produce proteins by following coded instructions that came from the nucleus.
Proteins are made by ribosomes in the cytoplasm and can be attached to the endoplasmic reticulum for further processing and sorting. This attachment occurs when the ribosome translates a signal sequence on the protein that directs it to the endoplasmic reticulum for insertion.
Ribosomal RNA, rRNA, forms part of the ribosme. Transport RNA, tRNA, transports a specific amino acid to the ribosome. Messenger RNA, mRNA, carries the codon, message, from the DNA in the nucleus to the cytoplasm.
