Macronuclear Subunits of Tetrahymena thermophila Are Functionally Haploid.

In Tetrahymena thermophila the major argument for the existence of diploid subunits has been that some loci show a delay in the accumulation of stable subclones during macronuclear assortment. This delay is based on the assumption that throughout the life cycle there are 45 subunits. We find that for at least 50 fissions after conjugation there is… CONTINUE READING
