• Double-stranded

DNA Structure

• Double-stranded• Covalent bonds

between phosphate and sugar

DNA Structure

• Double-stranded• Covalent bonds

between phosphate and sugar

• Two strands held together by hydrogen bonding between complimentary base pairs

DNA Structure

• Described as having two antiparallel strands (aligned in opposite directions)
