Animal Cell Ribosomes
Ribosomes are protein builders of the cell. They are found in many place in the cytoplasm. They might be seen freely float in gin 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 proteins ina 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 the mRNA molecule and hence the protein are synthesized.
