Cell Cytoskeleton: Structure, Functions, Types & NEET Biology Notes

Botany Sir Himansu
Cell Cytoskeleton: Structure, Functions, Types & NEET Biology Notes Quick Answer: The cytoskeleton is a dynamic network of protein filaments present inside cells. It helps maintain cell shape, organize cellular components, enable movement and participate in cell division and intracellular transport. For NEET Biology, the three major components to remember are microtubules, microfilaments and intermediate filaments . NEET Quick Fact: The cytoskeleton is not a rigid framework. It is a dynamic protein network that can assemble and disassemble according to the needs of the cell. What Is the Cytoskeleton? The cytoskeleton is an organized network of protein fibers distributed throughout the cytoplasm of eukaryotic cells. It provides structural support while also helping the cell perform important dynamic activities such as movement, intracellular transport and chromosome separation during cell division. Unlike the name may suggest, the cytoskeleton is not equivalent...

Biodiversity Hotspots in India: Number, Names, Locations & NEET Biology Notes

Botany Sir Himansu
Biodiversity Hotspots in India: Number, Names, Locations & NEET Biology Notes Quick Answer: India has parts of four global biodiversity hotspots : the Himalaya, Indo-Burma, Western Ghats–Sri Lanka, and Sundaland . The Indian portions of these hotspots are important because they contain high biodiversity, many endemic species and ecosystems under significant threat. For NEET Biology, biodiversity hotspots are an important topic because they connect the concepts of biodiversity, endemism, species richness, conservation and threats to biodiversity . NEET Quick Fact: India is associated with four global biodiversity hotspots: Himalaya, Indo-Burma, Western Ghats–Sri Lanka and Sundaland. What Is a Biodiversity Hotspot? A biodiversity hotspot is a biologically rich region that contains a large number of endemic species and is facing a high degree of habitat loss or other threats. The idea of biodiversity hotspots is used to identify regions where conservation efforts c...

Precision Medicine in the USA: How Genetics Is Changing Personalized Healthcare What if healthcare could be tailored more closely to the biology of each patient? That is the basic idea behind precision medicine. Precision medicine considers differences between people, including their genes, environment and lifestyle , when researchers and healthcare professionals think about disease prevention, diagnosis and treatment. The NIH describes precision medicine as an approach that takes these individual differences into account rather than relying only on a one-size-fits-all model. Quick Answer: Precision medicine uses information about individual biological and environmental differences to help improve prevention, diagnosis and treatment. Genomics, genetic testing, biomarkers and pharmacogenomics are important parts of this rapidly developing field. What Is Precision Medicine? Precision medicine is an approach to healthcare that considers differences between indi...
