What drives the formation of a liposome in an aqueous solution?

Hydrophobic effect and water release

What would be the immediate consequence of using a drug that inhibits chromatin remodeling proteins?

Inhibition of transcription initiation

Which statement correctly explains the entropy increase during micelle formation?

Water molecules are released, increasing system entropy

Entropy decreases due to lipid clustering

Micelles require ATP, which increases entropy

Entropy change is irrelevant to micelle formation

What is the primary function of clathrin in vesicular transport?

Forming a coated pit that shapes the vesicle

Hydrolyzing lipids for vesicle fusion

Mediating fusion with lysosomes

Phosphorylating vesicle membrane proteins

Which of the following best describes how epigenetic drugs can alter gene expression?

By modifying chromatin structure and DNA accessibility

What is the role of general transcription factors in eukaryotic gene expression?

They assist RNA polymerase in promoter recognition and initiation

They degrade mRNA after translation

They stabilize ribosomal subunits

They cleave DNA for exon removal

Why are cis-unsaturated fatty acids more fluid at room temperature than saturated fatty acids?

The cis-kinks prevent tight packing

They have longer hydrocarbon chains

They form stronger hydrogen bonds

They carry more negative charges

Which feature distinguishes eukaryotic promoter regions from prokaryotic ones?

Requirement for multiple general transcription factors

Use of sigma factors for RNA polymerase guidance

High sequence conservation across all genes

Continuous transcription of operons

What would be the effect of a mutation in a specificity factor that decreases its binding affinity for RNA polymerase?

Decreased transcription at target promoters

Enhanced transcription of housekeeping genes

Increased chromatin condensation

Stabilization of mRNA transcripts

If a drug inhibits topoisomerase I, which of the following would likely occur?

Accumulation of torsional strain during replication

Degradation of histone proteins

Activation of RNA interference pathways

What is the role of scramblase in lipid bilayers?

Non-selectively redistributes lipids across both leaflets

Selectively flips phospholipids to the inner leaflet

Removes damaged lipids from the membrane

Inserts cholesterol into lipid rafts

Which of the following best describes the solubility trend of fatty acids in water?

Solubility increases with double bond number and decreases with chain length

Solubility increases with chain length and saturation

Solubility is independent of structure

Saturated fatty acids are always more soluble than unsaturated ones

What structural characteristic allows glycerol to serve as a key molecule in lipid biochemistry?

Its prochiral nature enabling stereospecific reactions

Which three types of proteins are essential to initiate transcription?

RNA polymerase, transcription factors, chromatin remodelers

Helicase, topoisomerase, ligase

What drives the formation of micelles in an aqueous environment despite the apparent decrease in entropy from lipid aggregation?

Release of water molecules surrounding hydrophilic heads

Activation of phospholipase enzymes

Binding of cholesterol to tails
