Sentences with phrase «chromosomes during the replication»

Telomeres provide protection to chromosomes during the replication process to prevent the loss of DNA strands.

Not exact matches

Telomeres are repetitive stretches of DNA that cap natural chromosome ends to protect them from being damaged or fused together during DNA replication.

This group also clarified that Shugoshin controls DNA replication (the process by which DNA makes a copy of itself during cell division) in subtelomeres as well as higher - order structure of chromosomes.

The dance of chromosomes is tightly controlled during cell replication to preserve the genetic makeup of cells.

During meiosis, the genome of a diploid germ cell, which is composed of long segments of DNA packaged into chromosomes, undergoes DNA replication followed by two rounds of division, resulting in haploid cells called gametes.

The shortening of telomeres is a process that occurs naturally in the body each time that a cell divides: during cell division the DNA, which is tightly packaged into chromosomes, must be duplicated but the DNA - copying machinery design itself, prevents the full replication of the ends of the chromosomes.

Telomeres are repetitive nucleotide sequences found at the end of chromosomes which protect them from deteriorating during the process of replication.

Partly based on his MIT Ph.D. thesis research performed in yeast, Sheltzer suspects aneuploidy causes errors in DNA replication, as well as problems with chromosome segregation during cell division.

That poses an obvious problem during S phase: While DNA replication machineries («replisomes») zip along the chromosomes trying to faithfully duplicate the entire genome in a matter of just a couple of hours, they encounter — on average — multiple cohesin rings that are already wrapped around DNA.
