DNA的短重复序列 or DNA的重复短序列

Scientifically speaking, in the text provided above regarding the STR profiling technique, the study subject is the sequence (序列) of the DNA, not the whole chain of deoxyribonucleic acid (DNA).

STR analysis: The method of DNA profiling used today is based on PCR and uses short tandem repeats (STR). This method uses highly polymorphic regions that have short repeated sequences of DNA.
http://en.wikipedia.org/wiki/DNA_profiling#STR_analysis

Therefore, the more accurate corresponding Chinese phrase should be:
DNA的短重复序列 or DNA的重复短序列
(Please note, the former expression is more commonly used).
Example sentence:

大多数法证DNA 分析的检验对象都是DNA 的短重复序列,也就是所谓的“短串联重复序列(short tandem repeats,缩写为STR)

结果发现,在9个称为“微卫星DNA”的重复短序列中,有4个拉长了,2个缩短了。

重复的短序列DNA

短串联重复序列(short tandem repeat,STR),也称微卫星DNA(microsatelite DNA),由于重复单位较简单,故又称简单重复序列(simple repeat sequence,SBS)
