Tanscription/translation - Start and stop codons

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.

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

HSPA1B, also known as A2007, belongs to a family of proteins called the heat shock proteins, or stress proteins; HSPA1B is expressed in response to heat shock and a variety of other stress stimuli, including oxidative free radicals and toxic metal ions.
