What is Mendel’s Law of Independent Assortment? Definition of Mendel’s Law of Independent Assortment Mendel’s Law of Independent Assortment states that genes for different traits are distributed to gametes independently of one another, meaning the inheritance of one trait does not affect the inheritance of another. Characteristics of Mendel’s Law of Independent Assortment Examples of … Read more
What is Mendel’s Law of Dominance? Mendel’s Law of Dominance is one of the foundational principles of genetics, formulated by Gregor Mendel through his experiments with pea plants. It asserts that when two homozygous organisms, each possessing contrasting traits for a specific character, are crossed, only one of the traits will appear in the first … Read more
In the 1860s, Gregor Mendel, an Austrian monk, revolutionized the field of genetics with his foundational work on inheritance patterns. His experiments with pea plants led to the development of Mendelian inheritance, which is based on the concept that heredity operates through discrete units called genes. These genes, according to Mendel, act independently within an … Read more
What is Mendelian Inheritance/Mendel’s Laws of Inheritance? Genetics Terminology of Mendelian inheritance These terms clarify how genes operate, how traits are inherited, and the relationship between genetic information and observable characteristics. Download the Cheat sheet pdf Mendel’s Experiment Gregor Mendel’s experiments between 1856 and 1863 laid the foundation for our understanding of genetic inheritance. Using … Read more
What are Prions? Definition of Prion A prion is an infectious, misfolded protein that causes neurodegenerative diseases by inducing abnormal folding of normal cellular proteins, leading to the accumulation of these misfolded proteins in the brain. Unlike other infectious agents, prions lack nucleic acids and propagate their abnormal structure through direct protein-protein interactions. Characteristics of … Read more
Animal cell are considered to be the fundamental living species belonging to the kingdom Animalia. They are eukaryotic cells which means they possess an actual nucleus as well as organelles, which are special structures which perform various functions. Animal cells don’t have specific organelles for plants, such as cell walls that support the plant cell or the chloroplasts, an organelle that is responsible for photosynthesis.
What is Mycorrhiza? Definition of Mycorrhiza Mycorrhiza refers to the symbiotic association between specific fungi and plant roots, where the fungus aids in nutrient and water uptake for the plant, and in return, the plant provides the fungus with essential nutrients produced through photosynthesis. Types of Mycorrhizae Mycorrhizae represent diverse symbiotic associations between fungi and … Read more
An electron microscope is a type of microscope that uses a beam of electrons to create an image of a sample. Electron microscopes have a higher resolution than optical microscopes, which use light to form an image, and can be used to observe objects that are too small to be seen with an optical microscope. … Read more
Domain: Bacteria Phylum: “Firmicutes” Class: Bacilli Order: Bacillales Family: Bacillaceae Genus: Bacillus Species: B. cereus Definition of Bacillus cereus Bacillus cereus is a gram-positive, rod-shaped bacterium that produces toxins leading to foodborne illnesses. It can cause two main types of gastrointestinal disorders: emetic (vomiting) syndrome and diarrheal syndrome. This bacterium is commonly found in soil … Read more
Microvilli are tiny, finger-like projections found on the surface of epithelial cells throughout the body, particularly in the small intestine. These structures significantly increase the surface area of the cells, enhancing their ability to absorb nutrients and other substances. The primary functions of microvilli include facilitating nutrient absorption, aiding in the process of fertilization, supporting … Read more
