凝胶电泳技术在亲子签定、公安侦破案件、生物亲缘关系远近、DNA指纹技术等各方面运用已经非常普遍.只要提供血迹、毛发、骨骼碎片、精斑等组织或分泌物,就能通过凝胶电泳技术,用一种探针寻找DNA的不同部位并形成独特的条码进行基因比对,从而达到DNA签定的目的.电泳技术与分子的物理性质有关,如分子量或分子大小、形状、等电点等.高考命题注重能力考查,强调新情境与能力立意相结合,往往起点高,落点低,重在考查学生对情境信息获取和处理,进一步考查
Gel electrophoresis technology is very common in all aspects of parent-child sign-off, public security detection of cases, biological kinship, DNA fingerprinting, etc. As long as blood, hair, bone fragments, semen and other tissues or secretions are provided, Gel electrophoresis technology, using a probe to find different parts of DNA and form a unique bar code for gene alignment, so as to achieve the purpose of DNA sign.Electrophoresis technology and molecular physical properties, such as molecular weight or molecular size, shape, etc. Electricity point, etc. The college entrance examination proposition pays attention to the examination of ability, emphasizes the combination of new situation and ability conception, often starts from high point, low point, focuses on students to obtain and deal with context information, further examination
