Answer:
Although they are not closely related, as vertebrate animals, they share some characteristics and belong to the same Phylum.
Explanation:
Tigers and goldfish belong to different Classes. Tigers (<em>Panthera tigris</em>) belong to the Class Mammalia, while goldfish (<em>Carassius auratus</em>) belong to the Class Actinopterygii. However, they both belong to the Phylum Chordata.
Chordates share particular characteristics, such as a dorsal neural tube, a notochord, a bilateral symmetry, circulatory system, amongst other features. They are divided into different groups of vertebrates as well: mammals, birds, amphibians, reptiles, and fish. And, according to evolutionionary studies, over 300 million years ago, the first vertebrates that lived on land (amphibians) evolved from a lobe-finned fish species, which eventually led to the evolution of mammals that adapted to terrestrial environments.
Therefore, even though goldfish and tigers may seem completely different, they share similar characteristics. Plus, they are vertebrates that belong to the same phylum.
In eukaryotic cells the DNA can be found in the nucleus mainly. so DNA replication takes place in the nucleus during the S phase of the cell cycle.
Also in eukaryotic cells there are mitochondria and chloroplasts (plants) and these have circular DNA and they also get replicated (according to their own mechanism).
Prokaryotic cells don't contain a nucleus. They do not contain DNA in the cytoplasm and thus the DNA replication will take place here.

A quasar is formed when a super massive black hole has enough material around it to fall in it's accretion disk.
