Question

Which of the following statements about RNA splicing is FALSE?

-it removes the introns
-it is performed by the spliceosome
-it shortens the RNA molecule
-it always occurs in the nucleus
-all of these choices are true

Answer 1

RNA splicing removes introns and joins exons together in a precise manner, while not shortening the RNA molecule.

Step-by-step explanation:

The statement that is FALSE about RNA splicing is "it shortens the RNA molecule".

RNA splicing is a process that removes introns, non-coding sections, from pre-mRNA and joins the protein-coding exons together. This is done by spliceosomes, complexes of proteins and RNA molecules, in a precise and sequence-specific manner.

RNA splicing always occurs in the nucleus and is essential for ensuring the correct reading frame and the production of functional proteins.
