Alimitation of retrovirus-mediated gene transfer is that

The answer is Retroviruses integrate DNA randomly in the genome. While retroviruses integrate their DNA permanently in their host genome, hence a good tool for gene therapy, its risk of inserting DNA at an unintended location on target genome can cause insertional mutagenesis. This mutation can cause activation of oncogenes hence lead to tumor growth.

a motor homunculus represents a map of brain areas dedicated to motor processing for different anatomical divisions of the body.

homunculus represents the importance of various parts of your body as seen by your brain. as a result, they take up a lot of brain space. although the cortical homunculus is a curiosity, penfield's work in mapping the brain's relationship to the body was invaluable.

the correct answer is: d. the saltine and pretzel are made of flour, yeast, and baking soda, and salt. the pecan contains no flour but it does contain fats. the pecan is a nut that can be consumed as a healthy snack. first of all, pecans are a source of fat (monounsaturated fat), but they provide less fat than some other nuts. pecans are a rich source of dietary fiber, manganese magnesium, phosphorus, thiamin, vitamin e…
