What are microsatellite DNA sequences also known as?

Microsatellite DNA sequences are best known as Short Tandem Repeats (STRs). These are repeating sequences of 1-6 base pairs of DNA that are distributed throughout the genome. Their short repeating nature allows them to be highly polymorphic, meaning they can vary greatly among individuals in a population, making them useful for genetic studies, including forensic analysis and paternity testing.

In contrast, Long Interspersed Elements are much longer repeating sequences found in the genome and are classified as a type of transposable element. Single Nucleotide Polymorphisms (SNPs) refer to variations at a single base pair in the DNA sequence, which are different from the multi-unit repeats characteristic of microsatellites. Gene Variations encompasses a broader concept that includes various types of genetic differences, but does not specifically refer to the short, repeating nature of microsatellites. Thus, identifying microsatellite DNA as Short Tandem Repeats is precise and reflects their structural characteristics and significance in genetic diversity studies.
