Four TAFs do have some intrinsic DNA binding ability: TAF4b, TAF12, TAF9, and TAF6 are (distant) homologs of histones H2A, H2B, H3, and H4, respectively.  TAF4b/TAF12 and TAF9/TAF6 form heterodimers using the histone fold motif

Examples of adapters. 


An adapter used to create BamHI sticky ends at the blunt ends of a DNA insert. 


A conversion adapter produced by associating two oligonucleotides, each having a different recognition sequence at its 5'~end but a complementary sequence for base pairing at the 3 '-end.

Adapters are short, chemically synthesized DNA double strands, which already have one or both sticky ends.

 A gel mobility shift assay detects interaction between a protein and DNA by the reduction of the electrophoretic mobility of a small DNA that occurs on binding to a protein.

A gel mobility shift assay, is a method for detecting DNA–protein interaction relies on the fact that a small DNA has a much higher mobility in gel electrophoresis than the same DNA does when it is bound to a protein.

Lane 3 depicts the behavior of the same DNA bound to two proteins. The mobility is reduced still further because of the greater mass of protein clinging to the DNA. This is 

called a supershift.

You want to study the potential interaction between nucleosome-bound DNA and a specific histone deacetylase. You decide to perform an electrophoretic mobility shift assay (EMSA).
