The Exon Encoding the V Region of an Immunoglobulin Protein

Multiple Choice

The exon encoding the V region of an immunoglobulin protein is generated by a process of somatic recombination. This recombination event brings V gene and J gene segments together:

A) In all cells of the body to encode a V region sequence
B) To generate maximum diversity in the CDR3 sequence of the V region
C) By alternative RNA splicing to encode a V region sequence
D) By a precise mechanism that never adds or loses nucleotides at the junction
E) To generate a single exon encoding the entire immunoglobulin protein
