The ends of linear eukaryotic chromosomes — telomeres — consist of a specialized structure composed of a repetitive DNA sequence. Subtelomeric DNA, an operationally defined region adjacent to ...

Children with pediatric-onset multiple sclerosis (POMS) have shorter telomeres, suggesting MS may accelerate biological aging.

One such mechanism involves Alu elements, repetitive DNA sequences unique to primates, which can introduce variability by ...

Donald Coffey, a longtime professor at Johns Hopkins University, discovered the nuclear matrix within cells and its role in DNA replication. Telomeres are repetitive, noncoding sequences that cap the ...

Genome sequencing examines the entire genome ... This is especially true for very long repetitive sections of DNA (repeats) and for pieces of DNA that have been deleted, inserted, or rearranged ...
