Ribosomes are necessary for
Webb29 okt. 2024 · Ribosomes are the organelles in a cell that are responsible for protein synthesis. Proteins are essential for many cellular functions, such as cell signaling, cell movement, and enzymatic activity. Without proteins, cells would not be able to carry out these important functions. WebbRibosomes are essential in the synthesis of proteins in all living organisms. The nucleotide sequence of the messenger ribonucleic acid (mRNA) is decoded by this cell organelle, which binds to the mRNA and decodes the information it contains.
