Replication in Eukaryotes

19.1K
In eukaryotic cells, DNA replication is highly conserved and tightly regulated. Multiple linear chromosomes must be duplicated with high fidelity before cell division, so there are many proteins that fulfill specialized roles in the replication process. Replication occurs in three phases: initiation, elongation, and termination, and ends with two complete sets of chromosomes in the nucleus.

Replicative Cell Senescence

4.6K
Replicative cell senescence is a property of cells that allows them to divide a finite number of times throughout the organism's lifespan while preventing excessive proliferation. Replicative senescence is associated with the gradual loss of the telomere — short, repetitive DNA sequences found at the end of the chromosomes. Telomeres are bound by a group of proteins to form a protective cap on the ends of chromosomes. Embryonic stem cells express telomerase — an enzyme that adds...

Telomeres and Telomerase

28.7K
In eukaryotic DNA replication, a single-stranded DNA fragment remains at the end of a chromosome after the removal of the final primer. This section of DNA cannot be replicated in the same manner as the rest of the strand because there is no 3’ end to which the newly synthesized DNA can attach. This non-replicated fragment results in gradual loss of the chromosomal DNA during each cell duplication. Additionally, it can induce a DNA damage response by enzymes that recognize single-stranded...

Area of Science:

  • Genomics
  • Molecular Biology
  • Epigenetics

Background:

  • Historically, the human genome was viewed as static.
  • Recent research indicates genomic plasticity throughout an individual's life.

Purpose of the Study:

  • To examine the concept of a genome with a lifespan.
  • To explore the role of chromatin biology in genomic changes.
  • To analyze how time and experience are embodied in chromatin.

Main Methods:

  • Review of current literature on genome dynamics.
  • Analysis of chromatin biology advancements.
  • Case study examples of life course and chromatin changes.

Main Results:

  • The genome is mutable, influenced by development, aging, disease, and environment.
  • Chromatin biology provides a mechanism for the genome to embody experience.
  • Time-dependent changes in chromatin reflect life events.

Conclusions:

  • A dynamic, lifespan genome integrates molecular and experiential aspects of life.
  • This perspective shifts understanding of life stages and health/disease temporality.
