What organelle contains a nucleolus?

What organelle contains a nucleolus?

The nucleolus is a region found within the cell nucleus that is concerned with producing and assembling the cell’s ribosomes. Following assembly, ribosomes are transported to the cell cytoplasm where they serve as the sites for protein synthesis.

Which organelle is the control center of the cell nucleus?

nucleus
The organelle that is the control center for the cell is the nucleus. The nucleus is a sphere in the center of the cell that holds DNA.

What organelles is the control center?

Known as the cell’s “command center,” the nucleus is a large organelle that stores the cell’s DNA (deoxyribonucleic acid). The nucleus controls all of the cell’s activities, such as growth and metabolism, using the DNA’s genetic information.

Is the nucleolus the control center of the cell?

Nucleus is separated from the rest of the cell or the cytoplasm by a nuclear membrane. As the nucleus regulates the integrity of genes and gene expression, it is also referred to as the control center of a cell. The structure of a nucleus encompasses nuclear membrane, nucleoplasm, chromosomes and nucleolus.

What is found in the nucleolus?

The nucleolus is the site of transcription and processing of rRNA and of assembly of preribosomal subunits. Thus it consists of ribosomal DNA, RNA, and ribosomal proteins, including RNA polymerases, imported from the cytosol.

What other organelle is assembled in the nucleolus?

ribosomes
Large and small ribosomes are fully assembled in the nucleolus, and are then exported to the cytoplasm. The RNA and protein components of the enzyme telomerase are also assembled in the nucleolus.

Which organelle is the control center of the cell quizlet?

The Nucleus: The Control Center of the Cell.

What eukaryotic organelle contains chromatin and a nucleolus?

Eukaryotic Nucleus
Eukaryotic Nucleus: The nucleus stores chromatin (DNA plus proteins) in a gel-like substance called the nucleoplasm. The nucleolus is a condensed region of chromatin where ribosome synthesis occurs.

What function does the nucleolus have?

The nucleolus is the most conspicuous domain in the eukaryotic cell nucleus, whose main function is ribosomal RNA (rRNA) synthesis and ribosome biogenesis.

Is the nucleolus an organelle?

The nucleolus is not technically an organelle, but it is a structure within the nucleus. The nucleolus’ function is to produce ribosomes, the tiny factories that assemble proteins within the cell. No it is not. Because as organelles are present in cytoplasm and considered it’s part.

Which organelle is the control center of the cell?

Nucleus The nucleus is the control center for the cell. The nucleolus is found in the nucleus. The nuclear envelope is located outside the nucleus. The Chromosomes and chromatin are both located in the nucleus. Ribosomes are small organelles that make protiens.

Where is the nucleus located in the cell?

The nucleus is found in the center of the cell with a membrane around it. The membrane has pores on it so RNA can travel out and tell the organelles what to do. Also it keeps chromosomes protected within the membrane.

How to study the arrangement of the nucleolus within the cell?

The arrangement of the nucleolus within the cell can be clearly studied by the techniques – fluorescent recovery after photobleaching and fluorescent protein tagging. The nucleolus of several plant species has very high concentrations of iron in contrast to the human and animal cell nucleolus.
