In some genes the protein-coding sections of the DNA ("exons") are interrupted by non-coding regions ("introns"). RNA splicing removes the introns from pre mRNA to produce the final set of instructions for the protein.
Transcript: As DNA is transcribed into RNA it needs to be edited to remove non-coding regions, or introns, shown in green. This editing process is called splicing, which involves removing the introns, leaving only the yellow, protein-coding regions, called exons. RNA splicing begins with assembly of helper proteins at the intron/exon borders. This process is repeated for every intron in the RNA. No known hominin is common ancestor of Neanderthals and modern humans, study suggests -- ScienceDaily. The search for a common ancestor linking modern humans with the Neanderthals who lived in Europe thousands of years ago has been a compelling subject for research. But a new study suggests the quest isn't nearly complete. The researchers, using quantitative methods focused on the shape of dental fossils, find that none of the usual suspects fits the expected profile of an ancestor of Neanderthals and modern humans. They also present evidence that the lines that led to Neanderthals and modern humans diverged nearly 1 million years ago, much earlier than studies based on molecular evidence have suggested.
The study, which will be published online this week by the Proceedings of the National Academy of Sciences, was carried out by an international team of scholars from The George Washington University, Konrad Lorenz Institute for Evolution and Cognition Research in Austria, Indiana University and Atapuerca Research Team in Spain. P. What comes next? Making a Genealogy Map Using the Google Maps API. Introduction I wanted to try out using the Google Maps API for a project, so I decided I’d try to use it in conjunction with some genealogy data to see what I could come up with.
The result is a family tree which is mapped out spatially rather than chronologically; once rendered, the following visual data is revealed: Migration paths - see where particular people suddenly moved a large distance Geographical density/immobility - see which areas the most family members were from Most popular places - see which villages or cities successive generations lived in Example Click on the image below to view a live example of the project (using real data from my family tree) and then read on for an explanation of how the program works: Features Google Maps features: Pan and zoom around the map using AJAX technology Switch to vector mapping, satellite mapping or hybrid maps Program features: By way of compromise, it is possible to adjust the zoom level via a variable at the top of the program though.
