11. Beskrive DNA bindingsområder for proteiner og hvordan proteiner genkender disse bindingsområder

The protein binding regions of DNA are called transcription factor binding element. As their name suggest, they serve as binding sites for proteins that control the transcription. They are usually no longer then 10 nucleotides.  

The protein recognizes the binding sequence of the DNA by forming non-covalent bonds. This usually occurs in the major groove, because the base pairs that project into this groove are more accessible for scanning and binding.
