How does RNA differ from DNA in terms of stability?
RNA is generally less stable than DNA.
RNA is more stable than DNA
RNA is only stable under certain conditions.
RNA and DNA have the same stability.
Which of the following best describes the role of transfer RNA (tRNA) during protein synthesis?
tRNA constructs ribosomes from amino acids.
tRNA carries genetic information from DNA to mRNA.
tRNA synthesizes proteins directly.
tRNA brings amino acids to the ribosome and pairs with mRNA.
What is the primary function of ribosomal RNA (rRNA) in protein synthesis?
To carry amino acids to the ribosome
To stabilize the mRNA during translation
To transfer genetic information from DNA to mRNA
To construct the ribosome and facilitate protein synthesis
In the process of transcription, what role does RNA play in relation to DNA?
RNA replaces DNA in the nucleus.
RNA replicates DNA for cell division.
RNA carries the instructions from DNA to synthesize proteins
RNA stabilizes the DNA structure.
