Question
- DNA sequences found in introns providea. amino acid sequence information.b. regulatory information.c. no known useful information.d. structure for the gene.e. alternative DNA splicing possibilities.
Solution
The correct answer is b. regulatory information and e. alternative DNA splicing possibilities.
Introns are non-coding sections of an RNA transcript, or the DNA encoding it, that are spliced out before the RNA molecule is translated into a protein. While they do not provide amino acid sequence information (option a), they do play a role in gene regulation (option b). They can also influence the way in which the RNA is spliced, leading to different proteins being produced from the same gene (option e). So, it's not correct to say that they provide no known useful information (option c). They do not provide the structure for the gene (option d), but they can influence how the gene functions.
