Ageing Research Reviews
|November 23, 2013
Summary
This study proposes an RNA population model as a genetic theory of aging. It explains aging, differentiation, and tumorigenesis by highlighting the role of repetitive DNA sequences in gene activation.
Area of Science:
- Genetics
- Molecular Biology
- Gerontology
Background:
- Aging is a universal biological process in multicellular eukaryotes.
- Current aging theories lack universal acceptance.
- The RNA population gene activating model (Lv et al., 2003) provides a framework for understanding gene regulation.
Purpose of the Study:
- To refine the existing RNA population gene activating model.
- To propose a novel genetic theory of aging based on RNA populations.
- To explore the model's applicability to differentiation and tumorigenesis.
Main Methods:
- Literature review of existing reports on aging mechanisms.
- Integration of recent research findings.
- Analysis of the role of repetitive DNA sequences in gene activation.
Main Results:
- The refined RNA population model is presented as a genetic theory of aging.
- Evidence supports the role of repetitive sequences in gene activation.
- The model potentially explains the biological significance of non-coding DNA/RNA and repetitive sequences.
Conclusions:
- The RNA population model offers a unified genetic explanation for aging.
- The model provides insights into differentiation and tumorigenesis.
- Predictions regarding aging and differentiation phenomena are derived from the model.

01:25What is Population Genetics?
64.9K
A population is composed of members of the same species that simultaneously live and interact in the same area. When individuals in a population breed, they pass down their genes to their offspring. Many of these genes are polymorphic, meaning that they occur in multiple variants. Such variations of a gene are referred to as alleles. The collective set of all the alleles within a population is known as the gene pool.

02:35Band Theory
17.3K
When two or more atoms come together to form a molecule, their atomic orbitals combine and molecular orbitals of distinct energies result. In a solid, there are a large number of atoms, and therefore a large number of atomic orbitals that may be combined into molecular orbitals. These groups of molecular orbitals are so closely placed together to form continuous regions of energies, known as the bands.
The energy difference between these bands is known as the band gap.

02:04Conservation of Small Populations
17.4K
Small population sizes put a species at extreme risk of extinction due to a lack of variation, and a consequent decrease in adaptability. This weakens the chances of survival under pressures such as climate change, competition from other species, or new diseases. Large populations are more likely to survive pressures such as these, as such populations are more likely to harbor individuals that have genetic variants that are adaptive under new stresses. Small populations are much less...

01:39Chromosomal Theory of Inheritance
60.4K
In 1866, Gregor Mendel published the results of his pea plant breeding experiments, providing evidence for predictable patterns in the inheritance of physical characteristics. The significance of his findings was not immediately recognized. In fact, the existence of genes was unknown at the time. Mendel referred to hereditary units as “factors.”
