Document Summary

It causes an infection it has a flagella it is found in the human body all of the above are true. Somatic recombination is defined as changes in dna sequences that occur in non-germline cells. A ted can form a covalent bond with . Rods and cones are how humans detect light. Bacteria can be seen at 500-1000 nm. Viruses can be seen at 0. 5-15 nm but it is impossible to see. Resolving = being able to differentiate two different things. You use that equation when it is below a specific number and you cannot see. The limit of resolution is about half of the wavelength. The greatest resolving power is the shortest wavelength. If you want to view something smaller the tools you need are uv and x-ray. The shorter the wavelength the higher the energy. Melanin absorbs the uv light and and the more melanin the more the skin is protected.

1. The pre-B-cell receptor provides an important signal that induces transition of pro-B cells to pre-B cells. An important characteristic of this receptor is that:
A. It signals without binding to an extracellular ligand.
B. It is composed of immunoglobulin heavy chains and the VJ region of a rearranged gamma light chain.
C. It is expressed at very high levels on the surface of the pro-B cell.
D. It signals without requiring association with B-cell receptor signaling subunits, Igalpha and Igbeta

2. The vaccine to Haemophilus influenzae type b is called a conjugate vaccine. It is composed of the tetanus toxoid protein conjugated to the capsular polysaccharide of the H. influenzae type b bacteria. When used to vaccinate infants, the antibody response generated by this vaccine would include:
A. Antibodies to the bacterial polysaccharide and the tetanus toxoid
B. Antibodies to the tetanus toxoid only
C. Antibodies to the bacterial polysaccharide only
D. Antibodies that only bind to the protein-polysaccharide conjugate in the vaccine
E. Antibodies that recognize the polysaccharide capsule
when shed by the bacteria
E. It signals without requiring the B-cell receptor signaling kinase, BTK.

3. CXCR5 is the receptor for the chemokine CXCL13, secreted by follicular stromal cells and follicular dendritic cells in the B cell zones (i.e., lymphoid follicles) of secondary lymphoid organs. A conditional knockout mouse in which CXCR5 was specifically deleted only in T cells would have:
A. No defects in any type of antibody response
B. Defects in the initial activation of all B cells
C. A lack of discrete B cell and T cell zones in the
lymphoid organ
D. A defect in T cell-dependent antibody responses
E. An increased number and size of germinal centers
