Introduction TP53, more commonly known as the Tumor Suppressor Gene is what protects a gene from over developing into cancerous cell. TP53 is responsible for regulating nuclear processes within the chromosome ultimately maintaining the cell's cycle and making sure it stays on its correct course, even assisting in apoptosis. The TP53 gene sends signals to make a protein called tumor protein p53 (or p53). This protein is the tumor suppressor itself, it regulates cell division by keeping cells from
of Biblical creation directly calls into question the Bible=s authority on its moral teachings. As Ken Ham, from the WGBH Boston Video Evolution Series: What About God? states, AYwhat it [the Bible] says is what it meansYit relates to the authority of scripture and the gospelsYso, if the Bible got it wrong in astronomyYgeologyYbiologyYthen why should I trust the Bible when it talks about morality and salvation? [i]@ It is no wonder with sentiments like these that the backlash against evolution
the N-terminal part of the amino acid sequence [26]. Nuclease is one of the acknowledged proteins secreted by members of the genus Lactobacillus. After several evidences of extracellular DNAse activity, nucleases from several Lactobacillus species have been identified by two methods; sodium dodecyl sulfate polyacrylamide gel electrophoresis, coupled to in-gel protein renaturalization and nuclease assay [28]. It has been shown that nuclease activity over the DNA present in the luminal content, can
Understanding Huntington's Disease Huntington's disease is an inherited neurodegenerative disorder. It is passed on to children from one or both parents (though two parents with Huntington's is extraordinarily rare) in an autosomal dominant manner. This is different from autosomal recessive disorder, which requires two altered genes (one from each parent) to inherit the disorder. So if one parent has it, and passes the gene on to a child, that child will develop Huntington's disease if they live
