What is Genetic Engineering?

Animal Mitochondrial Genetics

Animal Mitochondrial Genetics

Among all the organelles in an animal cell, only mitochondria have their own independent genomes. Animal mitochondrial DNA is a double-stranded, closed-circular molecule with around 20,000 base pairs. Mitochondrial DNA is unique in that one of its two strands, the heavy, or H, -strand is guanine rich, whereas the complementary strand is cytosine rich and called the light, or L, -strand. Compared to nuclear DNA, mitochondrial DNA has a very low percentage of non-coding regions and is marked by...

In-vitro Mutagenesis

In-vitro Mutagenesis

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.

Gene Conversion

Gene Conversion

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...

Mismatch Repair

Mismatch Repair

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...

Area of Science:

Genetics
Bioethics
Reproductive Medicine

Background:

Mitochondrial diseases are inherited genetic disorders with limited treatment options.
Mitochondrial (mtDNA) replacement techniques offer a potential cure by replacing faulty mitochondria.
The UK legalized mtDNA replacement in 2015, but global adoption remains slow due to ethical concerns.

Purpose of the Study:

To analyze the ethical challenges associated with mtDNA replacement techniques.
To explore the ethical principles supporting the adoption of mtDNA replacement.
To propose policy recommendations for the US to permit mtDNA replacement.

Main Methods:

Review of current mitochondrial disease treatments and replacement therapies.
Analysis of ethical considerations including safety, efficacy, and three-parent genetics.
Examination of ethical principles: beneficence, nonmaleficence, autonomy, and justice.

Main Results:

Ethical challenges exist regarding safety, efficacy, and genetic material contribution.
Ethical principles support the use of mtDNA replacement therapies.
The UK's policy provides a model for US regulatory changes.

Conclusions:

Addressing ethical challenges is essential for implementing mtDNA replacement in the US.
Policy changes, similar to the UK's, can facilitate patient access to treatment.
Overcoming barriers is vital given the prevalence and severity of mitochondrial diseases.
