yes, but many viruses do not have DNA genome, but RNA genome.
Genomes are found in the nucleus of eukaryotic cells, which contain the DNA responsible for encoding all the genetic information of an organism. In prokaryotes, such as bacteria, genomes are found in the nucleoid region, which is not a true nucleus but contains the DNA. However, some organisms also have genomes in other cellular compartments, such as mitochondria or chloroplasts.
eg for organisms which carry recombinant DNA : Ecoli
No, DNA is found in most living things (one of the very few exceptions being viruses, which is debatable if they are living), including plants and bacteria.
The comparison of the genomes of different organisms can be done by DNA profiling of those organisms. This includes the methods like electrophorosis, PCR[poly chain reaction] etc.

If we are talking about viruses and their RNA genomes(eg:HIV), the negative strand DNA synthesis by reverse transcriptase occurs in the host cells, when the virus infects the host. And then, plus DNA formed by complementing this minus DNA.
There are several differences for example; most DNA viruses use the DNA polymerases of of the host cell to synthesize new genomes along the templates provided by the viral DNA, in contrast to replicate their genomes, RNA viruses use virally encoded polymerases that can use RNA as a template. RNA viruses usually retain their RNA within capsids, whilst DNA viruses are less "packaged" usually retained within say a head, or a capsomere. The main difference of course, is that DNA viruses contain either a doubled stranded DNA (dsDNA) or a single stranded (ssDNA), and RNA viruses contain dsRNA or ssRNA. There are of course several other differences, but these are the ones I know of.
Some viruses have single stranded DNA molecules. These viruses do not have the machinery to synthesise the DNA on their own. They insert their DNA in a living cell where the DNA synthesis takes place.
No; genomes are made from DNA or RNA, which are nucleic acids,
DNA is double stranded Except in bacteria and some viruses and chloroplast and mitochondrial DNA
No. Viruses are not cells. They invade cells to get the materials to copy their DNA. Many people do not consider viruses to be truly alive.
