Answer: DNA has three components a phosphate group, a sugar deoxyribose and 4 nitogenous bases.
DNA has two important bonds that make up the DNA which are phosphodiester bond and hydrogen bonds.
Explanation:
The phosphate of the one nucleotide in DNA bonds with the 5 sugar (5' carbon) of the next nucleotide forming the PHOSPHODIESTER BOND which is a strong covalent bond.
The other bond in DNA is the hydrogen bonds which are among the nitrogenous bases.
There are four bases adenine,guanine,cytosine,thyamine
These bases are held together by strong hydrogen bonds.
Adenine and thyamine have two hydrogen bonds between them and cytosine and guanine have three hydrogen bonds between them.
These hydrogen bonds keeps the DNA helix in place.

Nitrification!!!!!!!!!!!!!!!!!!!!!!! <span />
With every organism in the world they all have the same base pairing rules. The rule are that "a" pairs with "t" and "g" pairs with "c". This rule will change when the DNA is copied into MRNA but just just keep it simple.
If I have the DNA code

I hope this makes sense, if it doesn't then let me know. Have a Great day!
