non-coding DNA

It may be similar to other kinds of non-coding DNA which have a regulatory role.

When the differences in non-coding DNA are taken into account, that difference rises to 4 or 5 percent.

Initially, a large proportion of non-coding DNA had no known biological function.

They are generally non-coding DNA but sometimes are part of possible genes.

The amount of non-coding DNA varies greatly among species.

(The actual percentage of non-coding DNA is not known with accuracy.

The role for many of these highly conserved non-coding DNA sequences is not understood.

Novel genes can also arise from previously non-coding DNA.

This observation was deemed counterintuitive before the discovery of non-coding DNA.

In such circumstances then, "genome" describes all of the genes and information on non-coding DNA that have the potential to be present.

However, recent research suggests that many mutations in non-coding DNA do have slight deleterious effects.

The remaining 95% is known as dark genome or non-coding DNA and its function is still unknown.

Many commercial ventures are concentrating on the ‘gene-rich’ regions of the human genome, ignoring the non-coding DNA.

The coding regions of the gene are separated by non-coding DNA which is not involved in protein expression.

There has been a steady stream of press releases that act as if finding a function for non-coding DNA is a complete surprise.

Many microsatellites are located in non-coding DNA and are biologically silent.

What effects, or perhaps even functions, does this non-coding DNA have for chromosomes, nuclei, cells, and organisms?

Regulatory, junk, and non-coding DNA are all partly overlapping categories, which helps foster confusion.

He points out that even so called non-coding DNA has a function, i.e. contains codes, although different from the triplet code.

Important non-coding DNA sequences that are essential for regulating gene expression will show differential selective pressure.

Also called non-coding DNA.

From where does this non-coding DNA come, and how is it spread and/or lost from genomes over time?

When there is much non-coding DNA, a large proportion appears to have no biological function for the organism, as theoretically predicted in the 1960s.

Discovered the functionality of Microsatellites (simple sequence repeats) among non-coding DNA.

Enhancers are non-coding DNA sequences, containing several binding sites for a variety of transcription factors.
