Which of the following is used to generate diversity in the antibody repertoire? Select one: a. Presence of multiple variable gene segments that can be assembled in multiple different combinations b. Addition of N nucleotides that are not encoded in the germ line c. Exonuclease trimming of excess nucleotides at variable segment junctions d. Ability to pair a single heavy chain with different light chains, so as to avoid generation of autoreactive antibodies e. All of the above

3. antibody diversity is generated by multiple mechanisms, each of which contributes to the generation of antibodies with a multitude of different amino acid sequences in their antigen-binding sites. several of these mechanisms involve changes in the dna sequences encoding the antibody heavy and light chain proteins. one mechanism that does not rely on changes to the dna within the immunoglobulin heavy and light chain gene loci is, but is instead dependent on: a) the random usage of kappa light...

Part 1 out of 2 Your B-cells can produce millions of different types of immunoglobulins (antibodies) even though here are only about 200 genes encoding the different parts of an antibody. The light chains of an antibody are assembled by joining a variable segment, a joining segment, and a constant segment from a single immunoglobulin gene. Gene rearrangement within an immunoglobulin gene brings together one of forty different variable segments with one of four different joining segments, and the single...

QUESTION 1: You are inserting a gene into an MCS found within the LacZ gene. Using blue/white colony selection, why could you assume that white colonies have modified plasmids? a. A blue colony means the LacZ reading-frame was disrupted b. A blue colony means your gene has mutations c. A white colony means the LacZ reading-frame is intact d. A white colony means the LacZ reading-frame was disrupted QUESTION 2: You are performing a PCR using primers with a sequence perfectly...

2. According to the paper, what is the major disadvantage of
relying on glycolysis during high-intensity exercise? (5

3. Using Figure 1 in the paper, briefly describe the different
sources of ATP production at 50% versus 90% AND explain whether you
believe this depiction of ATP production applies to a Type IIX
