Most of the DNA in our bodies is termed ‘junk DNA'. It is non-coding (isn't used for making proteins) and thus does not control medical function but is probably involved in genomic organization. Genetic genealogy only looks at the markers within junk DNA and thus the Y-DNA test cannot derive any medical information.
DNA that according to molecular biologists that has no value. Since most of the DNA of a particular organism does not code for proteins it was assumed the that remaining DNA had no value. This concept has been challenged recently with the discovery of non-random patterns that exist within this non-coding DNA.
The 97% of the human genome that is repetitive sequence and does not contain exons.
Portions of DNA that don't have genes with an obvious function.
DNA that does not have any apparent biological trait or function. It is possible that so-called "junk" DNA may have purposes that have not been determined.
Stretches of DNA that do not code for genes, also called non-coding DNA. Most of the genome consists of non-coding DNA, and was therefore long thought to be 'junk.' Scientists have found that in addition to containing markers that are helpful for genetic genealogy, parts of these non-coding regions have regulatory and other functions.
Stretches of DNA that do not code for genes; most of the genome consists of so-called junk DNA which may have regulatory and other functions. Also called non-coding DNA.
Areas of DNA that do not have an identified purpose, or do not code for genes.
A misleading term for about 97% of human DNA which does not yet have any known function.
uneeded DNA that is does not help code for anything.
Term used to describe the excess DNA that is present in the genome beyond that required to encode proteins. A misleading term since these regions are likely to be involved in gene regulation, and other as yet unidentified functions
DNA that codes for something, we just don't know what it is yet. Falsely believed to be vestigial by evolutionists.
a term used to describe the excess DNA which is present in the genome beyond that required to encode proteins. The term is misleading since these regions are likely to be involved in gene regulation, and other not yet known functions; a non-coding sequence of DNA; an intron
Slang term usually used in referring to the non-coding region of DNA on the Y-chromosome. For more about: http://www.psrast.org/junkdna.htm
In molecular biology, "junk" DNA is a collective label for the portions of the DNA sequence of a chromosome or a genome for which no function has yet been identified. About 97% of the human genome has been designated as "junk", including most sequences within introns and most intergenic DNA. While much of this sequence may be an evolutionary artifact that serves no present-day purpose, some is believed to function in ways that are not currently understood.
