Cloning the Progesterone 5 beta- reductase gene
... We soon found that the Butterfly we chose (the Monarch) does not actually produce the toxin itself but rather sequesters it from its food source, the Milkweed, as a larvae and pupa. The milkweed itself did not have a gene on file that we could isolate so we did some research on what exactly this tox ...

DNA: The molecular basis of mutations
... 1. No change occurs in phenotype. Some mutations don't have any noticeable effect on the phenotype of an organism. This can happen in many situations: perhaps the mutation occurs in a stretch of DNA with no function, or perhaps the mutation occurs in a protein-coding region, but ends up not affectin ...

It is exactly the same as DNA except for one thing; instead of the nitrogenous base thymine, all RNA has the nitrogenous base uracil (U). • The newly created mRNA then leaves the nucleu ...
