The Impact of Repetitive Elements in the Genome

Repetitive elements are sequences of DNA that are scattered across the genome, often in either interspersed or tandem array. These elements can be either genetic material or proteins, which can influence gene expression, regulation, and other processes such as recombination (Gurzov, 2019). A tandem array is a type of arrangement where repeated elements are found in a consecutive, uninterrupted fashion (Meyer et al., 2017). For example, some tandem arrays can be found in the human genome, such as the long terminal repeat (LTR) retrotransposons. LTR retrotransposons are a type of mobile genetic element that can move around the genome, replicating and inserting themselves into new locations (Liu et al., 2020). On the other hand, interspersed repetitive elements are scattered throughout the genome and are not placed in a consecutive, uninterrupted fashion (Kumar et al., 2021). An example of such an element is the short interspersed nuclear element (SINE) which is a type of non-autonomous, mobile genetic element that often replicates and inserts itself into new locations in the genome (Kim et al., 2016).
