Explore the intricacies of gene expression in 'Block 1 Gene Expression'. This quiz assesses understanding of chromatin remodeling, ubiquitination, operon function, and transcription rates, crucial for students and professionals in genetics and molecular biology.
An extracellular matrix glycoprotein
A lipid which is susceptible to lipase action
An enzyme which cleaves the beta-lactam ring
A protein complex called the proteosome
A protein which lacks any alpha helical structure
Rate this question:
It determines the half-life of functional proteins, after expression
It determines the rate of mRNA translation in the cytosol
It determines the rate that an mRNA traverses the nuclear pore
It determines the Km and Vmax of enzymes
It determines a protein's membrane affinity
Rate this question:
The insulin gene
The glucose transporter gene, GLUT4
The transferrin receptor gene
The dystrophin gene
The retinoblastoma gene
Rate this question:
The rate of transcription of the gene encoding protein X is only 10 % of that of normal subjects.
The protein degradation rate of this protein X is at a much faster rate in the patient.
The post-translational modifications to this protein occur only to the extent of 10 % of a normal subject.
The Ribosomal machinery of this individual is compromised and inefficient in translating the mRNA encoding protein X
The blood test is very likely to be in error.
Rate this question:
It is called the sterol-receptor binding protein (SRBP)
It is one of several general transcription factors
It binds DNA by intercalation between DNA bases
It recognizes DNA in the enhancer region
It causes RNA polymerase I binding to the promoter region
Rate this question:
High tryptophan, low glucose
High tryptophan, high glucose
Low tryptophan, glucose doesn’t matter
Low tryptophan, high glucose
Low tryptophan, low glucose
Rate this question:
The CRP protein binds to the CAP site
The repressor binds to tryptophan in is released from its binding to the operator
The activator binds and facilitates RNA polymerase binding to the promoter
The attenuation of translation is relieved by the slower processivity of RNA polymerase
The amount of trp repressor protein is decreased by regulation of its own transcription
