Did DNA come from space? (science homework)?

DNA cannot come from space because it's too complex to be formed by itself, and it would be disintegrated by the cosmic radiation. However, the building blocks of DNA - aminoacids and other organic compounds - have been found in meteorites, and can be detected through spectrometry in the distant molecular clouds and nebulas in the outer space.

It is possible but not certain, the answer is that DNA could have evolved on earth OR came to Earth in the ice of a comet, rest assured there is no definitive answer, many questions do not have a definitive answer and this is one of them.

I strongly recommend the link below on the subject of the "Big Bang"

Dr Joseph states the common sense obvious that the "Big Bang" never happened; however he also claims that life on Earth did originate in space, this may or may not have been true

All evidence to this point in time suggests that all (known) life (DNA too) originated on Earth.

It is too early to rule out the possibility of Earth being "seeded" with DNA long ago, but as it stands, it likely that the common proteins required to make DNA could have formed here just as easily as they could have formed anywhere else in the universe.

It seems to me that the panspermia theory as it is called over complicates matters. It is a basic tenet that given two possible solutions, the simplest is almost always the right one. This is known as Occam's Razor. All the theory does is move the question elsewhere. There is considerable evidence for the formation of life here on Earth, and so far at least, none for life existing elsewhere.

Simple amino acids and organic compounds, some of which form the building blocks of DNA, have been found in meteorites for several decades. At this time, no actual DNA has been found that did not originate on Earth.

Some have hypothesized that life on Earth originated with microorganisms that came in on a meteorite or comet, but there is no solid evidence to either support or disprove this.

DNA must have come from space since all things originated from the theoretical big bang theory..obviously the proper conditions had to have taken place for life to emerge , thus DNA can be found in all life forms.

No, that makes no sense. DNA evolved here on earth.

No I think it was discovered by scientists around 50 years ago. It came from earth.
