The insulin protein in humans helps control how much sugar is in our bloodstream. Diabetics do not correctly produce insulin and millions of diabetics must take insulin. Today, the human insulin protein can be mass-produced through a genetic engineering process using recombinant DNA. This insulin is biosynthesized by genetically manipulating certain bacteria, like E. coli. Commercially available recombinant DNA human insulin identical to pancreatic human insulin.
How can you explain the similarity of the two insulin proteins?
A) There are a variety of amino acid sequences for both the bacterial and human insulin protein.
B) Both the amino acid sequence and the transcription and translation of that code is identical in both organisms.
C) Scientists cut and paste to transcribe the correct nucleotide sequence in E. coli, as if it were being transcribed naturally in humans.
D) While the nucleotide sequences may vary in each organism, the process of translation reorders the nucleotides into the correct order of the insulin protein.

Which is an advantage of having memory cells when a pathogen is encountered for a second time. a) the memory cells are what proliferate into clones of cells in response to the binding of an antigen. b) memory cells are vital to the primary immune response in that they immediately recognize pathogens even at the first encounter. c) memory cells are essentially effector cells that are short lived and attack antigens even without having a receptor specific to that antigen. d) it ensures that more lymphocytes with a receptor specific to a particular antigen will be present than in a host that had never encountered that pathogen.
