WebbThere are 7 important functions of Ribosomes in the cell. These are mentioned below: 1. Ribosomes bring together mRNA and tRNAs to catalyze protein synthesis 2. Ribosomes are required for the growth of the cell 3. Free Ribosomes located in the cytoplasm create proteins that can be used within the cell 4. WebbThe information to produce a protein is encoded in the cell’s DNA. When a protein is produced, a copy of the DNA is made (called mRNA) and this copy is transported to a ribosome. Ribosomes read the information in the mRNA and use that information to assemble amino acids into a protein. If the protein is going to be used within the …
