染色体是生物遗传物质基因的载体,是当前研究生物遗传的物质基础。开展染色体的研究,关键是方法。近10多年来,制备人类染色体的方法进展很快。这不仅加深了人们对染色体的认识,而且推动了医学的发展。目前,人类染色体的技术已广泛应用于临床医学的各个方面。通过染色体检查能为某些疾病的病 Chromosomes are the carrier of genes of biological genetic material and are the material basis of current research biological genetics. To carry out the study of chromosomes, the key is the method. For nearly 10 years, the preparation of human chromosomes has progressed rapidly. This not only deepens people’s understanding of chromosomes, but also promotes the development of medicine. At present, the technology of human chromosome has been widely used in all aspects of clinical medicine. Through the chromosomal examination for some diseases of the disease
