Example sentences for: spirotrichs
How can you use “spirotrichs” in a sentence? Here are some example sentences to help you improve your vocabulary:
Near the end of endo-replication in Spirotrichs many transposons and transposon-like sequences are eliminated by precise excision (Internal Eliminated Sequences or IESs [ 23 ] ). Excision directly precedes massive chromatid fragmentation and de novo telomere formation ("chromosome healing" [ 9 ] ) and the degradation of IESs and of "spacer" DNAs that lie between blocks of sequences destined for different MAC chromosomes.
These processes have been best studied in Tetrahymena thermophila and in various Spirotrichs, including Euplotes crassus . Breakage occurs at ~200 "cut" sites in Tetrahymena , and at ~40,000 sites in Spirotrichs.
Therefore, the latter two chromosomes each carry two genes [ 25 ] , a novel finding in Spirotrichs (see [ 24 ] ). The identities of the genes have not suggested any selective advantage to such couplings, but the alternative processing of this locus has been conserved within the Oxytrichs, and with variation, in some Stylonychids (A.
The ploidy can reach ~64 in some Spirotrichs [ 21 22 ] . Thus, each sequence that survives subsequent elimination (MAC-destined) is represented by numerous polytene chromatids; in principle, each could be processed differently.
The Oxytricha MAC genome is typical of those of other Spirotrichs.
