A zinc finger DNA binding domain is
A) the promoter for a zinc-containing enzyme.
B) a DNA sequence which interacts with zinc to enhance the action of trans-acting control proteins which regulate gene transcription.
C) a double stranded region of DNA which is activated by zinc.
D) a DNA sequence which binds regulatory proteins found in eukaryotes.
E) a helix-loop-helix structure in the linear DNA.

Question

Quizplus · Accepted Answer

Zinc finger DNA binding domains are structural motifs in proteins, not sequences in DNA. They enable proteins to bind to DNA, playing crucial roles in various biological processes, including gene expression and regulation. These proteins are found in eukaryotes and are involved in the regulation of gene transcription by binding to specific DNA sequences.
