20 Questions
Which type of RNA can encode for more than one protein in prokaryotes?
mRNA
What is the role of tRNA in protein synthesis?
Carrying individual amino acids to ribosomes
Which enzyme is responsible for RNA synthesis?
RNA polymerase
What is the function of small nuclear RNAs (snRNAs)?
Splice RNA
What is the primary role of RNA polymerase in the elongation phase of RNA synthesis?
Reading DNA template and generating mRNA
How does a-amanitin affect RNA polymerase type 2?
It inhibits mRNA precursors and snRNA production
What is the impact of Rifampicin on bacterial transcription?
It inhibits the initiation phase of transcription
Which viral genomes require RNA-directed RNA polymerase for replication?
RNA-based genomes
What is the structure formed through complementary base pairing within the same RNA molecule?
Stem
Why is RNA less stable than DNA?
RNA has a single-stranded structure, making it more susceptible to cellular damage.
What type of RNA possesses enzymatic activity and can cleave either themselves or other RNA molecules?
Ribozyme
Which type of RNA acts as a template for protein synthesis?
mRNA
What is the sequence of bases in RNA responsible for providing coding information?
Nucleotide sequence
What forms when there is no complementary base pairing and bulges form due to mismatches in RNA?
Hairpin loop
Which type of RNA can take the form of monocistronic where one RNA encodes for one protein?
mRNA
Polymerase chain reaction (PCR) is used to amplify RNA molecules for sequencing.
False
Ribosomal RNA (rRNA) is only found in eukaryotic cells.
False
RNA polymerase reads the DNA sequence from 5' to 3' direction during RNA synthesis.
False
Small nuclear RNAs (snRNAs) are involved in the synthesis of ribosomal RNA.
False
Rifampicin inhibits the elongation phase of RNA synthesis.
True
Test your knowledge on the structure of RNA molecules and their ability to form secondary structures through complementary base pairing. Learn about the constant sugar-phosphate backbone, varying bases, nucleotide composition, coding information, single-stranded nature, and the formation of different secondary structures like stems and bulges.
