Which one of the following is wrong? RNA splicing.
A) is responsible for the joining of V, D, and J segments in formation of a heavy chain immunoglobulin protein.
B) is sometimes an autocatalytic reaction which can occur without added proteins.
C) is often mediated by particles called spliceosomes containing both RNAs and proteins.
D) occurs in the nucleus to form a complete, translatable mRNA with a single open reading frame.
E) often results in the excision of the intron as a structure known as a lariat.

Question

Quizplus · Accepted Answer

RNA splicing is a process primarily involved in the removal of introns and joining of exons in pre-mRNA to form mature mRNA. The joining of V, D, and J segments in the formation of a heavy chain immunoglobulin protein is a process known as V(D)J recombination, which is distinct from RNA splicing and involves the rearrangement of genetic material at the DNA level, not RNA.
