大蒜根尖有丝分裂染色体标本的制作

染色体是遗传物质的载体,是基因的载体.生物体细胞的染色体数目和结构是重要的遗传标志之一,特别是在真核细胞中.因此深入认识染色体的结构和功能,对研究生物的遗传、变异、进化、细胞增殖、个体的发育和生殖过程的平衡控制都有十分重要意义.本实验以大蒜根尖为材料,介绍了大蒜根尖细胞有丝分裂标本的制作方法.该方法简单、方便,材料易得,成功率高,适用于对正常植物组织有丝分裂过程的观察.

Carlic Root Tip Contain the Manufacture Research of the Silk Abruption Chromosome Specimen

Chromosome is the carrier of genetic material. Organisms cell chromosome number and structure are important genetic markers, especially in eukaryotic cells. Thus it is very meaningful that the structure and function of biological study of genetic variation, evolution, cell proliferation are understanded Individual development and the balance of the reproductive process control is very meaningful. In this experiment, garlic root of the material on the garlic apical cell mitosis specimen preparation methods. The method is simple, convenient and easy to get materials, a high success rate that applies to the normal plant tissue mitotic process of observation.
