Multiple Choice
What is the primary function of a spliceosome in eukaryotic cells?
A
To remove introns from pre-mRNA
B
To add a 5' cap to mRNA
C
To synthesize ribosomal RNA
D
To transport mRNA out of the nucleus
Verified step by step guidance1
Understand the role of spliceosomes: Spliceosomes are complex molecular machines found in eukaryotic cells that are responsible for processing pre-mRNA.
Identify the components of pre-mRNA: Pre-mRNA contains both exons, which are coding sequences, and introns, which are non-coding sequences.
Learn the process of splicing: Splicing is the process by which spliceosomes remove introns from pre-mRNA, allowing the exons to be joined together to form mature mRNA.
Recognize the importance of splicing: The removal of introns is crucial for the correct translation of mRNA into proteins, as introns do not code for proteins and must be removed before translation.
Differentiate spliceosome function from other processes: While spliceosomes remove introns, other processes such as adding a 5' cap or synthesizing ribosomal RNA are carried out by different cellular machinery.
