Effects of chemicals on the germ lines of male mice were tested in a study designed to replicate pesticide use.
Germ line epigenetic modification of the murine Avy allele by nutritional supplementation.
In the poem titled "There are no words for us" she writes: "There is no language // genome, germ lines
, genomics / that captures / the rupture and joy / of gene-pool crossings // a channel as wide / as humankind.
They begin with basic stem cell biology, describing the derivation, properties and therapeutic implications of embryonic stem cells, and those procured from germ lines
and umbilical cords.
Further, three different labs have presented evidence that an ASC can be "teased" into all three germ lines
that make up all the cells of the human body.
The Darwinian explanation begins with the observation from nature that germ lines do not live forever.
Because of their common ancestry, the DNAs of the germ lines of any two living species will share some stretches of DNA that were present in their last common ancestor species.
The mindless sprouting of new germ lines from old from then until now, means that at the deepest chemical level of analysis, all life from its beginnings until now, has been DNA's way of making more DNA.
The genetic endowment of individuals, as well as the germ lines
from which they emerge, are among the natural resources of the earth, and possession of a child endowed with good genes should obligate his parents to compensate others for their possession of him as of other natural resources by payment into a global common fund.
To begin with, he argues that the increasing use of somatic therapy is only likely to increase the number of survivors with defective genes in their germ lines, who will pass an increasing number of genetic problems onto succeeding generations.
The prospect of creating a new eugenic man and woman is becoming ever more likely as a result of the steady advances in somatic and germ line genetic engineering technology.
