Yes, eukaryotic organisms have DNA.
In prokaryotes, the DNA is circular and not contained in a membrane. In eukaryotic cells, the DNA is in the form of chromatin and reproduces differently, and it is found inside the nucleus (and mitochondria/chloroplasts).
Usually, prokaryotes are about 10X smaller than eukaryotic cells. Eukaryotes include plant, animals, protists, and fungi. The only kind of prokaryotes on Earth are bacteria. Bacteria have no nuclei; their DNA are scattered in their cytoplasm. Eurkaryotes have specifically defined nuclei, containing all the chromosomes of DNA.
by DNA fingerprinting method , DNA-DNA hybirdization or DNA sequencing. to know the sequence of DNA
DNA fingerprinting
DNA is DNA it can not be changed.
DNA Polymerase.
Chimeras. In genetic engineering, molecules of combined DNA are known as chimeras because they are produced by combining DNA from different species. Combined DNA is also known as recombinant DNA, since DNA from 2 sources has been recombined to produce it.
The enzyme that is used to bind DNA fragments together is DNA ligase. Using DNA ligase to join DNA fragments is the last step in the production of a recombinant DNA plasmid.
DNA Helicase unwinds and unzips the DNA. It separates the two strands of DNA so DNA replication can occur.
o
IT can be called * DNA duplication * DNA reproduction * DNA imitation
It is how the DNA is constructed.
