what is the function of the ribosomes
Answers
Answer:
Ribosomes have two main functions — decoding the message and the formation of peptide bonds. These two activities reside in two large ribonucleoprotein particles (RNPs) of unequal size, the ribosomal subunits. Each subunit is made of one or more ribosomal RNAs (rRNAs) and many ribosomal proteins (r-proteins).
Ribosomes are non-membrane-bounded particles where protein synthesis occurs. The number of ribosomes in a cell varies depending on its functions. For example, pancreatic cells and those of other glands have many ribosomes because they produce secretions that contain proteins.
Though, simply, they are:
- tiny dot-like structures
- composed of RNA and protein
- they have two types; attached (to the rough ER) and free
- they function for protein synthesis
