how does ribosomes work without proteins ? 


Expert Answer

Step 1

A ribosome is a complex structure with two subunits (large and small) that plays an important role in synthesizing the proteins (from mRNA transcribed from DNA) required by a cell. Ribosomes are made up of r-RNA and proteins that together forms the assembly of a ribosome and perform its function.

Step 2

Ribosomes may be found on the surface of rough endoplasmic reticulum or free in the cytoplasm of a cell. Despite different location in a cell, the function and structure of bound and free ribosomes are quite alike. A ribosome is composed of approximately 37-62% RNA (vary with different organisms and type of ...
