Interstitial telomeric sequences in vertebrate chromosomes: Origin, function, instability and evolution
(Elsevier Science, 2017-07)
By definition, telomeric sequences are located at the very ends or terminal regions of chromosomes. However, several vertebrate species show blocks of (TTAGGG)n repeats present in non-terminal regions of chromosomes, the ...
Chromosome number in Halophytum ameghinoi (Halophytaceae)
(Springer Wien, 2000-12)
The chromosome number and karyotype of Halophytum ameghinoi (Speg.) Speg. was found to be 2n = 24 and 12 m+ 10 sm+ 2t, respectively. Meiosis was regular and 12 bivalents were observed. The relationships of this monotypic ...
