Repeated sequences (also known as repetitive elements, repeating units or repeats) are short or long patterns that occur in multiple copies throughout the genome. In many organisms, a significant fraction of the genomic DNA is repetitive, with over two-thirds of the sequence consisting of repetitive elements in humans. [1]

2023年9月19日 · Repetitive DNA sequences playing critical roles in driving evolution, inducing variation, and regulating gene expression. In this review, we summarized the definition,...

Repetitive DNA is defined as a specific sequence of nucleotides that is repeated, sometimes many times, within our genetic material. The repeated sequence in question can be short, with a pattern consisting of only a few nucleotides, or long—more than 50 nucleotides.

Repetitive DNA is a DNA segment with a specific DNA sequence that is repeated multiple times in the genome. Moderately repetitive DNA refers to 10–105 copies of the sequence per genome. Moderate repeated DNA is found primarily in noncoding sequences.

Here, we review the surprising abundance of repetitive DNA in many genomes, describe its structural diversity, and discuss dozens of cases where the functional importance of repetitive elements has been studied in molecular detail.

2025年3月12日 · Repetitive DNA refers to sequences of DNA that are repeated multiple times throughout the genome. These sequences can range from a few base pairs to several thousand base pairs in length. Repetitive DNA sequences are a significant component of the genome, especially in eukaryotes, where they can constitute a large portion of the DNA.

2021年3月29日 · Through the power of genomic sequencing, it is now well established that large components of the genomes of humans and many other organisms are composed of repetitive DNA elements. The nature of...

Repetitive DNA Sequences refer to DNA sequences that are often involved in transcriptional silencing by attracting specific DNA-binding proteins, leading to the formation of heterochromatin. This silencing can occur at various types of repeats, such as centromeric tandem repeats and dispersed repeats like transposable elements and integrated ...

Repetitive DNAs include both short and long sequences that repeat in tandem or are interspersed throughout the genome, such as transposable elements (TE), ribosomal rRNA genes (rDNA), and satellite DNA. Repetitive DNA is ubiquitous in eukaryotic genomes, but despite this universality, their possible functions and predictable patterns of ...

Repetitive DNA--sequence motifs repeated hundreds or thousands of times in the genome--makes up the major proportion of all the nuclear DNA in most eukaryotic genomes.
