Atoms in each DNA nucleotide can be identified by specific numbers. The ends of a DNA molecule are called 3' and 5' ends, based on the numbering of carbon.
Remember, when writing complementary DNA sequences, you need to write the sequence in the 5' to 3' direction. This usually involves reversing the sequence.
When nucleotides are incorporated into DNA, adjacent nucleotides are linked by a phosphodiester bond: a covalent bond is formed between the 5’ phosphate group of one nucleotide and the 3’-OH group of another (see below). In this manner, each strand of DNA has a “backbone” of phosphate-sugar-phosphate-sugar-phosphate.
