7 Questions
What is the primary function of miRNAs in gene regulation?
Modulating transcription of target messenger RNAs
Which type of organisms possess a well-conserved mechanism of gene regulation involving miRNAs?
Only eukaryotes
What is the average length of miRNAs?
22 nucleotides
What is the estimated number of miRNA genes encoded in the human genome?
6000
What is the function of the enzyme Dicer in miRNA processing?
To trim pri-miRNA into smaller segments
What is the function of RNA-induced silencing complex (RISC)?
To associate with mature miRNA
What is the consequence of miRNA regulation on protein expression?
It has a profound influence on protein expression
Test your knowledge on miRNAs, which do not encode proteins but modulate the translation of target mRNAs. Explore the fundamental mechanism of posttranscriptional gene regulation by miRNAs present in all eukaryotes. Learn how miRNAs influence protein expression and discover the machinery used by organisms to protect against foreign DNA.
