Does RNA editing occur in the cytoplasm of the cell?

No it does not


Does RNA editing occurs in the cytoplasm of the cell?

Mostly, RNA editing occurs in nucleus. RNA editing such as C to U deamination can be accompanied by APOBEC proteins in the nucleus. Insertion or deletion of bases also reported. In addtion, RNA edition known to occur in mitochondria and plastids.


Where does RNA editing occur in the cell?

in the nucleus of the cell when the mrna causes the DNA to spilt in two and then it Paris up with one side of the DNA and then the RNA goes back out into the cytoplasm


Rna editing occurs in the cytoplasm of the cell?

This is True! RNA editing is different than pre-mRNA processing, which takes place in the nucleus: Processing includes the removal of the introns (splicing), cleavage at the poly A site, and poly-adenylation. Then RNA translation is effected at the Cytoplasmic Ribosomes.RNA editing, which is different, has been shown to occur in the cytosol, the nucleus, and inside the mitochondria.


Is the following true or false rna editing occurs in the cytoplasm of the cell?

No


Where is RNA located within a cell?

RNA is located in the nucleus of the cell and throughout the cytoplasm.


Is the following sentence true or false- rna editing occurs in the cytoplasm of a cell?

False. Mature RNA editing takes place on the spliceosomes in the nucleus of the cell before it is exported ti the cytoplasm. Introns cut out, exons spliced together.


Where does translation occur in the cell?

RNA translation occurs on the ribosome.


What is an asRNA?

An asRNA is an antisense RNA, a single-stranded RNA which is complemenetary to a messenger RNA strand transcribed within a cell.


What nucleic acid translates the genetic code that is contained within a cell RNA or DNA?

RNA


What is RNA editing?

RNA editing is when an RNA molecule is changed (edited) through a chemical change in the base make up. There are various types of RNA editing - namely insertions/deletions and switching bases like Cytidine to Uridine or Adenosine to Inosine (properly known as deamination). RNA editing has been observed in tRNA, rRNA and mRNA (interestingly enough all of them have to do with protein synthesis) of eukaryotes (in the cell nucleus, cytosol, mitochondrion, and chloroplast) but not in prokaryotes - which is interesting because both the mitochondrion and chloroplast are believed to be descended from prokaryotes.


What is translation and where does it occur in the cell?

It occurs in the nucleus of the cell. Translation refers to the process by which RNA is translated into proteins.


Which nucleic acid translates the genetic code that is contained within a cell?

RNA translates the genetic code that is contained within a cell.


Does RNA editing eliminate introns?

No. The process which eliminatesintrons is called 'splicing'. This process is mediated by the protein complex called a spliceosome and probably occurs simultaneously with RNA editing. RNA editing is the addition, removal or substitution of bases in an RNA molecule after it has been synthesised, and critically can occur in organisms which lack introns. There are 3 main types of RNA editing: 1, Addition or removal of Uracil residues. Seen in the primary transcripts in trypanosome mitochondria (does not appear in multicellular organisms). 2, Cytosine -> Uracil Editing. Seen in mRNAs in some animals and plant mitochondria. 3, Adenosine -> Inosine. Seen in animal mRNAs. (Inosine is a very rare base which you get from the deamination of adenosine)


What is purpose of rna editing?

RNA editing take place in order to insure that only the codons that code for a particular gene will be translated into a protein.


Where in the cell does RNA transcription occur?

It is inside the nucleus! nascent RNA is further processed there and then moves through the small nuclear pores to the cytoplasm.


Three cellular functions that occur in the nucleus?

DNA synthesis, RNA synthesis and cell reproduction


What organelle produces RNA?

The nucleolus organelle produces RNA. Organelles are found within a cell and each one carries out a specific function.


Description of a ribosome?

Ribosomes consist of RNA and proteins. They are responsible for assembling the proteins within a cell. Ribosomes are cell organelles.


Where in the eukaryotic cell does transcription occur?

Transcription occurs in the cell nucleus and where DNA is housed. Transcription is the first step of gene expression, in which a particular segment of DNA is copied into RNA by the enzyme RNA polymerase.


Where in the cell do replication translation and transcription occur?

Transcription of DNA into RNA happens in the cell nucleus. Translation of RNA into proteins can happen in the cytoplasm, or right into the lumen of the ER, threaded directly off a ribosome.


What happens if there is a mistake when making RNA or a protein?

Nothing too horrible will occur if RNA or proteins are messed up. Likely the protein will have no biological function. However, if there is a mistake in DNA, then cell death or even cancer can occur.


What are the three cellular functions that occur in the nucleus?

The nucleus houses the DNA and RNA required for many of the functions of the cell. It works essentially as the command center of the cell, responsible for sending the RNA to where it needs to be, as well as for the duplication of the DNA during cell division.


Does mitochondria contain RNA?

Mitochondria are organelles that contain their own genome, the DNA and RNA. They are referred to as the powerhouse of the cell where biochemical processes of respiration and energy production occur.


Why is RNA needed in a cell?

RNA is needed in a cell for DNA replication.
