If transcription maintained chromosome structure, a transcription inhibitor would be expected to alter chromosome volume and morphology, leading to a more condensed state.
It will be of interest to understand if the oil palm has added nearly double the sequence to the genome while maintaining chromosome structure or the date palm has lost ancestral DNA.
This in turn renders oocytes innately susceptible to aneuploidy, which is made worse by an age-related reduction in key SAC regulators and factors that maintain chromosome and spindle structure (Jones and Lane, 2013; Sebestova et al., 2012).
Telomeres are nucleoprotein structures located at the ends of chromosomes that perform a capping function to maintain chromosome stability and integrity.
Telomeres are DNA-protein structures that define the ends of linear chromosomes and form a protective 'cap' that enables cells to maintain chromosome length and stability by preventing telomere degradation, recombination, and end-to-end fusions (reviewed in [1], [2]).
Telomeres form the ends of eukaryotic chromosomes and serve as protective caps that keep chromosomes structure independency and completeness.
Mammalian telomeres are specialized chromatin structures that require the telomere binding protein, TRF2, for maintaining chromosome stability.
The emerging evidences suggest that G4 DNA structures have crucial roles in a variety of biological processes, including transcription, recombination, replication, and maintaining chromosome stability.
Moreover, the fact that these strains have completely conserved gene orders suggests that they maintained an intact chromosome structure since the time of their separation.
Despite the fact that the oil palm genome is more than double the size (1.535 Gb) of the date palm genome (0.67 Gb), long-range synteny is maintained and overall chromosome structure is very well preserved.
