The Double Helix: A Personal Account of the Discovery of the Structure of DNA is an autobiographical account of the discovery of the double helix structure of DNA written by James D. Watson and published in 1968.
The discovery in 1953 of the double helix, the twisted-ladder structure of deoxyribonucleic acid (DNA), by James Watson and Francis Crick marked a milestone in the history of science and gave rise to modern molecular biology, which is largely concerned with understanding how genes control the chemical processes within cells.
12 de jun. de 2001 · The classic personal account of Watson and Crick’s groundbreaking discovery of the structure of DNA, now with an introduction by Sylvia Nasar, author of A Beautiful Mind.By identifying the structure of DNA, the molecule of life, Francis Crick and James Watson revolutionized biochemistry and won themselves a Nobel Prize.

La doble hélice: una reseña autobiográfica sobre el descubrimiento del ADN (título original: The Double Helix : A Personal Account of the Discovery of the Structure of DNA) es un recuento personal de los eventos acontecidos en torno al descubrimiento de la estructura de la molécula del ADN en la década de 1950, escrito por el biólogo molecular e...
The structure of DNA, as represented in Watson and Crick's model, is a double-stranded, antiparallel, right-handed helix. The sugar-phosphate backbones of the DNA strands make up the outside of the helix, while the nitrogenous bases are found on the inside and form hydrogen-bonded pairs that hold the DNA strands together.
- A codon is the name for a group of three subsequent nucleotides in RNA. Since RNA is transcribed from DNA, the DNA sequence will determine the sequ...
- As far as the 2nd question is concerned , it is because the double helix should have a uniform diameter all throughout otherwise there might be pro...
- Not exactly. The amount of each type of base in a cell's DNA is the _same in all cells in the whole organism_. Genetic code is the same, but gene e...
- Seems mostly correct. The one mistake I notice is that I think the word you were looking for was histones (not histamin). Chromatin is composed of...
- I'm not sure it is the NH2 group which accepts protons most readily to make it a base. I think it could be the nitrogens in the rings, which I thin...
- You can tell if if the helix is right handed or left handed based on the way it twists. Here's a link to an image that shows the difference between...
- I will answer you the way I have answered this question before with other users. I hope it is adequate. There are several differences. To start, DN...
- The four nitrogenous bases are as follows: Adenine, Thymine, Guanine, and Cytosine. Cytosine and Thymine are pyrimidines Adenine and Guanine are pu...
- There isn't a single order — all combinations along a strand are possible. The only thing that is fixed in DNA is that A pairs with T, and G pairs...
11 de ago. de 2021 · Since its publication in 1968, 'The Double Helix' has given over a million readers a rare and exciting look at one highly significant piece of scientific research--Watson and Crick's race to discover the molecular structure of the gene.
8 de dic. de 2021 · The 3-dimensional double helix structure of DNA, correctly elucidated by James Watson and Francis Crick. Complementary bases are held together as a pair by hydrogen bonds.
