Wasserman 655 solutions What is removed from RNA after transcription?In splicing, some sections of the RNA transcript (introns) are removed, and the remaining sections (exons) are stuck back together. Some genes can be alternatively spliced, leading to the production of different mature mRNA molecules from the same initial transcript.
What is the name of the process of going from a strand of mRNA to a protein?After the transcription of DNA to mRNA is complete, translation — or the reading of these mRNAs to make proteins — begins. Recall that mRNA molecules are single stranded, and the order of their bases — A, U, C, and G — is complementary to that in specific portions of the cell's DNA.
What is removed from an mRNA Strand before it is complete?At this point, at least in eukaryotes, the newly synthesized mRNA undergoes a process in which noncoding nucleotide sequences, called introns, are clipped out of the mRNA strand. This process "tidies up" the molecule and removes nucleotides that are not involved in protein production (Figure 6).
What has been removed from the prePre-mRNA is made from the template strand of DNA starting at the promoter by the transcription initation complex (RNA polymerase and transcription factors). When the RNA polymerase reaches the terminator, the pre-mRNA is released. Introns are removed and the methyl cap and poly-A tail are added to make mRNA.
