Questions: 15 | Attempts: 12 | Last updated: Mar 20, 2026

Sample Question
What is RNA interference, and what was the key experimental observation that first demonstrated this phenomenon?

RNA interference is a process in which single-stranded antisense RNA binds directly to ribosomes and blocks translation by sterically preventing ribosomal movement along the mRNA

RNA interference is the degradation of double-stranded RNA by cytoplasmic nucleases as part of the innate immune response, first observed when cells were infected with double-stranded RNA viruses

RNA interference was discovered when Fire and Mello injected double-stranded RNA into Caenorhabditis elegans and observed potent, sequence-specific silencing of the corresponding gene, far more effective than either sense or antisense RNA alone, revealing an endogenous cellular pathway for gene silencing

RNA interference is a nuclear process in which RNA polymerase II produces antisense transcripts that base-pair with nascent pre-mRNAs and trigger their degradation before nuclear export

Questions: 15 | Attempts: 12 | Last updated: Mar 20, 2026

Sample Question
What is the fundamental principle of semiconservative DNA replication, and what experimental evidence first confirmed it?

DNA replication is conservative, meaning both new strands are synthesized entirely from free nucleotides while the original double helix is preserved intact as a reference template

DNA replication is dispersive, meaning original and new DNA are randomly interspersed throughout all daughter molecules following each round of replication

Each newly replicated DNA molecule consists of one original parental strand and one newly synthesized complementary strand, confirmed by the Meselson-Stahl experiment using nitrogen isotope density labeling

DNA replication produces two entirely new double helices from nucleotide precursors while the original parental strands are degraded to recycle their nucleotides for new synthesis

A noncovalent hydrogen bond that forms between complementary nitrogenous bases on opposite strands of the double helix

A bond between a deoxyribose sugar and a nitrogenous base that anchors each nucleotide within the helical structure

A covalent bond formed between the phosphate group of one nucleotide and the 3-prime hydroxyl group of the adjacent nucleotide's sugar, creating the continuous backbone of each DNA strand

A weak electrostatic interaction between the negatively charged phosphate groups on adjacent nucleotides that maintains strand polarity
