Final answer:
After transcription, mRNA undergoes post-transcriptional modification and then travels to the cytoplasm. There, ribosomes translate the mRNA sequence into a protein, which is a key step in gene expression and protein synthesis.
Step-by-step explanation:
After mRNA is transcribed from the DNA, it undergoes several processes to carry out its role in protein synthesis. Initially, the mRNA is synthesized during the process of transcription. It then undergoes post-transcriptional modification in the nucleus, where it may be edited and spliced to form a mature mRNA molecule. Once the mRNA is processed, it exits the nucleus and enters the cytoplasm, where it interacts with ribosomes. The ribosomes 'read' the sequence of the mRNA and, with the help of tRNA molecules, translate it into a specific protein. This flow of information from DNA to RNA (transcription) and then to protein (translation) ensures that proteins are produced as needed for various cellular functions, following the central dogma of molecular biology.
