Which Event Does Not Occur During Formation of the Heavy

question 53

Multiple Choice

Which event does not occur during formation of the heavy chain of an antibody?

• A) Assembly of supergenes by splicing of individual genes of the heavy chains is coordinated with that of light chains.
• B) Before transcription, a variable region supergene is formed through DNA rearrangement in which one each of the variable genes (V), diversity genes (D), and joining genes (J) are joined together.
• C) Following RNA splicing, mRNA is translated to produce a polypeptide chain.
• D) After transcription, RNA splicing removes introns and joins the variable region to the constant region.
• E) Mutations occur due to imprecise recombination of selected DNA regions.
