As far as my knowledge in both Biology and geology goes, no. Only living or dead things can have DNA. Rocks are non-living. Non-living and dead may sound similar, but they are two completely different things. Non living things have never lived. Dead things have lived, but are not longer living.
If any physical evidence of bodily hair, skin or secretions were left on the rock, yes.
There are a few downsides to DNA evidence: It has been suggested that the prominence of DNA evidence on TV shows has caused juries to expect irrefutable DNA evidence before convicting someone. This may be a problem if other forms of evidence are ignored. DNA evidence can only be obtained in instances where biological substances are left behind or exchanged. This only occurs in a minority of cases. DNA evidence sometimes only proves that the person was present at the scene - it does not always prove guilt. However, if a person's DNA is found at the scene, this may be perceived as proof that they committed the crime.
A fossil is evidence of an organisms existence, not a type of rock. Most fossils are found in sedimentary rocks.

They look like bacterias, but no alien DNA was found, so its circumstantial evidence.
It will depend on the circumstances, but generally yes. For example, if another person's DNA is found at the scene, it is strong evidence in support of being found not guilty. ----------------------------------- If another person's DNA is found at a crime scene or on a victim, it strengthens the possibility of that person's being there or in contact with the victim, but, it could depend on the circumstances and the type of evidence. For example: - If the victim's hair has been found on a hairdresser's coat, chances are that the victim could have been his client. - However, if a man's semen was found on a rape victim's underwear, chances are pretty strong, but not 100 % sure, that he was the rapist. If the rapist used a condom, than the semen could have been the result of a willing encounter before or after the rape. Generally speaking, DNA should be supported by other evidence(s) as well.

They compare the DNA of those found at the scene of the crime against any suspect. This can be achieved by using Electrophoresis.
Amber.
Blood evidence can help to identify the suspect who comitted the crime, (especially in regard to their unique DNA which is found in the blood).

There are many arguments for and against DNA evidence. One argument is that it cannot be disproved as deciding evidence.

Fossils are found most commonly in layers of sedimentary rock. This type of rock begins to form when water and wind form layers of sand and silt.
They found that all of the viral DNA and little of the protein had entered E. coli cells. Then they concluded that DNA is the hereditary molecule in viruses.
what does molecular evidence mean
DNA typing is done by scientist, finding markers in DNA samples from things like blood, hair or bone samples. They are found by designing small DNA probes that bind to the complementary DNA sequence. These bindings will create a very unique, distinctive pattern for an individual. They then take this pattern and match it up to evidence samples that were found at the scene. If one marker is the same, it doesn't give strong enough evidence, because one marker is not unique to each person, but when there are four, five or more, then the probability is very high that the evidence sample and the DNA sample taken are from the same person.
In Australian rock of about 3.5 billion years old they have found a filamentous prokaryote.
