Which of the Following is a Constituent of the Phage

Question

Which of the following is a constituent of the phage l repressor?
A) DNA-binding domain
B) Dimerization domain
C) Connector region
D) DNA-binding domain and Dimerization domain
E) All of these are correct.

Accepted Answer

The phage lambda repressor, a protein crucial for the regulation of the phage lambda life cycle, comprises several functional domains including a DNA-binding domain, a dimerization domain, and a connector region. These components are essential for its ability to bind to DNA and regulate gene expression, as well as for the formation of dimers that are necessary for its function.
