Q:

What are the three organelles involved in protein synthesis?

A:

There are four organelles that are involved in protein synthesis. These include the nucleus, ribosomes, the rough endoplasmic reticulum and the Golgi apparatus, or the Golgi complex. All four work together to synthesize, package and process proteins.

Protein synthesis begins with DNA. The DNA in an organism creates the RNA that then codes for and synthesizes the proteins. DNA is found in the cell’s nucleus and makes the RNA in the nucleus as well. The RNA then exits the nucleus and is translated by the cell’s organelles into amino acids. These small subunits are then put together in the ribosomes that are attached to the membrane of the rough endoplasmic reticulum. Then, the proteins exit the ribosomes and exit the rough endoplasmic reticulum to enter the Golgi apparatus. The Golgi apparatus packages the proteins and sends them out of the cell.

  • Q:

    What is a protein synthesis summary?

    A:

    Protein synthesis is a two-step process that individual cells undergo to manufacture proteins necessary to their survival. Specific enzymes within a cell's nucleus initiate protein synthesis by unwinding sections of deoxyribonucleic acid (DNA) for ribonucleic acids (RNA) to read, which then synthesizes a single strand of messenger RNA (mRNA) that leaves the nucleus and joins with ribosomes in the cytoplasm. Protein synthesis occurs through the formation of amino acids.

  • Q:

    What organelle is the site of protein synthesis?

    A:

    There are four organelles found in eukaryotic cells that aid in the synthesis of proteins. These organelles include the nucleus, the ribosomes, the rough endoplasmic reticulum and the Golgi apparatus. All of these organelles help produce and process proteins, but only the ribosomes actually piece together amino acids into proteins.

  • Q:

    How does the nucleus control protein synthesis in cytoplasm?

    A:

    The nucleus controls protein synthesis in a cell's cytoplasm in the sense that the genetic codes contained in the nucleus determine the sequence of amino acids that are assembled to build the proteins. This is the only aspect of protein assembly directly controlled by the nucleus, while other mechanisms and structures in the cell are responsible for detecting which proteins are needed. The nucleus serves as a protein code database.

    What are unattached ribosomes in the cytosol?

    A:

    Unattached ribosomes, also known as free ribosomes, are described by Seattlepi as intracellular bodies that initiate protein synthesis by translating messenger RNA. These bodies float freely in the cytosol. The mRNA that is translated by the unattached ribosomes stays in the cytosol.
