Which of the following mechanism is responsible for Multiple proteins from a single gene?: (A) RNA interference, (B) mRNA capping, (C) Mutations in the promoter of the gene, (D) Alternate Splicing
Answer is D. Alternate patterns of hnRNA splicing result in different mRNA molecules which can produce different proteins. Alternate splicing results in mRNA heterogeneity in fact, the processing of hnRNA molecules becomes a site for the regulation of gene expression.
