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.

- Quick Answer. Cell transcription occurs in the nucleus of the cell where the DNA is located. Transcription is the process whereby a DNA base sequence is copied to form an RNA molecule. The production of mRNA requires a DNA template.

5 Where does transcription occur in the cell? Answer. It must occur in the nucleus where the DNA in the cell is located. However, once mRNA is produced, it leaves the nucleus and protein synthesis – translation – occurs in the cytoplasm.t must occur in the nucleus where the DNA in the cell is located.

Prokaryotic and Eukaryotic Gene Regulation Prokaryotic vs Eukaryotic Gene Expression: Prokaryotic transcription and translation occur simultaneously in the cytoplasm, and regulation occurs at the transcriptional level. Eukaryotic gene expression is regulated during transcription and RNA processing, which take place in the nucleus, and during protein translation, which takes place in the cytoplasm. Further regulation may occur through post-translational modifications of proteins.

Eukaryotic transcription Gene transcription occurs in both eukaryotic and prokaryotic cells.Unlike prokaryotic RNA polymerase that initiates the transcription of all different types of RNA, RNA polymerase in eukaryotes (including humans) comes in three variations, each encoding a different type of gene.he regulation of gene expression in eukaryotes is achieved through the interaction of several levels of control that acts both locally to turn on or off individual genes in response to a specific cellular need and globally to maintain a chromatin-wide gene expression pattern that shapes cell identity.

- Regulation of transcription in eukaryotes is a result of the combined effects of structural properties (how DNA is packaged) and the interactions of proteins called transcription factors. The most important structural difference between eukaryotic and prokaryotic DNA is the formation of chromatin in eukaryotes.truhl, K.

Contents: Transcription vs Translation In prokaryotes both transcription and translation occur in the cytoplasm due to the absence of nucleus. In eukaryote transcription occurs in the nucleus and translation occurs in ribosomes present on the rough endoplasmic membrane in the cytoplasm.

- Transcription and translation are simultaneous in prokaryotes because there is no separation between cytoplasm and nucleus. In eukaryotes, the separation prevents simultaneous transcription and translation, introducing a time lag, but also allowing processing of RNA transcripts. 9.

- 1 In eukaryotic cells, DNA and RNA synthesis occur in a different location than protein synthesis; in prokaryotic cells, both these processes occur together.  DNA is supercoiled in prokaryotic cells, meaning that the DNA is either under-wound or over-wound from its normal relaxed state.

Eukaryotic transcription Transcription is the process of copying genetic information stored in a DNA strand into a transportable complementary strand of RNA. Eukaryotic transcription takes place in the nucleus of the cell and proceeds in three sequential stages: initiation, elongation, and termination.nce the initiation complex is open, the first ribonucleotide is brought into the active site to initiate the polymerization reaction in the absence of a primer. This generates a nascent RNA chain that forms a hetero-duplex with the template DNA strand.

Where does transcription occur and where does translation occur in the cell? Transcription occurs in the nucleus, whereas translation occurs in the cytoplasm. Terms transcription and translation in biology are generally related to the DNA and its properties. Human cells replicate. In order to do that, they have to produce the same constituents for the new cell that is to be made. The only way to do that is by producing proteins. The proteins are produced in the process that is called protein synthesis.

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.

- In prokaryotes, translation of an mRNA molecule often begins before its transcription is complete (see Fig. 2). This is possible because mRNA molecules are both synthesised and translated in the same 5’ to 3’ direction and because there is no nuclear membrane to separate the 2 processes.

- 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).

Transcription - Transcription happens in the nucleus, and the RNAs produced are processed further before they are sent into the cytoplasm. - Protein synthesis (translation) happens in the cytoplasm.In prokaryotic cells, RNAs can be translated as they are coming off the DNA template, and because there is no nucleus, transcription and protein synthesis occur in a single cellular compartment.n the last couple of class periods, we have discussed the replication of the cell's DNA and the mechanisms by which the integrity of the genetic information is maintained. We now turn to the fascinating process by which information in DNA is used by the cell to direct the synthesis of RNAs and proteins.

- In eukaryotes, transcription occurs in the nucleus. RNA polymerase II transcribes the DNA forming an mRNA transcript. The mRNA is then modified. It has a 5'-cap and a 3'poly … A tail and it can also be spliced and edited by various enzymes. Once an mRNA molecule has been correctly edited it is exported out of the nucleus through nuclear pores.

Prokaryotic Transcription and Translation Prokaryotic Translation. Translation is similar in prokaryotes and eukaryotes. Here we will explore how translation occurs in E. coli, a representative prokaryote, and specify any differences between bacterial and eukaryotic translation. Initiation. The initiation of protein synthesis begins with the formation of an initiation complex.

Gene Confidence votes 9.3K. In prokaryotes (cells without nuclei), both transcription makes RNA from DNA and translation makes proteins from mRNA in the cytoplasm. In eukaryotes (cells with nuclei), transcription occurs in the nucleus, while translation occurs in the ribosomes of the cytoplasm.ere various translation factors help ribosomes to translate the DNA into protein. Translation occurs in the cytoplasm. Do not get this confused with prokaryotes. In prokaryotes, they do not have organelles and so transcription and translation are coupled in the cytoplasm...

An Introduction to Molecular Biology/Transcription of RNA and its modification In eukaryotes, RNA polymerase, and therefore the initiation of transcription, requires the presence of a core promoter sequence in the DNA. Promoters are regions of DNA that promote transcription and, in eukaryotes, are found at -30, -75, and -90 base pairs upstream from the start site of transcription.

Where does transcription occur and where does translation occur in the cell? ok, you werent specific here, so im going to answer RNA transcrition and translation. transcription occurs in the nucleus of a cell, if it has a nucleus. if the cell lacks a nucleus, then the mRNA is immediately translated without additional processing. transcription in RNA only involve portions of the molecule.

Steps of Transcription From DNA to RNA 1 Eukaryotic DNA is packed to form chromatin. 2  While RNA polymerase interacts directly with prokaryotic DNA, other proteins mediate the interation between RNA polymerase and DNA in eukaryotes. 3  mRNA produced as a result of transcription is not modified in prokaryotic cells.ranscription is the first stage of the expression of genes into proteins. In transcription, a mRNA (messenger RNA) intermediate is transcribed from one of the strands of the DNA molecule.
