2.  Also called intergenic regions, Any of the
DNA in between gene-coding DNA,
including untranslated regions, 5' and 3'
flanking regions, INTRONS, non-functional
pseudogenes, and non-functional
repetitive sequences. This DNA may or
may not encode regulatory functions
 Introns: is any nucelotide sequence
within a gene that is removed by RNA
splicing which generate the final mature
RNA product of a gene

3.  The gaps or spaces between the genes
that lie on chromosomes termed intergenic
regions. By definition, intergenic regions are
non-coding, (i.e., they are not transcribed
into codons) and therefore do not direct
the protein synthesis via messenger
RNA(mRNA). Although not transcribed,
intergenic regions have been shown to play
a role in the expression of adjacent genes
and there is increasing evidence that they
contain important control sequences.

4.  Recent research suggests, however, that
intergenic regions between genes may
play critical roles in the process of
imprinting, cancers and some birth
defects. Current research projects are
attempting to more accurately
characterize the intergenic regions near
imprinted genes that cause the
expression of one parental allele over
another

5.  Molecular biologist use sophisticated
mathematical techniques and modeling
enhanced with modern computer
technology (e.g. bioinformatic analysis) to
identify intergenic nucleotide sequences
and to investigate their potential role
in cell regulation. Sophisticated computer
algorithms may lead to a more detailed
understanding of the role intergenic regions
may play in gene regulation.
