Answers 100% PASS
If neither copy of chromosome 14 in a B cell successfully produces a productive
rearrangement of the heavy chain: - CORRECT ANSWER-The B cell commits
suicide
If segments of the genes used to make antibodies are not linked in frame properly
during gene rearrangement: - CORRECT ANSWER-Translation ceases and a
useless protein fragment results
The element of the adaptive immune system that differentiates it from other parts
of our immune response is its ability to: - CORRECT ANSWER-Protect against
nearly any kind of invader
Put the following steps in BCR construction in the proper order, from beginning
to end: - CORRECT ANSWER-Gene rearrangement occurs for the light chain
Fifth step
Productive rearrangement of the heavy chain is tested during translation
Second step
,Gene rearrangement occurs for the heavy chain
First step
The light chain is tested for proper fit with the heavy chain
Seventh step
The heavy chain is transported to the B cell's plasma membrane
Third step
Productive rearrangement of the light chain is tested during translation
Sixth step
The B cell proliferates with only it's heavy chain
Fourth step
The primary way in the which an antibody differs from a BCR is: - CORRECT
ANSWER-A BCR contains anchored into the plasma membrane of a B cell

, Substances that are not BCRs but causes BCRs to crosslink when they bind to the
surface of a B cell are called [ Select ], and the type of B cell activation that results
is called [ Select ]. - CORRECT ANSWER-Answer 1: Mitogens
Answer 2: Polyclonal Activation
Crosslinking of BCRs is defined as: - CORRECT ANSWER-The clustering
together of BCRs bound to their cognate antigens near each other on the plasma
membrane
B cells can be activated in which of the following ways (check all that apply): -
CORRECT ANSWER-Polyclonal activation
T cell-independent
T cell-dependent
As a B cell matures, it can change from making IgM-class antibodies to making
IgE-class antibodies. The process by which this occurs is called: - CORRECT
ANSWER-Class switching
