Question
Which description applies to RNA processing? O O O O O heritable changes in gene expression that occur without altering the DNA sequence a gene cluster controlled by a single promoter that transcribes to a single mRNA strand processing of exons in mRNA that results in a single gene coding for multiple proteins mRNA modifications such as additions of a 5' cap and 3' poly-A tail and removal of introns protein modifications such as addition of a functional group, or structural changes such as foldingExplanation / Answer
Heritable changes in gene expression that occur without altering the DNA sequence - Epigenetics
A gene cluster controlled by a single promoter that transcribes to a single mRNA strand - Operon
Processing of exons in mrna that results in a single gene coding for multiple proteins - Alternative mRNA splicing
mRNA modification such as additions of a 5’cap and 3’ poly –A tail and removal of introns - RNA processing
Protein modifications such as addition of a functional group, or structural changes such as folding - Post-translational gene regulation
