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
Why can't the DNA just bring the message to the organelle itself in transcription?
It's very important to keep your DNA from becoming damaged, thus it stays safely inside the nucleus of the cell; which will go through many lengthy processes to get it's information from the nucleus to the ribosomes for translation.
What are the differences between DNA and mRNA and how do they function differently within the cell?
DNA is the genetic material that carries the instructions for making proteins in the cell, while mRNA is a temporary copy of a specific gene that carries the instructions from the DNA to the ribosomes for protein synthesis. DNA is double-stranded and located in the cell's nucleus, while mRNA is single-stranded and found in the cytoplasm. DNA remains in the nucleus, while mRNA travels to the ribosomes to direct protein synthesis.
Why did you use RNA instead of DNA to make proteins?
In order to use DNA directly to make proteins, DNA would have to leave the nucleus, which would make it more susceptible to damage. Since it is the template for making proteins, it would be too risky to expose it to the rest of the cell.
Why can't DNA leave the nucleus?
DNA cannot leave the nucleus because it is a vital molecule that contains important genetic information needed for the cell to function properly. The nucleus acts as a protective barrier to ensure that the DNA remains safe and undamaged. If DNA were to leave the nucleus, it could be exposed to harmful substances or processes that could potentially harm the cell.

Proteins are made in the cytoplasm but DNA never leaves the nucleus of a cell how does DNA control how proteins are made?
DNA controls protein synthesis through a process called transcription and translation. First, a specific segment of DNA is transcribed into messenger RNA (mRNA) in the nucleus. The mRNA then exits the nucleus and enters the cytoplasm, where ribosomes translate the mRNA sequence into a protein. Thus, while DNA remains in the nucleus, it indirectly dictates protein production by providing the instructions carried by mRNA.

A chemical reaction in a living cell occurs in the presence of a specific protein molecule The concentration of this protein molecule remains the same before and after the reaction This protein mole?
This protein molecule is likely an enzyme, which facilitates the chemical reaction by lowering the activation energy required for the reaction to occur. Enzymes remain unchanged after the reaction and can be reused to catalyze multiple reactions. They are specific to the reaction they catalyze and are essential for the proper functioning of the cell.

What happens to a enzyme molecule after the synthesis reaction is done?
After an enzyme molecule completes a synthesis reaction, it typically remains unchanged and is free to catalyze additional reactions. Enzymes are not consumed in the reaction; instead, they can repeatedly bind to substrate molecules and facilitate the formation of products. This ability allows a single enzyme molecule to participate in many catalytic cycles, enhancing the efficiency of biochemical processes in the cell. Ultimately, enzymes can be regulated or degraded if they are no longer needed or if they become damaged.

How does the endoplasmic reticulum help maintain the homeostasis?
The endoplasmic reticulum provide the pathways in the cell cytoplasm for messages to be send by the nucleus to every part of the cell. This helps in conducting several metabolic activities by different cell organelles to maintain the homeostasis in the cell.
Why does the nucleus of carbon remain unchanged when it forms methane?
The nucleus of carbon remains unchanged when it forms methane because only the outer electrons are involved in bonding to hydrogen atoms to form the methane molecule. The nucleus contains protons and neutrons, which are not involved in chemical reactions.
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.
Where does DNA go after released from the template?
DNA remains in the nucleus.
