Final answer:
After transcription, DNA undergoes post-transcriptional modifications and control mechanisms before it is translated into a protein.
Step-by-step explanation:
After transcription, the DNA molecule undergoes post-transcriptional modifications before it is translated into a protein. These modifications include the processing of the mRNA molecule, such as the removal of introns and the addition of a cap and a poly-A tail. Additionally, post-transcriptional control mechanisms, such as RNA splicing and regulation of RNA stability, contribute to the regulation of gene expression at the level of mRNA.
