Genetic Transmission Quotes

It is raining DNA outside. On the bank of the Oxford canal at the bottom of my garden is a large willow tree, and it is pumping downy seeds into the air. ... spreading DNA whose coded characters spell out specific instructions for building willow trees that will shed a new generation of downy seeds. ... It is raining instructions out there; it's raining programs; it's raining tree-growing, fluff-spreading, algorithms. That is not a metaphor, it is the plain truth. It couldn't be any plainer if it were raining floppy discs.

It would be pleasant to believe that some of Lincoln's DNA is actively swimming around in somebody's soup, but all the evidence is against it. And of course, there's always the risk that what we might get would be more Robert Todd Lincoln than Abraham Lincoln.

What is not hereditary cannot be permanent.

The general rule is that anything that is passed on in reproduction does not undergo senescence.

Genetics is about how information is stored and transmitted between generations.

and another claimed it was inherited through a parent who was a carrier of the defective gene. I had always assumed the latter was the case with Claire. After all, surely a child who grew out of grief would be born with a heavy heart.

When the husband and wife are healthy, and free from inherited weaknesses and diseases that might be transmitted with injury to their offspring the use of contraceptives is to be condemned.

My whole family is missing that sports gene. I hope I didn't screw that up by marrying a great golfer.

Heredity is a splendid phenomenon that relieves us of responsibility for our shortcomings.

We are, in a way, temporary ambulatory repositories for our nucleic acids. This does not deny our humanity; it does not prevent us from pursuing the good, the true and the beautiful. But it would be a great mistake to ignore where we have come from in our attempt to determine where we are going.

From an evolutionary point of view, sex is really just a reward mechanism to encourage us to pass on our genetic material.

Not one of your pertinent ancestors was squashed, devoured, drowned, starved, stranded, stuck fast, untimely wounded, or otherwise deflected from its life's quest of delivering a tiny charge of genetic material to the right partner at the right moment in order to perpetuate the only possible sequence of hereditary combinations that could result -- eventually, astoundingly, and all too briefly -- in you.

The nucleus has to take care of the inheritance of the heritable characters, while the surrounding cytoplasm is concerned with accommodation or adaptation to the environment.

The nucleic acids, as constituents of living organisms, are comparable In importance to proteins. There is evidence that they are Involved In the processes of cell division and growth, that they participate In the transmission of hereditary characters, and that they are important constituents of viruses. An understanding of the molecular structure of the nucleic acids should be of value In the effort to understand the fundamental phenomena of life.

I have transmitted genetic material, all I have to do between my daughters' birth and my death is to decorate my life.

That the fundamental aspects of heredity should have turned out to be so extraordinarily simple supports us in the hope that nature may, after all, be entirely approachable. Her much-advertised inscrutability has once more been found to be an illusion due to our ignorance. This is encouraging, for, if the world in which we live were as complicated as some of our friends would have us believe we might well despair that biology could ever become an exact science.

Personally, I don't think it is acceptable to manipulate the human germline for the purpose of changing some genetic traits that will be transmitted over generations.

A zygote is a gamete's way of producing more gametes. This may be the purpose of the universe.

The messages that DNA molecules contain are all but eternal when seen against the time scale of individual lifetimes. The lifetimes of DNA messages give or take a few mutations are measured in units ranging from millions of years to hundreds of millions of years; or, in other words, ranging from 10,000 individual lifetimes to a trillion individual lifetimes. Each individual organism should be seen as a temporary vehicle, in which DNA messages spend a tiny fraction of their geological lifetimes.
