Ribosomes (/ ˈraɪbəzoʊm, - soʊm /) are macromolecular machines, found within all cells, that perform biological protein synthesis (messenger RNA translation). Ribosomes link amino acids together in the order specified by the codons of messenger RNA molecules to …

2025年3月1日 · ribosome, particle that is present in large numbers in all living cells and serves as the site of protein synthesis. Ribosomes occur both as free particles in prokaryotic and eukaryotic cells and as particles attached to the membranes of the endoplasmic reticulum in eukaryotic cells.

2017年4月28日 · A ribosome is a complex cellular mechanism used to translate genetic code into chains of amino acids. Long chains of amino acids fold and function as proteins in cells. The function of a ribosome in any cell is to produce proteins.

2025年1月25日 · Ribosomes are macromolecular machines found in all living cells that synthesize proteins by translating messenger RNA (mRNA). Located in the cytoplasm, ribosomes either float freely or attach to the endoplasmic reticulum in eukaryotic cells.

3 天之前 · A ribosome is the cellular machinery responsible for making proteins. There are many ribosomes in each cell, each made up of two subunits. These two subunits lock around the messenger RNA and then travel along the length of the messenger RNA molecule reading each three-letter codon.

A ribosome is a complex molecular machine found inside the living cells that produce proteins from amino acids during a process called protein synthesis or translation. The process of protein synthesis is a primary function, which is performed by all living cells.

2021年8月24日 · Ribosomes are cell structures present in large numbers in all living cells acting as the site of protein synthesis. In prokaryotes, they float freely in the cytoplasm, while in eukaryotes they are free or remain bound to the outer membrane of the endoplasmic reticulum. They are also found in the mitochondria and chloroplast of a eukaryotic cell.

2023年11月5日 · The ribosome is a complex molecular machine, found within all living cells, that serves as the site of biological protein synthesis (translation). Ribosomes link amino acids together in the order specified by messenger RNA (mRNA) molecules.

The ribosome is a complex molecule made of ribosomal RNA molecules and proteins that form a factory for protein synthesis in cells. In 1955, George E. Palade discovered ribosomes and described...

2024年4月9日 · A ribosome is a cellular structure that assembles proteins by linking together amino acids based on genetic instructions from messenger RNA (mRNA). What are Ribosomes? Ribosomes were first observed by George Palade (1953) under the electron microscope.
