DNA Strand Diagram | Biology
The below mentioned article provides a diagram of DNA strand. (a) DNA is made up of two polynucleotide chains. The backbone is constituted by sugar-phosphate, while the nitrogenous bases project inwards. (b) The two chains have anti-parallel polarity. Therefore, when one chain has 3' → 5'polarity, the other chain has 5' → 3' polarity. (c) The bases in two strands [...]
