Final answer:
The statement that an intron is a section of RNA that gets spliced out is true. Introns are noncoding sequences removed from pre-mRNA during processing in eukaryotic cells to produce functionally correct proteins.
Step-by-step explanation:
True, an intron is a section of RNA that gets spliced out. In eukaryotic cells, the RNA transcript, also known as pre-mRNA, often contains regions called introns. These introns are noncoding sequences that are transcribed into RNA but are not translated into protein.
The splicing process involves the removal of introns from the pre-mRNA, which occurs while the RNA is still within the nucleus. After splicing, only the exons, which are the coding regions, remain and are then joined together to form the mature mRNA. This mature mRNA leaves the nucleus and is translated into proteins by the ribosome in the cytoplasm.
