quadruplicated

Quadruplicated refers to something that has been repeated or multiplied by four. This term can be applied in various contexts. In genetics, a quadruplicated gene means an organism has four copies of a particular gene instead of the usual one or two. This can lead to altered gene expression and potentially phenotypic changes. In mathematics, quadruplication can refer to the act of multiplying a number by four, or a set containing four identical elements. For instance, a quadruplicated sequence might be a list of numbers where each number appears four times in a row. In a more general sense, it can describe any situation where four identical or very similar items are present. For example, one might speak of quadruplicated records if four identical copies of a document exist. The concept emphasizes the presence of fourfold repetition or multiplication.
