Question 1 of 5
Which of the following differentiates an antigen from an immunogen?
Correct Answer: C
Rationale: An antigen binds immune receptors but doesn't always provoke a response (unlike an immunogen), making c the key differentiator.
Question 2 of 5
Can transfer across the placental (maternal protection)
Correct Answer: A
Rationale: IgG crosses the placenta to provide maternal immunity to the fetus.
Question 3 of 5
Which of the following is used to enumerate and/or separate live cells that express an antigen, sorted by applying an electric charge to the stained cells?
Correct Answer: C
Rationale: FACS (fluorescence-activated cell sorting) uses fluorescence and electric charge to sort live cells based on antigen expression, unlike the other methods which do not involve cell sorting.
Question 4 of 5
Which of the following is only contained in heavy chains and not in light chains?
Correct Answer: C
Rationale: The Diversity (D) segment is unique to heavy chains, contributing to antibody diversity, and is not present in light chains.
Question 5 of 5
Production of secreted antibodies (pAs site) involves a chain of amino acids with a stretch of charged (versus non charged) amino acids at the terminus, in comparison to membrane bound antibody production (pAm site).
Correct Answer: B
Rationale: Secreted antibodies have a shorter, charged COOH terminus compared to the longer, hydrophobic terminus of membrane-bound antibodies.
