A patient with a lymphoma has an involved lymph node resected and examined pathologically. The lymph node shows a malignant proliferation of small cleaved cells that are most prominent in the areas immediately outside the follicles.

This type of lymphoma is associated with a characteristic translocation that involves which of the following?
(A) bcl-1 and immunoglobulin heavy-chain gene
(B) bcl-2 and immunoglobulin heavy-chain gene
(C) c-abl and bcr
(D) c-myc and immunoglobulin heavy-chain gene
(E) PML and RAR-alpha(A) bcl-1 and immunoglobulin heavy-chain gene
(B) bcl-2 and immunoglobulin heavy-chain gene
(C) c-abl and bcr
(D) c-myc and immunoglobulin heavy-chain gene
