- Confidence votes 7.7K. Most of the DNA in a eukaryotic cell is in the nucleus, and that is where DNA replication and transcription occur. In eukaryotic cells, mitochondria and chloroplasts also contain DNA, which performs replication and transcription inside these organelles. 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.ost of the DNA in a eukaryotic cell is in the nucleus, and that is where DNA replication and transcription occur.

Cell division in Bacteria; in Eukaryotes Replication of the chromosome starts at the origin attached to the cell wall, near the midpoint of the cell. Replication occurs bidirectionally around the chromosome, as the cell elongates.

Where is DNA located within a prokaryotic cell? t 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.rokaryotes have no cell nucleus and no membrane enclosed organelles. Prokaryotic DNA can be found in a coiled loop floating in the cytoplasm in a region called the nucleoid (meaning nucleus-like).

Genome Packaging in Prokaryotes: the Circular Chromosome of E. coli Prokaryotic cells do not contain nuclei or other membrane-bound organelles. In fact, the word prokaryote literally means before the nucleus.. The nucleoid is simply the area of a prokaryotic cell in which the chromosomal DNA is located. This arrangement is not as simple as it sounds, however, especially considering that the E. coli chromosome is several orders of magnitude larger than the cell itself.

Where does translation take place in prokaryotic cells? Making the world better, one answer at a time. In Prokaryotes, both Transcription and Translation occur in the cytoplasm as opposed to Eukaryotes where transcription occurs in the membrane bound nucleus and translation occurs outside in the cytoplasm.

Learn About Prokaryotic Cells Most prokaryotes reproduce asexually through a process called binary fission. During binary fission, the single DNA molecule replicates and the original cell is divided into two identical cells. Steps of Binary Fission

- Prokaryotic gene expression (both transcription and translation) occurs within the cytoplasm of a cell due to the lack of a defined nucleus; thus, the DNA is freely located within the cytoplasm. Eukaryotic gene expression occurs in both the nucleus (transcription) and cytoplasm (translation).

How DNA Works Where DNA replication occurs depends upon whether the cells is a prokaryote or a eukaryote (see the RNA sidebar on the previous page for more about the types of cells). DNA replication occurs in the cytoplasm of prokaryotes and in the nucleus of eukaryotes. Regardless of where DNA replication occurs, the basic process is the same. The structure of DNA lends itself easily to DNA replication. Each side of the double helix runs in opposite (anti-parallel) directions.

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).

Cells Can Replicate Their DNA Precisely In the prokaryotic bacterium E. coli, replication can occur at a rate of 1,000 nucleotides per second. In comparison, eukaryotic human DNA replicates at a rate of 50 nucleotides per second. In both cases, replication occurs so quickly because multiple polymerases can synthesize two new strands at the same time by using each unwound strand from the original DNA double helix as a template. One of these original strands is called the leading strand, whereas the other is called the lagging strand.

Difference Between Prokaryotic and Eukaryotic DNA Replication • In eukaryotes, multiple replication sites are present in a single DNA molecule whereas, in prokaryotes, a single replication site is present in the circular DNA molecule. • In prokaryotes, DNA replication involves three polymerase enzymes; namely, DNA polymerase I, DNA polymerase II, and DNA polymerase III.rokaryotic vs Eukaryotic DNA Replication. According to the Watson and Crick model suggested for DNA, one strand of DNA is the complement of the other strand; hence each strand acts as a template for the formation of a new strand of DNA. This process is known as DNA replication.

Genome Packaging in Prokaryotes: the Circular Chromosome of E. coli 1 Because prokaryotic DNA can interact with the cytoplasm, transcription and translation occur simultaneously. 2  Most prokaryotes contain only one copy of each gene (i.e., they are haploid). 3  Nonessential prokaryotic genes are commonly encoded on extrachromosomal plasmids.

How DNA Works DNA replication occurs in the cytoplasm of prokaryotes and in the nucleus of eukaryotes. Regardless of where DNA replication occurs, the basic process is the same. The structure of DNA lends itself easily to DNA replication. Each side of the double helix runs in opposite (anti-parallel) directions. The beauty of this structure is that it can unzip down the middle and each side can serve as a pattern or template for the other side (called semi-conservative replication).
