Beginning within the nucleus, the first step leading to the synthesis of a polypeptide is beginning within the nucleus, the first step leading to the synthesis of a polypeptide is transferring of information from dna to messenger rna translation of an rna nucleotide sequence into a sequence of amino acids translation of a dna nucleotide sequence into a sequence of amino acids removal of introns from rna and the stitching together on exons linking of nucleotides to form a polypeptide

The dna in a cell’s nucleus encodes proteins that are eventually targeted to every membrane and compartment in the cell, as well as proteins that are targeted for secretion from the cell. for example, consider these two proteins: phosphofructokinase (pfk) is an enzyme that functions in the cytoplasm during glycolysis. insulin, a protein that regulates blood sugar levels, is secreted from specialized pancreatic cells. assume that you can track the cellular locations of these two proteins from the time that translation is complete until the proteins reach their final destinations.for each protein, identify its targeting pathway: the sequence of cellular locations in which the protein is found from when translation is complete until it reaches its final (functional) destination. (note that if an organelle is listed in a pathway, the location implied is inside the organelle, not in the membrane that surrounds the organelle.)

Were you able to observe the nucleolus in any of the cells if so which ones

If a checkpoint detects damaged dna, the checkpoint may
