Suppose that nucleic acid hybridization experiments revealed that the mRNA-DNA complexes form different loop patterns depending on which cell type is the source of the mRNA.Such data would support
A) the one-gene, one-polypeptide hypothesis.
B) the conclusion that the genetic code is redundant but not ambiguous.
C) the conclusion that the genetic code is ambiguous but not redundant.
D) the existence of alternative splicing.
E) the conclusion that the genetic code is not universal.

Question

Quizplus · Accepted Answer

The formation of different loop patterns in mRNA-DNA complexes suggests the existence of alternative splicing, where different combinations of exons and introns can be spliced together to produce different variants of mRNA from the same pre-mRNA. This is supported by the fact that different cell types may require different sets of proteins to carry out their specific functions, and alternative splicing allows for greater diversity in the types of proteins that can be produced from a single gene. The other choices do not directly relate to the observation of different loop patterns in mRNA-DNA complexes.
