bacteria‚ they may not become sick themselves‚ but they still pass the bacteria in other ways such as contaminating food or water supplies‚ which can serve as ideal breeding grounds for the cholera bacteria. Cholera usually isn’t transmitted
