Tanscription/translation - Start and stop codons

Description:
The diagram represents a single strand of DNA containing a gene, in purple. Remember this gene is "read" in the 5' to 3' direction to produce an mRNA. To make a protein (polypeptide), mRNA is translated, or read, three nucleotides at a time. Each triplet codon specifies an amino acid to be added to the growing polypeptide chain. In addition to the amino acid designations, specific "start" and "stop" codons begin and end the protein sequence.

In most eukaryotic genes, coding regions (exons) are interrupted by noncoding regions (introns).
15550. Transcription/translation -PolyA-tails - the end
The majority of eukaryotic mRNAs contain a tract of A residues at the end. These polyA-tails are not encoded in the DNA. Rather, they are added to the pre-mRNA "post-transcriptionally" (after transcription). The end of pre-mRNA is cut by a specific enzyme
