Which of the following observations supports the notion that the gene is simply a set of DNA
sequences that are transcribed into a single RNA molecule that encodes a single polypeptide?
(CSLO 1, CSLO 3, CSLO 4) Alternative splicing-a single gene can yield multiple mRNA and
protein products. A single ribosomal RNA transeript can liberate several RNA molecules via further
processing RNAs can be the functional product of a gene without being translated into a protein
product. Within a protein-coding region, each codon represents a specific amino acid that will be
linked to form a polypeptide. Regulatory elements are part of a gene that regulate timing, degree,
and specificity of gene expression but are not transcribed.
