Biological applications of bifurcation theory provide a framework for understanding the behavior of biological networks modeled as dynamical systems. In the context of a biological system, bifurcation theory describes how small changes in an input parameter can cause a bifurcation or qualitative change in the behavior of the system.
Oscillation (cell signaling) Oscillations are an important type of cell signaling characterized by the periodic change of the system in time. [1] Oscillations can take place in a biological system in a multitude of ways. Positive feedback loops, on their own or in combination with negative feedback are a common feature of oscillating biological ...
Phyletic gradualism is a model of evolution which theorizes that most speciation is slow, uniform and gradual. [1] When evolution occurs in this mode, it is usually by the steady transformation of a whole species into a new one (through a process called anagenesis ). In this view no clear line of demarcation exists between an ancestral species ...
Morphology (biology) Morphology in biology is the study of the form and structure of organisms and their specific structural features. [1] This includes aspects of the outward appearance (shape, structure, color, pattern, size), i.e. external morphology (or eidonomy ), as well as the form and structure of internal parts like bones and organs, i ...
Comparison of natural and synthetic selection processes for peptide generation. In biotechnology, combinatorial biology is the creation of a large number of compounds (usually proteins or peptides) through technologies such as phage display. Similar to combinatorial chemistry, compounds are produced by biosynthesis rather than organic chemistry.
Hoodwinked!is a 2005 American independentanimated mystery comedy film. It retells the folktale "Little Red Riding Hood" as a police procedural, using backstories to show multiple characters' points of view. It was produced independently by Blue Yonder Films with Kanbar Entertainment, directed and written by Cory Edwards(in his directorial debut ...
Anabolism ( / əˈnæbəlɪzəm /) is the set of metabolic pathways that construct macromolecules like DNA or RNA from smaller units. [1] [2] These reactions require energy, known also as an endergonic process. [3] Anabolism is the building-up aspect of metabolism, whereas catabolism is the breaking-down aspect. Anabolism is usually synonymous ...
Nucleic acid hybridization. In molecular biology, hybridization (or hybridisation) is a phenomenon in which single-stranded deoxyribonucleic acid ( DNA) or ribonucleic acid ( RNA) molecules anneal to complementary DNA or RNA. [1] Though a double-stranded DNA sequence is generally stable under physiological conditions, changing these conditions ...
