Concept explainers
To explain:
The reason STRs may be used for identification.
Given:
Human genomic short tandem repeats (STRs) are specific gene sequences containing base pairs that are repeatedly arranged.
Introduction:
The human genome is full of repeated DNA sequences. These repeated sequences come in various sizes and are classified according to the length of the core repeat units, the number of contiguous repeat units, and/or the overall length of the repeat region. DNA regions with short repeat are named Short Tandem Repeats (STR). STRs are found surrounding the chromosomal centromere. STRs have proven to have several benefits that make them especially suitable for human identification.

Nitrogen, a mineral, is an important part of all living cells. All organisms need nitrogen in order to grow and repair. Although nitrogen exists in its elemental form in the atmosphere, it cannot be directly used by plants. 7 Where else can plants obtain their nitrogen from? Plants make their own nitrogen. B Plants get it from animals. Plants get it from the soil. D Plants have special structures to break down atmospheric nitrogen. v3.7.63.140.4 | 6763e9417a3dbb80fa0f87b2 | Dec 19, 2024 | 3:07 PM | 84126 | en_8arrow_forward
