Distribution of repetitive
within Exon / Intron structures
The 14 exons [numbered
for a single gene constitute a very small portion of the total
50 Kbp region. The introns [light-green areas] include a
number of families of repetitive
DNA sequences, shown in the exploded view below.
These include short
interspersed repeats (SINES,
including Alu family sequences), long interspersed repeats (LINEs,
including the L1 family), long tandem repeats (LTRs), and simple
sequence repeats (SSRs) (also known as micro- or minisatellites).
