In-vitro Mutagenesis

13.8K
To learn more about the function of a gene, researchers can observe what happens when the gene is inactivated or “knocked out,” by creating genetically engineered knockout animals. Knockout mice have been particularly useful as models for human diseases such as cancer, Parkinson’s disease, and diabetes.

Other than maintaining genome stability via DNA repair, homologous recombination plays an important role in diversifying the genome. In fact, the recombination of sequences forms the molecular basis of genomic evolution. Random and non-random permutations of genomic sequences create a library of new amalgamated sequences. These newly formed genomes can determine the fitness and survival of cells. In bacteria, homologous and non-homologous types of recombination lead to the evolution of new...

Homologous Recombination

50.2K
The basic reaction of homologous recombination (HR) involves two chromatids that contain DNA sequences sharing a significant stretch of identity. One of these sequences uses a strand from another as a template to synthesize DNA in an enzyme-catalyzed reaction. The final product is a novel amalgamation of the two substrates. To ensure an accurate recombination of sequences, HR is restricted to the S and G2 phases of the cell cycle. At these stages, the DNA has been replicated already and the...

CRISPR

49.5K
Genome editing technologies allow scientists to modify an organism’s DNA via the addition, removal, or rearrangement of genetic material at specific genomic locations. These types of techniques could potentially be used to cure genetic disorders such as hemophilia and sickle cell anemia. One popular and widely used DNA-editing research tool that could lead to safe and effective cures for genetic disorders is the CRISPR-Cas9 system. CRISPR-Cas9 stands for Clustered Regularly Interspaced...

Genetic Screens02:46

Genetic Screens

4.9K
Genetic screens are tools used to identify genes and mutations responsible for phenotypes of interest. Genetic screens help identify individuals or a group of people at risk of developing  genetic diseases and help them with early intervention, targeted therapy, and reproductive options.
Forward genetic screens
Forward or “classical” genetic screens involve creating random mutations in an organism’s DNA using radiation, mutagens, or insertion of additional bases, which...

Area of Science:

  • Conservation Biology
  • Genomics
  • Population Genetics

Background:

  • Inbreeding depression poses a significant threat to small, isolated populations.
  • Genetic rescue is a conservation strategy aimed at mitigating inbreeding depression.
  • Translocation, the movement of individuals between populations, is a potential tool for genetic rescue but carries inherent risks.

Purpose of the Study:

  • To evaluate the effectiveness and risks of translocation as a genetic rescue strategy.
  • To utilize genomic data for assessing translocation outcomes in the montane red fox.
  • To provide insights applicable to the conservation of other threatened species.

Main Methods:

  • Analysis of genomic data from montane red fox populations.
  • Assessment of genetic diversity and population structure.
  • Modeling potential outcomes of translocation events.

Main Results:

  • Genomic data provided a detailed evaluation of translocation as a conservation action.
  • The study identified key genetic considerations for successful translocations.
  • Findings have broader implications for managing genetic diversity in threatened species.

Conclusions:

  • Translocation can be a viable tool for genetic rescue when carefully planned and evaluated.
  • Genomic data are crucial for assessing the risks and benefits of conservation interventions.
  • The study offers a framework for applying genetic rescue strategies to other endangered populations.
