What happens to the transcript RNA before it leaves the nucleus?

The 5-prime end is immediately capped off with a modified form of a guanine (G) nucleotide. This 5-prime cap has at least two important functions: protect the mRNA from degradation by hydrolytic enzymes and act as an "attach here" sign for ribosomes. The 3-prime end gains a poly(A) tail consisting of 30 to 200 adenine nucleotides, which also inhibits degradation of the RNA and helps ribosomes attach to it. The poly(A) tail also seems to facilitate the export of mRNA from the nucleus.

What happens to the identity of the atom when an electron leaves the nucleus?
Electrons are not part of the atomic 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.
What never leaves the nucleus?
DNA never leaves the nucleus
Where does RNA go when it leaves the nucleus?
it goes to the nucleus
What surrounds the nucleus and controls what enters and leaves the nucleus?
The nucleolus .
What organelle controls what enters and leaves the nucleus?
nuclear ,membrane
What happens to the sugar produced in the leaves of a plant?
it is changed to starch before it can be stored in the leaves,stems,or roots.
When mRNA leaves leaves the cells nucleus what does it become associated with?
ribosome
Does moss leaves have nucleus I don't know?
Each and every plant on planet earth consists of nucleus. Therefore, Moss leaves also have a nucleus which becomes a degenerated nuclei at the time of maturity.
What happens before a RNA messenger is mature?
RNA is spliced (cut) in order to make it mature. This involves splicing out the introns and leaving the exons - these are the segments that code for a protein. This means that when mRNA leaves the nucleus, it only contains the segments that directly code for a protein.
What leaves the nucleus and moves to the cytoplasm?
protein
What surrounds the nucleus and controls and what enters and leaves it?
The nucleolus .
