The replication process is similar for the DNA of prokaryotes and eukaryotes but this process is simple in prokaryotes. The eukaryotic genome is larger and more complex as compared to the prokaryotic genome. In eukaryotes and archaea, transcription initiation is far more complex. The main difference is that eukaryotic polymerases do not recognize directly their core promoter sequences. In eukaryotes, a collection of proteins called transcription factors mediate the binding of RNA polymerase and the initiation of transcription. DNA contains instructions made of chemical code for the production of protein, determining a cells structure and function. Where is DNA located in prokaryotic cells Cytosol/cytoplasm Although both can relax positive and negative supercoils.

Intrinsically curved DNA structures are often found in or around transcriptional control regions of eukaryotic genes, and curved DNA may be common to all class I gene promoters. Although not all class II gene promoters contain curved DNA structures, both TATA-boxcontaining and TATA-box-less promoters often contain such structures. Furthermore, several studies have suggested that the TATA box 2005-02-02 The process in which genetic material is transferred from DNA to RNA is called transcription.in this process DNA strand is used as a template and mRNA is synthesized. The enzyme that take part in transcription is RNA polymerase.During cell division the whole genome of living organism is replicated a lot of time, but transcription take place only of short portion of genome.

The number of DNA polymerases in eukaryotes is much more than in prokaryotes: 14 are known, of which five are known to have major roles during replication and have been well studied. They are known as pol α, pol β, pol γ, pol δ, and pol ε. The essential steps of replication are the same as in prokaryotes.

The DNA N 6-methyladenine (6mA) modification is a prevalent epigenetic mark in prokaryotes, but the low abundance of 6mA in eukaryotes has recently received attention.The possible role of 6mA as an epigenetic mark in eukaryotes is starting to be recognized. This review article addresses the epigenetic roles of 6mA in eukaryotes. that DNA is made in the bacteria.

Eukaryotic DNA is bound to proteins known as histones to form structures called nucleosomes. During initiation, the DNA is made accessible to the proteins and enzymes involved in the replication process. There are specific chromosomal locations called origins of replication where replication begins.

The E. coli genome consists of a single, circular chromosome containing 4.6 Mb. This genome encodes approximately 2000 proteins. In comparison, the genome within a human cell contains 23 pairs of chromosomes ranging in DNA replication is the process by which two identical replicas of a DNA are obtained from the original DNA strand. The DNA replicates before the cell division occurs. Both prokaryotic and eukaryotic DNA replicate in a semi-conservative manner.

Eukaryotic DNA replication is a conserved mechanism that restricts DNA replication to once per cell cycle. Eukaryotic DNA replication of chromosomal DNA is central for the duplication of a cell and is necessary for the maintenance of the eukaryotic genome . DNA replication is the action of DNA polymerases synthesizing a DNA strand complementary to the original template strand. 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. It is present in this compartment in the form of linear chromosomes that together constitute the genome. Recent advances have expanded our understanding of the processes underlying the establishment, maintenance, and elaboration of DNA methylation patterns in eukaryotes.

In support of these bio-chemical studies, some temperature-sensitive mutations in the gene encoding the large subunit of S. cerevisiae RPA showed synthetic lethality, a form of genetic interaction, with mutations in genes encoding pol ﬁ, primase, or pol – (58). The Initiation of DNA Replication in Eukaryotes will focus on how DNA replication is initiated in eukaryotic cells. While the concept of replication initiation is simple, its elaborate regulation and integration with other cell processes results in a high level of complexity. 6.2: Replication in Eukaryotes Overview.
