C. elegans in Biology Research

Description

Caenorhabditis elegans is a microscopic roundworm that lives in soil and has become an important model organism in biology. Scientists have used it since the early 1970s because it has an invariant body plan, is easy to manipulate genetically, and is inexpensive to maintain.

This roundworm is stu...

秀丽隐杆线虫,也被科学家称为"线虫", 彻底改变了我们用遗传学研究来了解基因如何调控细胞活动的方法。 线虫的遗传背景简单,身体透明且易于培养的特性使其成为研究胚胎发育,神经元的功能,寿命,老化以及一些人类疾病分子机制的理想系统。

首先,让我们了解作为模式生物的线虫。秀丽隐杆线虫隶属于线形动物门。 线虫是多细胞生物体,体长约1毫米。线虫的体型为细长的圆柱体,无分割和附属物。 在整个生命周期中,线虫的身体均为透明。线虫可以是雌雄同体或雄性。 雌雄同体既能自体受精也能和雄性交配。

线虫主要生活在湿度和氧气恒定的土壤中。

在实验室中,他们可在长满了大肠杆菌的...
