In the backstone of each strand in the DNA double helix molecule, the sugar of one nucleotide is bonded to the ___________ in the next nucleotide.
phosphate group
To find the answer to this question, you can refer to a reliable source such as a biology textbook or an online resource. However, I can provide you with the information you're looking for.
In the DNA double helix molecule, the sugar of one nucleotide is bonded to the phosphate group in the next nucleotide. This bond, known as a phosphodiester bond, forms between the 3' carbon of the sugar in one nucleotide and the 5' carbon of the sugar in the next nucleotide, creating a sugar-phosphate backbone. This backbone runs along the length of the DNA strand and provides stability to the molecule.
