Functions
This type of RNA is made in the nucleolus and is a key component of ribosomes
What is rRNA?
A double membrane that separates the nucleus from the cytoplasm
What is the Nuclear Envelope?
This organelle is directly connected to the outer membrane of the nucleus and is involved in protein synthesis, where mRNA from the nucleus is translated into proteins
What is the Rough ER?
Genes relocating from their correct position in the nucleus causes malfunctions
What is True?
True or false, the nucleolus can change size
What is True?
This process, carried out by the nucleolus, involves the production of ribosomal RNA (rRNA) from the DNA template
What is rRNA synthesis?
Numerous openings in the nuclear envelope, control movement of substances between nucleus and cytoplasm
What are Nuclear Pores?
The nucleolus interacts with this organelle by sending ribosomal subunits out to the cytoplasm, where they combine with proteins to form functional ribosomes
What are ribosomes?
If the nuclear envelope breaks, it does not have the ability to reseal
What is false? - It can reseal
The first cell organelle found by scientists
What is the Nucleus?
After rRNA is synthesized in the nucleolus, it combines with ribosomal proteins to form these, which are essential for protein synthesis
What are ribosome subunits?
The spherical body that produces ribosomes
What is the Nucleolus?
The nucleus communicates with this organelle via nuclear pores, exporting mRNA for translation into proteins and receiving proteins involved in DNA repair and replication
What is the cytoplasm?
If the nucleus is removed from the cell, this happens
What is the immediate death of the cell?
During what process does the Nuclear envelope break down
What is Mitosis?
The nucleolus plays an important role in this aspect of cell life, helping to coordinate ribosomal RNA production with cell division and growth
What is cell cycle regulation?
The cell's hereditary units, control activities and structure of the cell
What are Genes?
The nucleus and this organelle cooperate to ensure that newly synthesized proteins are folded and modified, often in preparation for secretion or insertion into the cell membrane
What is the Golgi apparatus?
A break in the nuclear envelope can cause
What is Damaged DNA?
How long in feet, is there of DNA in the nucleus
What is 6 feet of DNA?
When a cell experiences stress, the nucleolus can become involved in this type of response, helping the cell cope with damage or even initiate cell death when necessary
What is stress response or nucleolar stress?
Long molecules of DNA combined with protein molecules
What are Chromosomes?
This powerhouse of the cell relies on genetic instructions from the nucleus to regulate cellular energy production, particularly during processes like cellular respiration
What is the Mitochondria?
This disease is caused by an increased Nucleus size
What is Cancer?
The percent of atomic mass of an atom that the Nucleus accounts for
What is 99.9%?
