DNA is a double stranded molecule in which nitrogenous bases are linked together. Watson and crick explained that DNA strand are antiparallel. The antiparallel nature of the strand means one DNA gas a polarity of 5' to 3' direction whereas the another strand of the DNA gas polarity of 3' to 5' direction. These two strands has opposite polarity and runs in anti parallel directions. Thus, the DNA strand known as antiparallel strands.

We could look at biolgy and see how photosynthesis makes use of energy. In photosynthesis we see plant cells converting energy from the sun into usful sugars to help the plant grow.
Now we could look at astronomy and see how energy is used, If you observe stars you can see the different brightnesses and masses, which tells you alot about what type of energy conversion is happening inside the star (nuclear fusion).
