ABC model of flower development guided by three groups of homeotic genes. The ABC model of flower development is a scientific model of the process by which flowering plants produce a pattern of gene expression in meristems that leads to the appearance of an organ oriented towards sexual reproduction , a flower.
One class is involved in the protein (e.g. toxins, hydrolytic enzymes, S-layer proteins, lantibiotics, bacteriocins, and competence factors) export and the other in drug efflux. ABC transporters have gained extensive attention because they contribute to the resistance of cells to antibiotics and anticancer agents by pumping drugs out of the cells.
This list contains a list of sub-classes for the seventh group of Enzyme Commission numbers, EC 7, translocases, placed in numerical order as determined by the Nomenclature Committee of the International Union of Biochemistry and Molecular Biology.
The Binas is divided into five chapters: general, physics, mathematics, chemistry, and biology. Each chapter consists of multiple tables, each with specific information. These tables can be short or can span up to a few pages. To find information, students can use the alphabetical register in the back.
The following outline is provided as an overview of and topical guide to zoology: . Zoology – study of animals.Zoology, or "animal biology", is the branch of biology that relates to the animal kingdom, including the identification, structure, embryology, evolution, classification, habits, and distribution of all animals, both living and extinct, and how they interact with their ecosystems.
Superman is a plant gene in Arabidopsis thaliana, that plays a role in controlling the boundary between stamen and carpel development in a flower. [1] It is named for the comic book character Superman, and the related genes kryptonite (gene) and clark kent were named accordingly (although, appropriately, the latter turned out to just be another form of superman). [2]
Tinbergen's four questions, named after 20th century biologist Nikolaas Tinbergen, are complementary categories of explanations for animal behaviour.These are also commonly referred to as levels of analysis. [1]
The P-type ATPases, also known as E 1-E 2 ATPases, are a large group of evolutionarily related ion and lipid pumps that are found in bacteria, archaea, and eukaryotes. [1] P-type ATPases are α-helical bundle primary transporters named based upon their ability to catalyze auto- (or self-) phosphorylation (hence P) of a key conserved aspartate residue within the pump and their energy source ...
