Answer – Majority of the DNA in a eukaryotic cell is located in its nucleus. However, some DNA can also be found in the mitochondria and plant chloroplasts.
Explanation:
Eukaryotic cells make up a host of single-celled and multi-celled organisms ranging from fungi to animals and plants. They differ from the more primitive prokaryotic cells due to the presence of a membrane around their nucleus and other organelles.
Most of the DNA in each eukaryotic cell is housed in its nucleus. And since abundant DNA needs to be stored in the very small nucleus of each cell, lengthy DNA strands are condensed into a material called chromatin. It is this chromatin that is made of the substance contributing to chromosomes – the carriers of genetic information.
In addition to the nucleus, DNA can also be found in the mitochondria (which produce energy in eukaryotic cells) and chloroplasts (which convert solar energy into chemical energy in plant cells). Some scientists believe that these organelles also contain DNA because they may have existed by themselves as separate cells several million years ago and, over time, been engulfed by larger cells.
