Sentences with phrase «contains ribosome»

The exact function of the toxin in the iris flower is still unknown, but scientists believe it contains ribosome inactivating proteins (RIPs) that interfere with RNA and protein synthesis.

Despite all these novel properties, Pandoraviruses display the essential characteristics of other viruses in that they contain no ribosome, produce no energy and do not divide.

Not exact matches

Ribosomes, the cellular factories that manufacture proteins, contain both RNA and protein, but exactly how all of the different ribosomal components contribute to protein synthesis is still not clear.

Some mRNAs also contain introns, extra sequences that do not encode protein and must be spliced out before they journey to the ribosome.
