What is an anticodon? Function, RNA Base Pairing

What is an anticodon? Anticodons are sequences of nucleotides that complement the codon. They are found in tRNA and allow tRNAs to produce the correct amino acids corresponding to mRNA during protein production. During protein production, amino acids are bound together in a string, such as beads on a necklace. The right amino acid must … Read more

What is antioxidant?Function, Benefits, and Examples

What is antioxidant? Antioxidants are molecules that prevent the oxidation of other molecules. Oxidation is a chemical reaction in which electrons are lost. In living things, this process can be harmful, causing a breakdown of organic molecules. One challenge of life on Earth is that oxygen makes it a great electron acceptor, which makes chemical reactions … Read more

Auxin Definition, function, Structure and Synthetic Auxin Analogs

Auxin Definition Auxin is a plant hormone derived from the amino acid tryptophan. An auxin may be one of several molecules, but all auxin molecules are involved in some type of cellular regulation. Auxin molecules are one of the five major types of plant hormones. Other major groups are gibberellin, cytokinin, ethylene, and abscisic acid. … Read more

Chitin Definition, Examples, Function, and Structure

Chitin Definition Chitin is a large, structural polysaccharide composed of chains of modified glucose. Chitin is found in the exoskeleton of pests, the fungal cell wall and invertebrates, and some hard structures in fish. In terms of abundance, chitin is second only to cellulose. In the biosphere, more than 1 billion tons of chitin are … Read more

Definition of centrioles, Function, Structure

Definition of centrioles Eukaryotic cells contain two rod-shaped, microtubular, cylindrical structures, called centrioles, near the nucleus. They lack a limiting membrane and no DNA or RNA and are found in most algae cells (a notable exception being red algae), moss cells, some fern cells, and most animal cells. They are absent in prokaryotic plants, red … Read more

Fatty Acids, Role, Types ,Unsaturated And Saturated

What is Fatty acids? Fatty acids are made up of hydrocarbon chains that end with carboxylic acid groups. Fatty acids and their associated derivatives are the main components of lipids. The length and degree of saturation of the hydrocarbon chain are highly variable between each fatty acid and dictates the associated physical properties (eg, melting … Read more

Animal cell definition, Diagram, Function, Organelles, Parts

Animal cell definition, Diagram, Function, Organelles, Parts What is an animal cell? Animal cells are the basic unit of life in organisms in the Animalia kingdom. They are eukaryotic cells, which means they have a true nucleus and specialized structures called organelles that carry out different functions. Animal cells do not have plant-specific organelles like … Read more

Mitochondria definition, Function, Structure

Mitochondria Definition Mitochondria are structures specific to the cells of animals, plants, and fungi. They act as batteries, powering the various functions of the cell and the organism as a whole. Although mitochondria are an integral part of the cell, evidence suggests that they evolved from primitive bacteria. What are mitochondria? Numerous small, spherical, club-shaped, … Read more

Cytoplasm Definition, Properties, Function, and Structure

Cytoplasm Definition, Properties, Function, and structure What is cytoplasm? The cytoplasm contains all the contents outside the nucleus and is enclosed within the cell membrane of a cell. It is clear in color and has a gel-like appearance. The cytoplasm is mainly composed of water but includes enzymes, salts, organelles, and various organic molecules. Properties … Read more

Platelets count, Low Platelet, High Platelet, Function

Platelets Count Platelets are only about 20% of the diameter of red blood cells. The normal platelet count is 150,000-350,000 per microliter of blood, but since platelets are so small, they represent only a small fraction of the volume of blood. The main function of platelets is to prevent bleeding. Red blood cells are the most … Read more
