B NUCLEIC ACIDS

Nucleic Acids Nucleic acids • Polymers of nucleo des are termed polynucleo des or nucleic acids, be er known as DNA and RNA. •  Each nucleic acid is made from just four different nucleo des. •  RNA contain the bases adenine, cytosine, guanine, and uracil •  DNA contain adenine, cytosine, guanine, and thymine. • Polymeriza on involves the phosphate and sugar groups of the nucleo des, which become linked by phosphodiester bonds • primary role: act as ca...
