CRISPR

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...

Genome Copying Errors02:46

Genome Copying Errors

5.5K
DNA replication is a well-evolved process that copies millions of base pairs with high fidelity during each cell division. Occasionally a wrong base or a long stretch of wrong bases may get added to the daughter strands. If the errors are left unchecked, cells might accumulate several mutations that might endanger their  survival. Therefore, the copying errors are checked and repaired at three levels.

Mismatch Repair01:20

Mismatch Repair

7.0K
Organisms are capable of detecting and fixing nucleotide mismatches that occur during DNA replication. This sophisticated process requires identifying the new strand and replacing the erroneous bases with correct nucleotides. Mismatch repair is coordinated by many proteins in both prokaryotes and eukaryotes.
The Mutator Protein Family Plays a Key Role in DNA Mismatch Repair
The human genome has more than 3 billion base pairs of DNA per cell. Prior to cell division, that vast amount of genetic...

Genomic Imprinting and Inheritance

38.7K
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.
The expression of some genes depends on which parent passed the gene to the offspring, through a phenomenon known as...

Area of Science:

  • Human genetics
  • Biotechnology
  • Bioethics

Background:

  • Recent advancements in genetic technologies, including CRISPR/Cas9 and Mitochondrial Replacement Therapy (MRT), enable heritable human genome modifications.
  • These technologies have sparked public debate and apprehension regarding germline interventions.
  • Historical opposition to reproductive technologies like In Vitro Fertilization (IVF) and cloning, which proved beneficial and manageable, offers context for current concerns.

Purpose of the Study:

  • To address the public's fear and suspicion surrounding germline interventions.
  • To provide a historical perspective on the acceptance and regulation of novel reproductive technologies.
  • To argue for the continued research and development of CRISPR technology for potential human application.

Main Methods:

  • Review of historical public and scientific reactions to reproductive technologies.
  • Analysis of the ethical and safety considerations surrounding CRISPR/Cas9 and MRT.
  • Argumentative approach based on historical precedents and current scientific understanding.

Main Results:

  • Public hostility towards germline interventions mirrors past baseless fears surrounding IVF and cloning.
  • IVF and cloning have demonstrated significant benefits to humanity under effective regulation.
  • Current evidence does not suggest that human application of CRISPR technology would be inherently unsafe or unethical.

Conclusions:

  • CRISPR gene editing technology should be pursued through research until deemed safe for human use.
  • There is no inherent reason to assume that the future use of CRISPR in humans will be unsafe or unethical.
  • Learning from the history of IVF and cloning suggests that new reproductive technologies can be safely regulated and ethically applied.
