Summary
Stem cells may retain template DNA strands during cell division, a concept known as immortal DNA strands, to prevent mutation accumulation. This review explores the evidence and epigenetic links to this DNA segregation phenomenon.
Area of Science:
- Molecular Biology
- Genetics
- Epigenetics
Context:
- DNA replication is prone to errors, potentially leading to mutations and cancer.
- The immortal DNA strand hypothesis proposes stem cells retain template DNA to minimize mutations.
Purpose:
- To review the evidence supporting the immortal DNA strand hypothesis.
- To explore the potential link between DNA strand segregation and epigenetic regulation.
- To discuss implications and underlying mechanisms of template DNA segregation.
Summary:
- This review examines the immortal DNA strand hypothesis, suggesting stem cells retain template DNA strands during mitosis to avoid accumulating replication errors.
- It explores experimental evidence and discusses how epigenetic modifications might influence this DNA segregation process.
- The potential role of epigenetics in governing cell states, self-renewal, and differentiation in relation to DNA strand inheritance is considered.
Impact:
- Provides insights into mechanisms preventing genomic instability and carcinogenesis.
- Highlights the interplay between DNA replication, strand segregation, and epigenetic regulation in stem cell biology.
- Offers a framework for understanding how cells maintain genomic integrity over time.

03:17Inheritance of Chromatin Structures
Epigenetics is the study of inherited changes in a cell's phenotype without changing the DNA sequences. It provides a form of memory for the differential gene expression pattern to maintain cell lineage, position-effect variegation, dosage compensation, and maintenance of chromatin structures such as telomeres and centromeres. For example, the structure and location of the centromere on chromosomes are epigenetically inherited. Its functionality is not dictated or ensured by the underlying DNA...
02:30Genomic Imprinting and Inheritance
Diploid organisms inherit genetic material through chromosomes from both parents. Copies of the same gene are known as alleles. In most cases, both alleles are simultaneously expressed and allow various cellular processes to function optimally. If one of the alleles is missing or mutated, the expression of the other allele can compensate; however, this is not true for all genes.

01:29Replication in Eukaryotes
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.

01:37Epigenetic Regulation
Epigenetic changes alter the physical structure of the DNA without changing the genetic sequence and often regulate whether genes are turned on or off. This regulation ensures that each cell produces only proteins necessary for its function. For example, proteins that promote bone growth are not produced in muscle cells. Epigenetic mechanisms play an essential role in healthy development. Conversely, precisely regulated epigenetic mechanisms are disrupted in diseases like cancer.
