Multicopy single-stranded DNA refers to genetic material that contains multiple copies of a single strand of DNA. Synonyms for this term may include repetitive DNA, repetitive sequences, tandem repeats, and satellite DNA. These synonyms refer to the same concept of multiple copies of a single DNA strand, often found in non-coding regions of the genome. These regions of DNA can play important roles in gene regulation and have been associated with diseases such as cancer and neurological disorders. Understanding the functions and implications of multicopy single-stranded DNA is an active area of research in genetics and molecular biology.
