Dyad repeats
In genetics, dyad symmetry refers to two areas of a DNA strand whose base pair sequences are inverted repeats of each other. They are often described as palindromes. For example, the following shows dyad symmetry between sequences GAATAC and GTATTC which are reverse complements of each other. See more Since the two reverse complementary sequences will fold and base-pair with each other, the sequence of bases between them form a hairpin loop. This structure is thought to destabilize the binding of See more Temperate bacteriophages integrate into the host genome at specific interrupted dyad symmetry sequences using the phage encoded enzyme integrase (see prophage integration See more • Definition at Biology Online See more WebTypical direct repeats (DR SCC -R and DR SCC -L), as well as hitherto unreported dyad repeats (DyadR-R and DyadR-L) present at both right and left extremities of the chromosome-SCC mec...

About 1 kbp upstream of DS, an array of tandem repeats 650 bps in total size, termed the “family of repeats” (FR), provides 20 sequence motifs to which EBNA1 molecules bind with high affinity.
