What happens to mRNA when it leaves a ribosome?
in prokaryote cells RNA directly translated by ribosomes but in eukaryote we have capping polyadenylation and splicing befor translation
What molecule carries a copy of the code from out of the nucleus?
Molecules of Ribonucleic Acid (RNA) carry the instructions for assembling proteins out of the cell nucleus. Without this type of molecule, the cell cannot survive.
Where is new mRNA produced?
mRNA is produced inside the nucleus of the cell after transcription has occurred.
Is mRNA transcribed from DNA in the nucleus?
yes.
What are the three main ways through which an mRNA strand is modified between transcription and translation?
5' processing - capping 3' processing - cleavage and polyadenylation RNA splicing RNA editing
Where does polyadenylation occur?
Polyadenylation occurs at the 3' end (the back) of an mRNA strand in the nucleus of the cell. This act of polyadenylation creates a polyadenine (polyA) tail. mRNA cannot leave the nucleus of the cell unless polyadenylation occurs. PolyA tails seem to protect integrity of the mRNA molecule, which is exposed to multiple proteins that can degrade it once shipped to the cytoplasm
Where does polyadenylation take place?
PolyA (as a process) takes place in nucleus. Polyadenylated mRNA is exported to cytoplasm afterwards.
What happens right after the end of transcription?
After transcription, the mRNA produced is modified through processes like capping and polyadenylation. This modified mRNA then leaves the nucleus and enters the cytoplasm where it can be translated into a protein by ribosomes.
How is mRNA stabilized before leaving the nucleus for translation?
Before leaving the nucleus, the mRNA is modified (post-transcriptional modification). It is protected from ribonucleases by adding a 5' cap and a (3') poly A tail. These modifications help to stabilise the mRNA by preventing degradation by nucleases.
What happens to mRNA when it leaves a ribosome?

Why do you stay in the nucleus to write down the mRNA?
why did we have to stay in the "nucleus" to write down the mRNA
What does mRNA carry away from the nucleus?
Basically, mRNA carries a message away from the nucleus. The nucleus says hey, we need these proteins made, and mRNA is made by using RNA polymerase to copy the information on DNA. That mRNA then moves out of the nucleus to a ribosome, where rRNA and tRNA will interact with the mRNA, eventually resulting in the production of a fully functional protein.
Where is mRNA produce?
The nucleus.
Where does transcript take place?
In the nucleus of the cell. If the cell lacks a nucleus, then the mRNA is immediately translated without additional processing.The transcription takes place inside the nucleus. The new mRNA is then spliced and afterwards leaves the nucleus.
Where in the cell is mRNA located?
Messenger RNA, or mRNA, is transcribed from DNA in the nucleus of the cell. It is then transported to the cytoplasm.
What molecule carries a copy of the code from out of the nucleus?
Molecules of Ribonucleic Acid (RNA) carry the instructions for assembling proteins out of the cell nucleus. Without this type of molecule, the cell cannot survive.
What mRNA carries from the nucleus is?
