Definition of polysome in English: polysomenoun ˈpɒlɪsəʊmˈpälēˌsōm Biology A cluster of ribosomes held together by a strand of messenger RNA which each is translating. Example sentencesExamples - This loss of protein synthetic capacity is manifested in a loss of polysomes that result from the run-off of ribosomes from mRNAs coupled with a failure in the initiation machinery.
- The peaks of free 40S and 60S subunits, 80S ribosomes (free couples and monosomes), and polysomes are indicated.
- The rest are nuclear-encoded and are synthesized as precursor proteins on free cytosolic polysomes.
- This value was lower than the average amount of mRNA detected in all polysomes (two ribosomes per mRNA) in leaves of arabidopsis and rapidly dividing yeast cells.
- Anoxia causes polysomes, translating the aerobic proteins, to dissociate, and anaerobic mRNAs are translated from polysomes with a much lower average size.
