found the gene period Genes are like blue prints.Proteins (蛋白质) are the chemicals those blueprints make to do the work of genes.The gene period made a protein called PER.It turned out that PER's role was to turn off its own production.That means it works like a feedback (反馈) ...
The rest of the organelles in the cytoplasm, then, ultimately derive from genes, as does the spatial organization of the egg that helps set off development. This is not to say that random factors, like chemical concentration in...
HER2, in particular, is currently recognized as an oncogenic driver and has been proven to be one of the causative genes of breast cancer. The poor prognosis of breast cancer is associated with HER2/neu protein overexpression due to HER2/neu gene amplification, which is similar to colon cancer...
our genes hold the blueprints for proteins. When a particular gene is expressed, the protein whose code the gene carries will be made within the cell expressing it. The differences between various types of cells in
DNAconsists of many genes and is itself organized into structures known aschromosomes,of which humans have 23 pairs. A fruit fly has four pairs of chromosomes, while a dog has 39 pairs. The genetic code in the genes and DNA tell the body how to makeproteins. Proteins are extremely importan...
Follow the lecture closely and look for opportunities to ask relevant questions.
volcanic activity can turn a livable world into a molten nightmare. But too little activity can shut down the release of gases that make up an atmosphere, leaving a cold, barren surface. Just the right amount supports a livable, wet planet like Earth, or a possibly livable moon like Europa...
This should not be surprising; genes have to do all their own work of spreading. There's no Evolution Fairy who can watch the gene pool and say, "Hm, that gene seems to be spreading rapidly—I should distribute it to everyone." In a human market economy, someone who is legitimately ge...
Professor Carlos Caldas, lead author and Cancer Research UK scientist based at the University of Cambridge, said: "The METABRIC study mapped out the genetic blueprints for breast cancer. And these new results give us even more detail about which genetic faults could be linked to how different ty...
Bicknell's thrush. Credit: Steve Faccio Bicknell's Thrush has been identified as a globally vulnerable Nearctic-Neotropical migratory bird in need of serious conservation efforts. This species travels each year between its breeding grounds in the Canadian maritime provinces and upper northeastern United...
