Eloge de la différence: La génétique et les hommes by Albert Jacquard

By Albert Jacquard

Les progrès de los angeles génétique ont généré autant de fantasmes démiurgiques que d'espoirs bien fondés. L'eugénisme est au nombre de ces utopies mortifères qu'entretient à son insu l. a. technology. Pourtant, l'imprévisible diversité des individus qui l. a. composent constitue los angeles caractéristique essentielle de l'espèce humaine, et le devenir de chaque être est par nature incertain. Cette contingence irréductible tient aux rapports qu'entretiennent en l'homme l'inné et l'acquis. L'un ne peut se définir sans l'autre : l'inné est l. a. faculté d'acquérir ; l'acquis est le développement indéterminé de cette faculté. Aussi, l. a. volonté d'expliquer l'histoire d'un individu par le déterminisme génétique est-elle vouée à l'échec.

Le chapitre où l'auteur démontre le caractère idéologique et non scientifique des checks destinés à révéler les déterminations génétiques de l'intelligence humaine est une vraie leçon de clairvoyance. los angeles lecture de ce passage - "Intelligence et génétique" - justifie à elle seule qu'on se procure cet ouvrage éclairé du plus philosophe des généticiens contemporains. --Paul Klein

Sample text

Mitosis then ensures that one chromatid from each replicated chromosome passes into each new cell. Another genetically important result of the cell cycle is that each of the cells produced contains a full complement of chromosomes—there is no net reduction or increase in chromosome number. Each cell also contains approximately half the cytoplasm and organelle content of the original parental cell, but no precise mechanism analogous to mitosis ensures that organelles are evenly divided. Consequently, not all cells resulting from the cell cycle are identical in their cytoplasmic content.

Cytokinesis Interphase: cell growth G0 G1/S checkpoint 3 After the G1/S checkpoint, the cell is committed to dividing. 7 The cell cycle consists of interphase and M phase. a cell has divided and produced two new cells. Each new cell metabolizes, grows, and develops. At the end of its cycle, the cell divides to produce two cells, which can then undergo additional cell cycles. Progression through the cell cycle is regulated at key transition points called checkpoints. The cell cycle consists of two major phases.

Because eukaryotes possess multiple chromosomes, mechanisms exist to ensure that each new cell receives one copy of each chromosome. Most eukaryotic cells are diploid, and their two chromosome sets can be arranged in homologous pairs. Haploid cells contain a single set of chromosomes. ✔ Concept Check 2 Diploid cells have a. two chromosomes. b. two sets of chromosomes. c. one set of chromosomes. d. two pairs of homologous chromosomes. Chromosome structure The chromosomes of eukaryotic cells are larger and more complex than those found in prokaryotes, but each unreplicated chromosome nevertheless consists of a single molecule of DNA.
