How do materials enter and leave the nucleus?
Materials enter and leave the nucleus through nuclear pore complexes in the nuclear envelope. Large molecules, such as proteins and RNA, are actively transported into and out of the nucleus through these pores using specific transport proteins. Small molecules, like ions and small proteins, can freely diffuse through the pores.
What part of a plant cell the cell wall or the cell membrane what enters or leave the cell?
The cell membrane controls what enters or leaves the cell.
What is the nuclear membrane and what does it do?
The nuclear membrane is a double membrane surrounding the chromosomes of a eukaryotic cell.Together with associated structures, it is called the nuclear envelope. Perforations in the double membrane are termed pores; each is surrounded by a group of proteins collectively called the nuclear pore complex.The nuclear membrane defines the limit of the organelle called the nucleus. The membrane is broken into fragments during the first phase (prophase) of nuclear division. The fragments travel through the endoplasmic reticulum to the poles of the dividing cell, and are used to form the nuclear membranes of the daughter-cells.The pores permit large molecules to enter and leave the nucleus. For example, after transcription messenger RNA passes through a pore on its way to the cytoplasm for translation. And proteins synthesized in the cytoplasm enter the nucleus via pores before being incorporated in ribosome subunits being assembled in the nucleolus. These subunits subsequently leave the nucleus through the pores.
Controls what enters and leaves the cell?
The nucleus controls the whole of the plant cell, including leaf cells. The leaf turns brown and falls off because the cells inside it eventually die. A new leaf grows, controlled by the nucleus, when new cells are formed.
Can RNA leave the nucleus?
Yes, RNA can leave the nucleus.
What is the function of a leave?
it surrounds the baby plant
Which one can leave the nucleus: DNA or RNA?
RNA can leave the Nucleus.
How is the genetic code transferred from the nucleus into the cytoplasm?
The genetic code is transcribed in the nucleus to produce messenger RNA (mRNA). The mRNA then exits the nucleus through nuclear pores and enters the cytoplasm, where it serves as a template for protein synthesis at the ribosomes.
What are the three parts of a cell and what there jobs are?
the 3 parts of a cell are : 1 Nucleus- this controls what happens inside the cell . 2 Cell Membrane - this controls what substances enter and leave the cell 3 Cytoplasm - this is where the chemial processes occur
Which part of a cell controls what gets in and out of the cell?
The plasma membrane / cell surface membrane. The phospholipid bilayer prevents certain substances passing straight through, so protein channels and other mechanisms control what does and does not pass in and out of the cell.
Is RNA able to leave the cell nucleus?
Yes, RNA is able to leave the cell nucleus.
Can DNA or RNA leave the nucleus?
Yes, both DNA and RNA can leave the nucleus. RNA regularly leaves the nucleus to carry out various cellular functions, while DNA can also leave the nucleus during processes like DNA replication and repair.
