¿Patentes sobre fragmentos de ADN complementarios y aleatorios?
Resumen
La propuesta de los Institutos Nacionales de la Salud (NIH) para patentar secuencias del genoma humano es legalmente defectuosa y obstaculiza la investigación en biotecnología. Controlar el material genético crudo antes de que se demuestre su utilidad impide el progreso científico.
Área de la Ciencia:
- Derecho de la biotecnología Derecho de la biotecnología.
- Propiedad intelectual La propiedad intelectual.
- Investigación genómica de la investigación genómica.
Sus antecedentes:
- Los Institutos Nacionales de la Salud (NIH) propusieron patentar productos derivados únicamente de la secuenciación del genoma humano.
- Esta propuesta plantea importantes cuestiones legales y éticas con respecto a la propiedad intelectual en la biotecnología.
- El control de las materias primas científicas antes de que se establezcan sus aplicaciones prácticas es una preocupación creciente.
Objetivo del estudio:
- Analizar las implicaciones legales y éticas de patentar secuencias del genoma humano.
- Criticar la propuesta de los NIH basada en la ley de patentes existente, específicamente el requisito de "utilidad".
- Proponer soluciones para abordar el problema más amplio del control de los descubrimientos científicos fundamentales.
Principales métodos:
- Análisis jurídico de la ley de patentes con respecto a la "utilidad" y los "productos de la naturaleza".
- Examen de la propuesta del NIH y su impacto potencial en la innovación biotecnológica.
- Revisión de los marcos jurídicos existentes y recomendaciones de políticas.
Principales resultados:
- La propuesta de los NIH se considera legalmente cuestionable, y potencialmente viola los requisitos de la ley de patentes.
- La patentación de datos genómicos crudos antes de que se determine su utilidad práctica sofoca la experimentación científica y la innovación.
- El sistema legal actual puede estar mal equipado para manejar la patentación de descubrimientos biotecnológicos fundamentales.
Conclusiones:
- La propuesta de los NIH para patentar secuencias del genoma humano es poco aconsejable y legalmente poco sólida.
- Se necesita una reevaluación más amplia de la ley de patentes para abordar el control de las materias primas científicas en la biotecnología.
- Se proporcionan recomendaciones para el Poder Ejecutivo, el Congreso y los tribunales para rectificar estos problemas.

Homologous Recombination
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...
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...
Conservative Site-specific Recombination and Phase Variation
Because the DNA segments are cut and reorganized in a direction-specific manner, site-specific recombination has emerged as an efficient genetic engineering technique. Flippase and Cyclization recombinases or Flp and Cre, respectively, are two members of the tyrosine recombinase family derived from bacteriophages, that are used to mediate site-specific DNA insertions, deletions, and targeted expression of proteins in mammalian cell lines.
The recognition sites for Cre recombinase called LoxP...

Genome Copying Errors
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.
Gene Duplication and Divergence
The seminal work of Ohno in 1970 popularized the idea of gene duplication and divergence. DNA sequence comparison studies reveal that a large portion of the genes in bacteria, archaebacteria, and eukaryotes was generated by gene duplication and divergence, indicating its critical role in evolution.
The duplicated copies of the gene are called Paralogs. Paralogs with similar sequences and functions form a gene family. Across several species, a large number of gene families are characterized.

Restriction Enzymes
Restriction enzymes are bacterial enzymes used to cut DNA in a sequence-specific manner. To cleave DNA, they bind to specific palindromic sequences called restriction sites. Such palindromic DNA sequences or inverted repeats are commonly found in regions of functional significance, such as the origin of replication, gene operator sites, and regions containing transcription termination signals.
