Suppose you made the intestinal sac too small, and at the end of experiment you could collect only 100 microliters of solution instead of 200 microliters for analysis. You perform the DNS reaction with 100 ul of the recovered solution and 100 ul of water (to bring volume up to 200 ul). How that would affect the concentration of glucose you determined from the standard curve?

Normal Experiment
200 ul solution
200 ul of DNS
400 ul of H2O

A)Half the true concentration
B)Twice the true concentration
C)Equal to the true concentration

Proteins are the workhorses of the cell, controlling virtually every reaction within as well as providing structure and serving as signals to other cells. proteins are long chains of  amino acids  , and the exact sequence of the amino acids determines the final structure and function of the protein. instructions for that sequence are encoded in  genes  . to make a particular protein, a messenger ribonucleic acid (mrna) copy is made from the gene (in the process called  transcription  ), and the mrna is transported to the  ribosome  . protein synthesis, also called  translation  , begins when the two ribosomal subunits link onto the mrna. this step, called initiation, is followed by elongation, in which successive amino acids are added to the growing chain, brought in by transfer rnas (trnas). in this step, the ribosome reads the  nucleotides  of mrna three by three, in units called  codons  , and matches each to three nucleotides on the trna, called the anticodon. finally, during termination, the ribosome unbinds from the mrna, and the  amino acid  chain goes on to be processed and folded to make the final, functional protein
