Are algal genes in nonphotosynthetic protists evidence of historical plastid endosymbioses?
(East Carolina University, 2009)
Background: How photosynthetic organelles, or plastids, were acquired by diverse eukaryotes is among the most hotly debated topics in broad scale eukaryotic evolution. The history of plastid endosymbioses commonly is ...
Functional Unit of the RNA Polymerase II C-Terminal Domain Lies within Heptapeptide PairsÂ
(East Carolina University, 2004-06)
Unlike all other RNA polymerases, the largest subunit (RPB1) of eukaryotic DNA-dependent RNA polymerase II (RNAP II) has a C-terminal domain (CTD) comprising tandemly repeated heptapeptides with the consensus sequence ...
