Molecules & Variables
Explanation:
Ribosomes are composed of two subunits, the large and the small subunit, both of which consist of ribosomal RNA (rRNA) molecules and a variable number of ribosomal proteins. Several factor proteins catalyze different steps of protein synthesis by binding transiently to the ribosome.
~Hope this helps
The ribosome is a complex molecule made of ribosomal RNA molecules and proteins that form a factory for protein synthesis in cells.
