| | Please note that the definitions are often given to explain a word found in a particular context found in our text (Gilbert, Developmental Biology) and so may be somewhat narrowly or simply defined. | | | Dideoxynucleotides are used in molecular biology for Sanger-type DNA sequencing, and in medicine as anti-retroviral drugs for the treatment of HIV infection (e.g., ddI, ddC, and AZT). | | | Fusion of the acrosomal vesicle with the plasma membrane of the sperm (in the "acrosome reaction") exposes receptors that bind to the egg surface and is necessary for fertilization. |

| | The two types of metamorphosis typical of insect pests and natural enemies are gradual (egg > nymph > adult) and complete (egg > larva > pupa > adult). | | | The more we know about their biology and behavior, including their natural enemies, the more likely we will be able to manage them effectively. | | | For the reader who is unfamiliar with the biology or ecology of insects, this primer will provide needed background information. |

| | Organisms show two kinds of change through time: during the lifetime of a single animal (you don’t look much like the egg you started as) and during the evolutionary history of a biological lineage (you don’t look much like your three-and-a-half-billion-year-old ancestor). | | | The idea that embryology, as developmental biology was then known, reveals important truths about evolution also played a big part in the first real revolution in evolutionary thought: Darwinism. | | | And the Modern Synthesis, the second defining moment in the history of evolutionary biology, came close: it’s hard to think of evolution in the same way once you know that it has to obey the laws of Mendel’s genetics. |

| | Butterflies and moths undergo complete metamorphosis, in which there are four distinct stages: egg, larva (caterpillar), pupa, and adult. | | | The development of a butterfly or moth from egg to adult can take anywhere from three weeks to several years. | | | Hormones circulating within the body trigger the changes that occur during metamorphosis. |

| | Metamorphosis (biology) - Wikipedia, the free encyclopedia |
| | Some insects hatch from the egg, already having the general form of the adult, and the metamorphosis to adult form is usually marked mainly by the development of wings. | | | Metamorphosis is a process in biology by which an individual physically develops after birth or hatching, and involves significant change in form as well as growth and differentiation. | | | It usually accompanies a change of habitat or of habits, but may occur without such change. |

| | Early cell divisions of the fertilized egg, establishment of head-to-tail polarity, and the genetic circuit for body segmentation have all been modified, apparently as adaptations to the parasitic life-style. | | | 2) The body of a vertebrate animal is formed by a series of repeated blocks called segments, which include structures such as vertebrae, muscles and peripheral nerves. | | | The segmentation clock drives the periodic transcription in the presomitic mesoderm of so-called "cyclic genes", most of which are related to the Notch signalling pathway. |
