what part of the cell synthesizes proteins
This genetic information is found in the nucleus, though protein synthesis actually occurs in ribosomes found in the cytoplasm and on rough endoplasmic reticulum. If protein is to be synthesised, then the genetic information in the nucleus must be transferred to these ribosomes. This is done by mRNA (messenger ribonucleic acid). It is very similar to DNA, but fundamentally differs in two ways. 1  A base called uracil replaces all thymine bases in mRNA.
