the student is crying for her biology test with only a frosting covered donut for lunch specialized cells in her pancreas respond to the increasing amount sugar in her blood by releasing insulin a small protein that regulates blood sugar levels let's go inside one of these cells to see how this protein is manufactured instructions for making insulin are coded by a segment of DNA in the nucleus in transcription and enzyme Zips along the DNA forming RNA shown here in red RNA nucleotides line up with their complementary DNA Partners transcribing the information in DNA into RNA as the RNA grows it is cast in several ways first a modified guanine nucleotide is added to the beginning as a cab also segments of the RNA strand that do not actually code for the protein are removed and the remaining side YouTube RNA are we connected finally extra adenine nucleotides are added to the end of the RNA strand forming a tail the completed messenger RNA mRNA leaves the nucleus the message in mRNA is translated into a protein in the cytoplasm first a transfer RNA TRNA arrives carrying a specific amino acid the small subunit of a ribosome attaches to the MRNA now the largest subunit of the ribosome attaches a second TRNA docks bringing another amino acid to the ribosome helps to form a covalent bond between the two amino acids Cameron a shift and the first TRNA leaves a new TRNA brings another amino acid to the ribosome helps to form a new Bond and the process is repeated notice that one end of a TRNA molecule has a set of three bases called an anticodon the pairs with complementary bases on the MRNA the other end of the TRNA carries specific amino acid different types of TRNA scary different amino acids in this way the message in mRNA is translated into a specific sequence of amino acids the proteins that will be secreted from the cell like insulin the ribosome doc's on the rough ER and the protein grows into the ER compartment the new protein molecules are packaged in a vesicle that is transported to the Golgi apparatus where many proteins are processed however insulin is packaged in a vesicle that leaves the Golgi and is then processed secreted from the cell are shipped to the plasma membrane cheer insulin is secreted from the pancreas and begins to regulate the students rising blood sugar levels
