Question

Quizplus · Accepted Answer

Introns are sequences of mRNA that are removed during the processing of the mRNA molecule. Exons, on the other hand, are sequences that remain in the final mRNA molecule and are ultimately translated into protein. Replicons refer to the DNA sequences that are replicated during cell division, promoters are DNA sequences that initiate transcription of a gene, and a gene is a segment of DNA that codes for a specific protein or RNA molecule.
