- Answer It is located all throughout the cytoplasm. Prokaryotic cells do not have a nucleus so the DNA is located in the cytoplasm. The DNA in prokaryotic cells is also usually found in a circular ring that is coiled up into figure eights called supercoils.

Eukaryotic Cells In prokaryotes, the DNA (chromosome) is in contact with the cellular cytoplasm and is not in a housed membrane-bound nucleus. In eukaryotes, however, the DNA takes the form of compact chromosomes separated from the rest of the cell by a nuclear membrane (also called a nuclear envelope).Eukaryotic cells also contain a variety of structures and organelles not present in prokaryotic cells.ver time, portions of the DNA from the other prokaryote remaining in the cytoplasmic part of the cell may or may not have been incoporated into the new eukaryotic nucleus (Figure 3). Figure 3: Origin of a eukaryotic cell. A prokaryotic host cell incorporates another prokaryotic cell.

DNA in pro-/eukaryotes In eukaryotic cells, like in the maize cell shown here, DNA is located in the nucleus, the mitochondria and the chloroplasts (occuring only in plants and some protists). The nucleus contains most DNA. 2  It is present in this compartment in the form of linear chromosomes that together constitute the genome. 3  These chromosomes are identical and equal in number in all cells of an individual (except reproduction cells and mutated cells).

Where is DNA located in the Eukaryotic cell ? Report Abuse. DNA may be located in two particular locations within a Eukaryotic cell. In the nucleus and in the mitochondria (and chloroplast). However, DNA found in the mitochondria (and chloroplast) are similar in structure to those found in prokaryotic cells.You should be more specific the next time you ask a question like this.Source(s): http://www.cod.edu/PEOPLE/FACULTY/FANCHE...eport Abuse.

- DNA is mainly found in the nucleus of the cell. Of course, it can also be found in other organelles such as the mitochondria (therefore it is called mitochondrial DNA). 1 person found this useful.Edit.f the cell is a prokaryote, meaning it lacks a nucleus and is usually less complex, then the DNA is contained in a circle-like plasmid that forks off to replicate, located in the cytoplasm.

Chapter 27 - Prokaryotes 1 More prokaryotes inhabit a handful of fertile soil or the mouth or skin of a human than the total number of people who have ever lived. 2  Prokaryotes are wherever there is life. 3  They thrive in habitats that are too cold, too hot, too salty, too acidic, or too alkaline for any eukaryote. On average, a prokaryote has only about one-thousandth as much DNA as a eukaryote. 2  In the majority of prokaryotes, the genome consists of a ring of DNA with few associated proteins. 3  The prokaryotic chromosome is located in the nucleoid region.

DNA In eukaryotes, the chromosomes are located in the nucleus, although DNA also is found in mitochondria and chloroplasts. In prokaryotes, which do not have a membrane-bound nucleus, the DNA is found as a single circular chromosome in the cytoplasm. Some prokaryotes, such as bacteria, and a few eukaryotes have extrachromosomal DNA known as plasmids, which are autonomous, self-replicating genetic material.

- The nucleoid is the region of a prokaryotic cell that houses the primary DNA. This lesson briefly discusses the nucleoid and its characteristics, and how it compares to the nucleus of the eukaryotic cell.s the cells grow, the DNA in the nucleoid may extend into the cytosol, or cellular fluid. The nucleoid region may also contain proteins, enzymes, which are biological catalysts, and RNA. These proteins are necessary for several processes that take place in this region.

- Usually, prokaryotic cells lack internal membranes and membrane-bound organelles. In addition, the DNA of eukaryotic cells is enclosed within a membrane-bound nucleus, while the DNA of prokaryotic cells is located in the cytoplasm. During this lab, you will use the brightfield microscope to examine and compare the features of several types of prokaryotic cells, and several types of eukaryotic cells.

- Though prokaryotic cells do not have a nucleus, they do have DNA. This DNA is found freely in the cytoplasm of the cell, most times wrapped in a tight coil. Endoplasmic Reticulum. The endoplasmic reticulum is a very important organelle in the cell and is found in both animal and plants cells. It is responsible for protein and lipid synthesis. There are 2 types of endoplasmic reticulum: rough and smooth.

Cell (biology) They are simpler and smaller than eukaryotic cells, and lack membrane-bound organelles such as the nucleus. Prokaryotes include two of the domains of life, bacteria and archaea. The DNA of a prokaryotic cell consists of a single chromosome that is in direct contact with the cytoplasm. The nuclear region in the cytoplasm is called the nucleoid.

Where does transcription occur in prokaryotic cells? Transcription is the process of coding for RNA along genetic sequence of DNA. In prokaryotes it occurs along the circular DNA lying in nucleoid region within cell. Prokaryotic cells lack nucleus. Inside the prokaryotic cell cytoplasm a naked DNA is present: the prokaryotic DNA is double helical and circular. The area within prokaryotic cytoplasm is called nucleoid where this circular DNA is present.

Prokaryotic Cell Structure and Function As in eukaryotic cells, the prokaryotic chromosome is intimately associated with special proteins involved in maintaining the chromosomal structure and regulating gene expression. In addition to a single large piece of chromosomal DNA, many prokaryotic cells also contain small pieces of DNA called plasmids.

Prokaryotic Genomes Prokaryote cell (right) showing the nucleoid in comparison to a eukaryotic cell (left) showing the nucleus. The nucleoid (meaning nucleus-like) is an irregularly-shaped region within the cell of a prokaryote that contains all or most of the genetic material, called genophore.n contrast to the nucleus of a eukaryotic cell, it is not surrounded by a nuclear membrane. The genome of prokaryotic organisms generally is a circular, double-stranded piece of DNA, of which multiple copies may exist at any time. The length of a genome widely varies, but generally is at least a few million base pairs.

Chapter 27 - Prokaryotes Nearly all prokaryotes have a cell wall external to the plasma membrane. 1  In nearly all prokaryotes, a cell wall maintains the shape of the cell, affords physical protection, and prevents the cell from bursting in a hypotonic environment. On average, a prokaryote has only about one-thousandth as much DNA as a eukaryote. 2  In the majority of prokaryotes, the genome consists of a ring of DNA with few associated proteins. 3  The prokaryotic chromosome is located in the nucleoid region.

Prokaryotic Cell Structure and Function All prokaryotic cells contain large quantities of genetic material in the form of DNA and RNA. Because prokaryotic cells, by definition, do not have a nucleus, the single large circular strand of DNA containing most of the genes needed for cell growth, survival, and reproduction is found in the cytoplasm.

Chromatin The primary protein components of chromatin are histones that compact the DNA. Chromatin is only found in eukaryotic cells (cells with defined nuclei). Prokaryotic cells have a different organization of their DNA (the prokaryotic chromosome equivalent is called genophore and is localized within the nucleoid region).The structure of chromatin depends on several factors.hromatin is only found in eukaryotic cells (cells with defined nuclei).

Where in the cell do DNA replication and transcription occur? In prokaryotic cells there is no nucleus. The DNA is in a region of the cytoplasm called the nucleoid, and that is where DNA replication and transcription occur in these cells.
