Explanation / Answer

30.Ans. Cysteine and Histidine

zinc fingers are the small structural motifs that stabilizes the protein structure. the various proteins those contains zinc fingers functions by interacting with DNA, RNA and proteins. for example the binding strength of transcriptional factors was due to the zinc finger structure. zinc finger domain is stabilized by bound zinc ion through interaction with two Cysteine and two Histidine residues.

31.Ans. Leucine

one of the class of DNA binding unit called bZip proteins, it contains long alpha-helices stabilized by amino acid Leucine.

32.Ans.Nucleosome,solenoid

Nucleosome is a structural unit of chromosomes, DNA wraps around a core histone and stabilizes the structure. core histone complex is composed of 2 molecules of each H2A,H2B,H3 and H4. solenoid is model of DNA packaging where packing of DNA as a 30nm fiber around the histone octamer.

33.Ans.activate

Catabolite activator protein act as transcriptional activator. it binds at the CAP binding site at the promoter upon binding it recruits the RNA polymerase at the promoter, then RNA polymerase activates transcription process of structural genes of lac operon. usually CAP binds with the cAMP and cAMP-CAP complex activates the transcription process

34.Operon

it is a unit of gene expression that allows controlled and coordinated expression of a set of proteins. operon consists of Promoter to which RNA polymerase binds, Operator site to which Repressor protein binds and inhibits transcription process in the absence of Inducer and Inducer which binds to Repressor and activate the transcription process of structural genes.
