DNA can not pass through the spider bite to Petter in the movie spider man. Why?

Question

i know that genetic materials can not pass through the spider'd bite.
but can you explain why??
tnx for helping

Answer 1

It's a COMIC BOOK.

Answer 2

Those things (malaria, other diseases) are viruses or amoebas or bacteria or little teeny parasites. Which, yes, have DNA of their own, but they infect individual cells and change the individual cell structures. Like, some of them burrow into white cells and catch a ride undetected by the body. Tricky! They attack cells (or tissues, whatever they like) and the "sickness" you get is usually the body's reaction to the cells--your immune system is trying to kill off the invaders. Or they kill your killer T-cells and then you get sick from stuff your immune system can't fight off (like with HIV. You don't technically get all that sick from AIDS, but rather, from secondary infections because your immune system sucks.)

Now, radioactive substances can change DNA a bunch. Usually for the worse, but I guess every now and then, radiation could do something helpful. Genetic therapy isn't to the point where you can inject rogue DNA and have it go in cells and then the cells just multiply like, wheee! Now we're part spider! You have to finesse it a little more than that, and a spider bite just doesn't pass along that kind of DNA.

Also, spiders are rarely hosts of nasty DNA parasitic stuff. That's usually more of a fly/tick thing--spider venom is nasty and some types can kill you, but you're much more likely to get nipped by a rotten little tick or flea or mosquito, something like that. I guess they sometimes pass on diseases, but it's not too common.

Answer 3

A spider's bite is not usually an "exchange", but an injection of venom into it's prey. Spiders may later return to extract nourishment from the prey, but I would have to suspect that the venom of a spider's bite, in the miniscule amounts being considered, probably destroys the DNA of whatever it bites.

Answer 4

Theoretically, DNA can pass through a spider bite.

Malaria, yellow fever, and a whole bunch of other diseases are passed to humans by the bite of various insects

Answer 5

In the comics it was becasue the spider was radio active, not becasue of a genetically altered spider. Sad when that seems more realistice than that piece of crap movie. That movie changed a lot of history, which is why I hate it.

Answer 6

Wrong.

DNA can pass through, but DNA cannot impart attributes to Parker's DNA. Messenger RNA is used.

Answer 7

Apart from it being sci-fi you mean?

DNA from another person or animal would be recognised as an invader and attacked, as it is a foreign protein.

Answer 8

Yes whatever you want to hear

Answer 9

science/magic. get a job!!!
