Q. about lambda repressor bind. site

[taylor]

Hi

	I had a couple of questions about the bacteriophage lambda 
repressor binding site:

1)  The DNA sequence for which the repressor has the highest affinity

2)  Is the affinity increased by the presence of 2 repressor binding
sites in tandem, and if so, the ideal distance in bp between the two
tandem sites.

Any suggestions or refrence leads will be appreciated.

Thanks in advance

Prem
