Regulation of gene expression

Question 1

Helix turn helix

Answer 1

Two alpha helices connected by short stretch of amino acids that form attend between two hills is common in prokaryotic DNA binding proteins

Question 2

Zinc finger

Answer 2

Alpha helix and two pleated sheets held together with a zinc atom common and eukaryotic DNA binding proteins that regulate transcription
Bayern’s two major groove of the DNA and zinc is used to stabilize the fold of the protein

Question 3

Leucine

Answer 3

Two alpha helices cross over each other these Hellas is held together by the hydrophobic interactions between our groups in amino acid leucine common in eukaryotic DNA binding proteins that regulate transcription

Question 4

Regulatory proteins

Answer 4

Binds to DNA then move along it and scan for the sequence they are looking for without having to unwind and open the helix they bind as diamonds

Question 5

Helix loop helix

Answer 5

Two alpha helixes connected by a loop 1 longer than the other one he looks falls and packs against another Hilux because the flexibility of the loop the structure that binds to an additional helix-loop-helix motive another protein if the two helix-loop-helix proteins are the same a homodimer is formed if there different heterodimer
