Quotes About Chromosomes

I must have been in junior high school when a scientist reported (mistakenly, as it turned out) that LSD scrambled your chromosomes; the entire media, as well as my health-ed teacher, made sure we heard all about it.

You have three chromosomes, Bryson. X, Y, and Fuckhead. -- Katz

DNA molecule, as you will almost certainly remember from countless television programs if not school biology, is made up of two strands, connected by rungs to form the celebrated twisted ladder known as a double helix. Your DNA is simply an instruction manual for making you. A length of DNA is divided into segments called chromosomes and shorter individual units called genes. The sum of all your genes is the genome.

En réalité, puisque si peu de personnes font examiner leurs chromosomes, on pourrait défendre l'idée que dans la grande majorité des cas, les genTEs ont un sexe génétique qui reste encore à déterminer.

Drosophila has long been our main workhorse in genetics, yielding insight in the relation between chromosomes and genes.

In one widely publicized study, a researcher reported in Science that LSD could damage chromosomes, potentially leading to birth defects. But when the study was later discredited (also in Science), the refutation received little attention. It didn't fit the new public narrative of LSD as a threat.

Until fairly recently it was thought that humans had fortv-eight chromosomes in an ordinary somatic cell. We now know that the correct number is forty-six. Chimps apparently really do have forty-eight chromosomes, and in this case a viable cross of a chimpanzee and a human would in any event be rare.

Of course there is no doubt that some diseases, like Huntington's chorea, beta thalassemia, and cystic fibrosis, can be blamed entirely on one faulty gene. But single-gene

I haven't learned How or why Universe contrived to implode And intellectually code The myriadly unique Chromosomically orchestrated DNA-RNA, Quadripartite moleculed, Binary paired, Helically extended And unzippingly dichotomied Regenerative symphonic jazz, as A one and two, Three and four Me---You, Thee---They And more Thine and mine, Sweet citizen, THYMINE-CYTOSINE GUANINE-ADENINE

One may code for wrinkles, while the other holds the blueprint for smooth. As long as they stay together, only the stronger of each pair rules. Eukaryotes took advantage of this disagreement between twins. Prokaryotes had xeroxed chromosomes in their entirety. But eukaryotes unzipped their chromosomal ribbons lengthwise, ever-so gently separating each genetic pair. This yielded two skinny juliennes,‡ each with slightly different properties.

The dividing eukaryote could not aggressively seek food. Nor could it avoid predatory one-celled creatures whipping through the water in search of someone to eat. The solution: to concentrate spirochetic propellers on the outside of one cell, then to generate an attached cell whose spirochetes could stay inside directing the dance of twining and dividing chromosomes. This, according to Margulis, would start the run-up to another massive leap in the evolution of networks: multicellularity.

Richard Nixon has never been one of my favorite people, anyway. For years I've regarded his very existence as a monument to all the rancid genes and broken chromosomes that corrupt the possibilities of the American Dream; he was a foul caricature of himself, a man with no soul, no inner convictions, with the integrity of a hyena and the style of a poison toad.

Each part of our genome is unique. We would not be alive if there was not a single mathematical solution for our chromosomes. We would just be scrambled goo.

We humans have 23 pairs, but pea plants have only 7. Yeast have 16. Some butterflies have 134.

Chromosomes were chemical mixtures, including proteins as well as a mysterious molecule called deoxyribonucleic acid, or DNA for short.

When a cell divides, it needs another army of molecules to make a second copy of its DNA.

He made himself as small as possible behind the parapet, holding the gun awkwardly above it, and aimed by the screensight image patched to his glades. His trigger finger pressed Enter. The weapon took over, it aimed him. In a second the head-up image showed four bodies, sprawled, stapled down like X- and Y- chromosomes.

Closely related species of birds are also chromosomally similar.

Although each egg cell produced by a woman carries a single X chromosome, the sperm cells produced by a man carry either an X or a Y. This means, in very simple terms, that the sperm cell determines a baby's sex.

For each chromosome contributed by the sperm there is a corresponding chromosome contributed by the egg, there are two chromosomes of each kind, which together constitute a pair.

My first ideas of human in vitro fertilization (IVF) arose with my Ph.D. in Edinburgh University in the early 1950s. Supervised by Alan Beatty, my research was based on his work on altering chromosomal complements in mouse embryos.

My grandfather had two boys, my uncle had three boys, my dad had me and my two brothers, each of my brothers have had two boys. Then something happened with the chromosomal experiment and suddenly I've got three girls.

The egg of every species of animal or plant carries a definite number of bodies called chromosomes. The sperm carries the same number. Consequently, when the sperm unites with the egg, the fertilized egg will contain the double number of chromosomes.
