How does the MRNA get out of the nucleus?
mRNA is transported out of the nucleus through nuclear pores in a process called nuclear export. Specific proteins recognize and bind to the mRNA molecules, facilitate their transport through the nuclear pores, and into the cytoplasm where they can be translated into proteins.
What happens after mRNA is transcribed?
After mRNA is transcribed, it undergoes post-transcriptional modifications, such as the addition of a cap and poly-A tail. It then exits the nucleus and enters the cytoplasm where it binds to ribosomes for translation, which results in the synthesis of a protein based on the mRNA sequence.
What regulates protein production in the nucleus?
First a primary transcript strand is copied off a DNA strand in the nucleus in a process called transcription. The DNA strand acts as a template for the newly created primary transcript strand. The primary transcript is made up of introns and exons. The introns are taken out and the exons are binded together by enzymes. THis new strand of exons is called messenger RNA or mRNA. Next the mRNA strand leaves the nucleus through the nuclear pores, and binds to a ribosome. Each base triplet on the mRNA strand is known as the codon. The codon binds to an anti-codon which is found on a unit of transfer RNA. The transfer RNA (tRNA) brings with it a particular amino acid that is coded for to the ribosome. The tRNA then exits the ribosome, as the amino acid it brought binds to the next amino acid, forming a polyeptide (protein) chain. This process continues until a stop sequence is reached, where the protein chain is released from the ribosome and protein synthesis is complete. Some notable facts are that the triplet sequence that initially binds to the ribosome (the start sequence) is always AUG, and the three stop sequences are UAA, UAG and UGA.
What is the city analogy for a nuclear membrane?
The city analogy for a nuclear membrane is like a security wall around a city. Just as a security wall protects the city by controlling what enters and exits, the nuclear membrane surrounds the nucleus of a cell and regulates the passage of molecules in and out of the nucleus to maintain cellular function and integrity.
Molecular biologists have determined that during protein synthesis that the messenger RNA exits the nucleus through small openings in the nuclear envelope These openings are known as?
nuclear pores. They allow selective passage of molecules, including messenger RNA, between the nucleus and the cytoplasm during protein synthesis.
What are some some characteristics of a nucleus?
The nucleus is the control center of a cell, containing genetic material like DNA. It is surrounded by a double membrane called the nuclear envelope that regulates what enters and exits the nucleus. The nucleus also contains the nucleolus, which plays a role in ribosome production.
What are exits called in UK?
Exits are called exits, or way out

How do you beat level 26 on 100 exits?
Just download the app called Cheats for 100 exits.
What structure is found in both animal and plants cells?
Both animal and plant cells contain a nucleus, which houses the cell's genetic material and controls its activities. The nucleus is surrounded by a nuclear membrane that helps regulate what enters and exits the nucleus.
An ion that exits by itself is called a what?
Monatomic Ion, because Mono means One (1)
What is the hole at which the bullet exits a gun?
This is called the "muzzle" of the gun.

What is another part of the cell that has the same job as the nucleolus?
The nuclear membrane also plays a role in regulating what enters and exits the nucleus, similar to the nucleolus.

What is food called after exits the stomach?
It is called chyme once it gets out of the stomach into the small intestin.
What allows the RNA to exit the nucleus?
mRNA exits the nucleus after it binds to TAP/p15 protein. This protein helps the mRNA through the hydrophobic nuclear pore. Other RNAs bind to Exportine-proteins, which help them to pass the pore.
