Now that you have identified the components of dna, can you describe how these components bind together to form a dna molecule

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.

imagine a line passing through the center of earth that goes through both the north pole and the south pole. this imaginary line is called an axis. earth spins around its axis, just as a top spins around its spindle. this spinning movement is called earth's rotation. at the same time that the earth spins on its axis, it also orbits, or revolves around the sun. this movement is called revolution.
