Which of the following is an example of post-transcriptional control of gene expression?

Post-transcriptional controls of gene expression __________.

What is the evolutionary significance of alternative RNA splicing?

What determines how long a particular mRNA molecule will persist in a eukaryotic cell?

Although the number of genes in the human genome is surprisingly low compared to less complex organisms, the number of possible products from those genes is greatly amplified by __________.

Which of the following best describes the current understanding of the makeup of the human genome?

The discovery of many noncoding RNAs is causing scientists to revise the long-held view that __________.

MicroRNAs and small interfering RNAs both function similarly in "silencing" genes. What are two ways in which they may act?

It is hypothesized that an increase in the number and diversity of noncoding RNA (ncRNA) in the genomes of species has driven the evolution of morphological complexity by way of their influence on gene regulation. Which of the following accurately represents our current understanding of the role that ncRNA is thought to play in gene regulation?

What is alternative splicing?a. phosphorylation that leads to different types of post-translational regulationb. mRNA processing that leads to different combinations of exons being spliced togetherc. folding that leads to proteins with alternative conformationsd. the outcome of regulatory proteins that leads to changes in the life span of an mRNA
