DOUBLE MINUTE Meaning and
Definition
-
Double minute is a term commonly used in the field of genetics and molecular biology. It refers to a specific phenomenon that occurs in cells when an excessive copy number of certain portions of DNA, known as "minute chromosomes," is present.
In ordinary circumstances, cells possess two copies of each chromosome, one inherited from each parent. However, in the case of double minute, there are extra copies of small chromosomal fragments that are not organized into specific chromosomes. These fragments, often circular or linear, contain specific genetic material that can vary in size. Double minutes are typically considered to be an aberration in chromosomal structure, resulting from errors during DNA replication or from the amplification of specific genes.
Double minutes can be observed using various laboratory techniques, such as fluorescence in situ hybridization (FISH) or karyotyping. Their presence can indicate genetic instability or abnormality, and they have been associated with various cellular processes, such as cancer development and drug resistance. In cancer research, double minutes are of particular interest due to their potential role in amplifying oncogenes, which are genes that promote the growth of cancer cells.
Overall, "double minute" refers to the extra copies of small fragments of DNA that are not part of regular chromosomes, and their presence can have important implications in understanding genetic abnormalities and disease progression.
