· In DNA a phosphate group (PO 43) is attached to the 3′carbon of deoxyribose sugar and 5′carbon of another sugarTherefore, each strand contains 3′ end and 5′ end arranged in an alternate manner Strong negative charges of nucleic acid are due to the presence of phosphate groupsOf one phosphate group, one sugar ring, and one nitrogencontaining base • DNA has 4 types of bases Adenine, Thymine, Cytosine, and Guanine (A, T, C, and G) These bases have strict binding rules, as A only bonds with T (and vice versa), and C only bonds with G This is important for DNA replication to workAnswer to Label the DNA molecule Hydrogen bond Phosphate group Phosphodiester bond Deoxyribose sugar Nitrogenous base
