Does RNA stay in the nucleus?
The RNA that leaves nucleus is called mRNA (messenger RNA) molecule. The DNA molecule is first of all transcribed by use of general transcription factors to gives us a mRNA molecule. Now this mRNA molecule before leaving the nucleus undergoes RNA processing where all the interons - regions on mRNA that do not code for any protein are cut out by using spliceosomes. The modified mRNA molecule can now leave the nucleus.boogus
How does a ribosome produce protein in a Cell?
Ribosomes start protein synthesis in the cytoplasm. Synthesis is completed either in the cytoplasm or in the lumen of the rough endoplasmic reticulum.All proteins begin as polypeptides (chains of amino acids). The synthesis of a chain starts when a free (unattached) ribosome begins to move along a molecule of messenger RNA (mRNA) in the cytoplasm.Once a small number of amino acids have been incorporated into the chain, large molecules in the cell "inspect" the chain. Certain sequences of amino acids are recognized as marking the chain for synthesis in the lumen of the rough endoplasmic reticulum (ER).If the chain has one of these sequences, the mRNA and ribosome are moved to the ER and the ribosome is fixed in the ER membrane in such a way that the mRNA remains in the cytoplasm but the polypeptide chain is in the lumen of the ER. It is in the lumen that the chain is completed, and subsequently coils and folds to form the finished polypeptide.If, on the other hand, the chain does not have one of these marker sequences, synthesis of the chain and its subsequent coiling and folding all take place in the cytoplasm.
What can be found in the nucleus?
The nucleus contains nearly all the cell's DNA. * In the nucleus are chromosomes. Each chromosome consists of one (or, after replication, two) molecule of DNA, with proteins, most of which are histones, along its length. One region of the nucleus is the nucleolus, in which most of the genes for synthesizing ribosomal RNA are found.
Why do you think that DNA always remains inside of the nucleus?
DNA never leaves the nucleus because it is so important for the cell. The DNA leaving the nucleus would be like a brain leaving a head. It is what controls the cell and without the cell can not function.
What is the difference between messenger RNA and transfer RNA?
* Both consist solely of RNA. * Both are single-stranded. * Both are formed by complementary base pairing using a segment of DNA as a template. * Both play crucial roles in the synthesis of polypeptides in accordance with the information stored in DNA. * mRNA carries the code for the primary structure of a polypeptide; tRNA does not carry code. * The code in mRNA takes the form of a series of codons (each codon, like the codons in DNA, consisting of three adjacent nucleotides and coding for one amino acid); tRNA has a single anticodon, which, as its name implies, is positioned opposite one of the mRNA codons during translation. An anticodon, like a codon, consists of three consecutive nucleotides. * mRNA remains essentially a linear, unfolded molecule; tRNA folds back on itself in such a way that there are stretches of complementary base pairing. * A molecule of tRNA attaches to an amino acid and transports it to a ribosome; mRNA has no such transport role.

Where does DNA go after released from the template?
DNA remains in the nucleus.
Did the atoms have a nucleus that always remains the same?
no they dont cause they just dont.
Is the atom that remains after the nucleus disintegrate larger of smaller than the original atom?
smaller
Which part of the atom remains the same during physical and chemical changes?
i believe it is the nucleus.
The atom that remains after a nucleus disintegrates is what?
smaller than the original atom and possibly radioactive
Where is the nucleus located in a plant cell?
Unlike the animal cell where the nucleus is located in the middle. The plant cells vacuole is in the center. The nucleus is pushed off to the side but remains inside the cell wall.
The nucleus that remains from an original star when the rest of the stars has blown away is called?
Neutron star
What remains after the ATP molecule splits to release energy?
Go to the blood stream to drve the cells
