MicroRNAs and Gene Expression Regulation Quiz

Alternative RNA splicing (correct)

RNA processing

Initiation of translation

Post-translational modification

Small double-stranded RNA molecules that can regulate gene expression by binding to complementary sequences on DNA molecules in the nucleus and triggering their breakdown or blocking transcription

Small single-stranded DNA molecules that can regulate gene expression by binding to complementary sequences on DNA molecules in the nucleus and triggering their breakdown or blocking transcription

Small double-stranded RNA molecules that can regulate gene expression by binding to complementary sequences on mRNA molecules in the cytoplasm and triggering their breakdown or blocking translation (correct)

Small single-stranded DNA molecules that can regulate gene expression by binding to complementary sequences on mRNA molecules in the cytoplasm and triggering their breakdown or blocking translation

Slides with thousands of different kinds of single-stranded DNA fragments attached in a tightly spaced array, allowing researchers to determine which genes are switched on or off in a particular cell by comparing patterns of gene expression (correct)

Slides with thousands of different kinds of double-stranded RNA fragments attached in a loosely spaced array, allowing researchers to determine which genes are switched on or off in a particular cell by comparing patterns of gene expression
