Theses and Dissertations
It has been widely reported that some genes are expressed at a higher level than others. However, it has not been shown whether each gene is expressed consistently between studies and at the same level compared to all other genes. Here, we examined six RNA-seq datasets and found that the mRNA level of each gene is indeed consistent relative to all other genes. This result implies that there are evolutionary pressures that drive genes to maintain either low or high expression. In order to identify these pressures, we compared gene expression level to the features of each gene (or associated …
