详细了解必应搜索结果 此处组织和汇总搜索结果Cytogenetics is a branch of genetics that studies the structure, function, and behavior of chromosomes. It focuses on the DNA within the cell nucleus, which is condensed during cell division and forms chromosomes. Through the techniques that are used, it is possible to identify the presence of a tumor cell among 20 normal cells.2 来源

Cytogenetics is essentially a branch of genetics, but is also a part of cell biology/cytology (a subdivision of human anatomy), that is concerned with how the chromosomes relate to cell behaviour, particularly to their behaviour during mitosis and meiosis. Techniques used include karyotyping, analysis of G … 展开
