Centromere positions hg19

Thank you Giovanni, I applied the same filters but I have half of the centromeric regions. even the table Jeremy proposed in this page How can I get the human chromosome centromere position and chromosome length in GRCh37hg19 has half of the region.Normally a chromosome has just one centromere, but in chromosome 2 there are remnants of a second centromere in the q21. 3q22. 1 region. The presence of vestigial telomeres. These are normally found only at the ends of a chromosome, but in chromosome 2 there are additional telomere sequences in the q13 band, far from either end of the chromosome. centromere positions hg19

The centromere is the specialized DNA sequence of a chromosome that links a pair of sister chromatids. During mitosis, spindle fibers attach to the centromere via the kinetochore. Centromeres were first thought to be genetic loci that direct the behavior of chromosomes. The physical role of the centromere is to act as the site of assembly of the kinetochores a highly complex multiprotein structure that is

Centromere base positions from the GRCh36hg18, GRCh37hg19 and GRCh38hg38 genome builds.

Centromeres, the sites of spindle attachment during mitosis and meiosis, are located in specific positions in the human genome, normally coincident with diverse subsets of alpha satellite DNA. While there is strong evidence supporting the association of some subfamilies of alpha satellite with

Regarding question 2, centromeric and telomeric regions are hard masked in hg19, so there's no sequence to repeat mask. For hg38, the centromeres are labeled ALRAlpha with a class of centr. Telomeres are still hardmasked, but they tend to have simple repeats next to them (as annotated by repeatmasker, which makes sense).
