What is Cytosol? | Definition of cytosol Cytosol can be defined as the cytosol is the fluid inside the cells. It is the water-based solution in which organelles, proteins, and other cellular structures float. The cytosol in any cell is a complex solution, whose properties allow the functions of life to take place. The cytosol … Read more
What is bilirubin? Bilirubin is a molecule formed by the breakdown of red blood cells and other cells with porphyrins. Red blood cells carry special molecules, called hemes (a type of porphyrin), that house an iron atom. This arrangement allows red blood cells to carry oxygen. When blood cells break down, they release heme into … Read more
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 a Phenotype? A Phenotype is the physical expression of DNA. Rather, a genotype is the chemical composition of DNA that causes a particular phenotype. DNA is first transferred to RNA, which is a separate information molecule, which can then be translated into protein. Phenotypes are caused by interactions of many different proteins produced by DNA. … Read more
What is an adaptation? An adaptation, or adaptive trait, is a trait produced by DNA or an indigenous’s interaction with the environment. While not all adaptations are entirely positive, for an adaptation to persist in a population it must increase fitness or reproductive success. All children, whether sexually or asexually, inherit their qualities from their … Read more
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
Definition of cytokinesis Cytokinesis is the final process in eukaryotic cell division, which divides the cytoplasm, organelle, and cellular membrane. Cytokinesis after telophase usually occurs at the end of mitosis, but there are two independent processes. In most animals, cytokinesis begins in late anaphase or early telophase, to ensure that the chromosomes are completely separated. … Read more
Gene Definition A gene is a highly specific sequence of nucleotide monomers that can fully or partially regulate the expression of one or more traits in every type of living organism. Genes are formed from deoxyribonucleic acid (DNA) and in the case of some viruses, ribonucleic acid (RNA) polymers. Overview|Gene Definition It was Wilhelm Johansen … Read more
Coenzyme Definition A coenzyme is a non-protein organic compound that binds with an enzyme to catalyze a reaction. Coenzymes are often widely called cofactors, but they are chemically different. A coenzyme cannot work on its own, but it can be reused multiple times when combined with an enzyme. Coenzyme functions An enzyme without a coenzyme is called apoenzyme. … Read more
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
