Describe the process of translation as it would occur for a protein that is secreted into the lumen of the endoplasmic reticulum. Include the role of signal peptides, SRP's, SRP receptors, and pores. Actin can have several roles in the cell. Replication units are activated at different times during chromosomal replication. Describe how cilia move.
B cells are lymphocytes that, when stimulated, become antibody-secreting plasma cells.
One of the changes that occurs is that B cells initially have a membrane-bound form of antibody, which later turn into a secreted form. The two forms are exactly alike, except for their amino terminal end. This portion of the exam consists of multiple choice questions, true false questions, and five short discussion questions worth 5 pts each. One of the short discussion questions is extra credit. Multiple choice have only one correct answer.
