Zitat des Tages über Mutationen / Mutations:
Freedom comes only to those who no longer ask of life that it shall yield them any of those personal goods that are subject to the mutations of time.
I suspect any worries about genetic engineering may be unnecessary. Genetic mutations have always happened naturally, anyway.
The function of literature, through all its mutations, has been to make us aware of the particularity of selves, and the high authority of the self in its quarrel with its society and its culture. Literature is in that sense subversive.
You would think that UV just causes mutations, but it doesn't; you need a gene to be active for it.
A final proof of our ideas can only be obtained by detailed studies on the alterations produced in the amino acid sequence of a protein by mutations of the type discussed here.
Language thus becomes monumental because of the mutations of advertising.
Just like mutations to DNA in biological organisms allow for evolution through natural selection, forking lets us run multiple experiments in parallel where the strongest versions survive.
This seems highly likely, especially as it has been shown that in several systems mutations affecting the same amino acid are extremely near together on the genetic map.
Things look especially bleak for common killers such as diabetes and heart disease. Those ailments clearly have a genetic component. But when scientists survey genes looking for which mutations patients have in common, they come up empty.
If we didn't have genetic mutations, we wouldn't have us. You need error to open the door to the adjacent possible.
Most mutations involve typos: Something bumps a cell's elbow as it's copying DNA, and the wrong letter appears in a triplet - CAG becomes CCG.
Life has survived for more than three billion years because it is robust, and almost no mutations can easily outwit the defense mechanisms built up through eons of exposure to potential pathogens.
Our experience in fooling around with the genes of mice has taught us that many of the traits that interest us are not definite products of specific mutations but emergent phenomena arising from extremely complex interactions between genes, environment, and life experience.
In agriculture, people have taken wild plants that can't be eaten by people - and turned them into wonderful food sources. And that's because genomes can change, and people working with plants have picked mutations. Mutations are nothing more than genetic changes.
I was taught over and over again that the accumulation of random mutations led to evolutionary change - led to new species. I believed it until I looked for evidence.
First of all, many human diseases are influenced by, if not caused by mutations in genes.
Although not yet routine, many cancer centers have the technology to sequence some or all of a patient's cancer genome. This can provide massive amounts of valuable information about your cancer, including whether you have genetic mutations and other abnormalities for which new drugs are available.
Bacteria evolve, and so they become resistant to existing drugs. Sometimes they revert, depending on how damaging the mutation is to the life cycle of the bacteria. Mutations that give rise to resistance against particular compounds do increase, and that is why you constantly have to have new ones.
