Animal cell ribosome
Ribosome are protein builders of the cell. They are found in many place in the cytoplasm. They might be seen freely floating in the cytoplasm and they are seen attached to the endoplasmic reticulum. Ribosomes of animal cells are also made of two subunits large (60s) and small (40s). When there is need for protein in a cell, the mRNA is produced in the nucleus and is sent to the cell and the ribosomes. The two subunits of the ribosomes come together at the time of protein formation and combine with mRNA molecule and hence the protein are sythesized
