Chromosome 17 is an example of a submetacentric chromosome, with its centromere located approximately in the center, but not exactly.
染色体17就是一个亚中着丝粒染色体的例子，其着丝粒位置大约位于中心但并不完全在正中间。
Submetacentric chromosomes have two distinct arms that are clearly unequal in length.
亚中着丝粒染色体具有两条明显长度不等的臂。
During cell division, the orientation of submetacentric chromosomes ensures proper segregation of genetic material.
在细胞分裂过程中，亚中着丝粒染色体的定向确保了遗传物质的正确分离。
In humans, chromosomes 1, 3, and 19 are classified as submetacentric due to their unique shape and position of the centromere.
在人类中，由于其独特的形状和着丝粒位置，1号、3号和19号染色体被归类为亚中着丝粒染色体。
The identification of submetacentric chromosomes plays a crucial role in karyotyping and diagnosing chromosomal abnormalities.
对亚中着丝粒染色体的识别在核型分析和诊断染色体异常方面起着至关重要的作用。
A majority of the human autosomes are either metacentric or submetacentric, contributing to the stability of the genome.
大多数人类常染色体要么是中着丝粒染色体，要么是亚中着丝粒染色体，这有助于基因组的稳定性。
Submetacentric chromosomes exhibit variation in size and gene content between their short and long arms.
