Traits as diverse as the color of a person's eyes and the scent of a rose are determined by the information contained in DNA. Learn how this information is coded by strings of molecules called ...

And in every one of the 100 trillion cells, the sequence of these four letters, or bases, is nearly identical. Although the DNA code from cell to cell is the same, there are many different types ...

Combinations of these atoms form the sugar-phosphate backbone of the DNA -- the sides of the ladder, in other words. Other combinations of the atoms form the four bases: thymine (T), adenine (A ...

A team of researchers has used advanced DNA sequencing to develop the most comprehensive atlas yet of genetic change through ...

Double-stranded DNA consists of two polynucleotides that are arranged such that the nitrogenous bases within one polynucleotide ... 3' to 5' direction (Figure 4). It's also critical to understand ...

DNA is made up of four chemical “letters” - the nucleotide bases A, G, T and C. Mutations in this sequence cause thousands of human diseases, yet until recently, gene editing could only fix a ...
