transcriptional attenuation

why is there transcriptional attenuation in cells? more specifically, why is there transcriptional attenuation in genes which are known to be oncogenic? for instance, if c-myc, is only required in a small amount, why was the gene made with so many fricken exons, and that transcriptional attenuation ...

basically asexual reproduction is cloning. the daughters are exactly the same as the mothers. that is not to say that evolution won't occur... it'll just be at a snails pace compared to the sexual reproducers. during the process of cell division, mutations can occur. these can be silent, detrimental...

personally, i don't think it's a good idea. taking just one compund, that has clinically been shown to reduce cancer, and placing only it in a totally different environment can cause problems. quite often, when this has been attempted, there is no therapeutic value whatsoever. a better option is to ...

Ok, have you tested out the primers first to see if they work? I mean, RT the RNA and then run a normal PCR (preferably on gradient) to see if you get the band size you want. do your primers go through an intron? have you tried different temps? have you tried different Mg++ concentrations? what conc...

can i play too? Meiosis is the process by which germ cells with 46 chromosomes develop into sperm or egg cells with 23 chromosomes. There is evidence that testicular germ cell tumors may form when something abnormal happens during meiosis. Instead of forming normal sperm cells with 23 chromosomes, a...

Fruits and vegetables reduce the risk of developing cancer in the human body. This is because they are high in anti-oxidents (reducing free radicals), and particularly for the digestive tract....they are high in fiber. It's generally thought that a diet high in fibre prevents cancer by not letting t...
