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 does a nucleus do in protein production and modification?
The nucleus is where DNA which codes for proteins is stored. The DNA is transcribed to make mRNA in the nucleus. The mRNA then leaves the nucleus where it is translated on the ribosomes into a series of amino acids which make up a protein. So the role of the nucleus is to tell the cell which proteins to make.
What organelle that manages or controls all the cell functions in a eukaryotic cell?
The nucleus is the organelle that manages and controls all cell functions in a eukaryotic cell. It contains the cell's genetic material and regulates gene expression, cell division, and protein synthesis.
What does the nucleolus in a cell organelle do?
The nucleolus is responsible for producing ribosomal RNA (rRNA) and assembling ribosomes, which are essential for protein synthesis in the cell. It is found inside the nucleus and plays a crucial role in protein production.

What organelle can be described as the blueprint to the creation of a protein?
The cell nucleus contains the "blueprints" for the production of protein. The "blueprints" are the DNA contained within the nucleus. DNA is often called the blueprint of life.
What is the function of the nucleus in plant and animal and animal cell?
The nucleus serves as the control center of both plant and animal cells, housing the cell's genetic material (DNA) and coordinating activities such as growth, metabolism, and reproduction. It regulates gene expression and mediates cellular responses to environmental signals. Additionally, the nucleus is involved in the synthesis of ribosomal RNA and the assembly of ribosomes, which are essential for protein production.

What word best describes the role of the nucleus?
The word that best describes the role of the nucleus is "control." The nucleus acts as the control center of the cell, where the genetic information is stored and regulates cell activities by controlling gene expression and directing protein synthesis.
What is a primary function of a nucleus?

How does nicotine affect the myelin production?
Nicotine stimulates CREB phosphorylation which regulates the expression of myelin basic protein and myelin oligodendrocyte glycoprotein.
What are the special features of a cell nucleus?
The nucleus of a cell contains the genetic material in the form of DNA, which regulates cell functions. It is surrounded by a double membrane called the nuclear envelope, which controls the movement of substances in and out of the nucleus. The nucleus also contains a nucleolus, which is involved in the production of ribosomes for 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.
