HIS OWN IMAGE ?

DNA bases pair up with each other , A with T and C with G , to form units called base pairs . Each base is also attached to a sugar molecule and a phosphate molecule . Together , a base , sugar , and phosphate are called a nucleotide . Nucleotides are arranged in two long strands that form a spiral called a double helix .
