What are functions of a DNA molecule?

Question

I have a project due this wednesday, and I don't know anything about DNA. I need to know the parts of DNA, and its functions.

Answer 1

dna is made up of deoxyribose sugar, phosphate molecule n a nitrogen base. it is used as genetic material to transfer the genetic material from one generation to other. it is basically used in processes like replication n transcription

Answer 2

You'll get more info from the wikipedia article on DNA than you will on this site.  

DNA is comprised on nucleotides that attach to each other.  Each nucleotide has a 5-carbon sugar, a phosphate group (made of phosphorous and hydrogen), and a base.  A base is adenine, thymine, cytosine, or guanine.  A whole bunch of nucleotides forms a strand.  Each strand's bases connects to the bases of a second strand.  Together, these two strands form a double helix shape.  The two strands are complimentary, meaning that the order of the bases for each nucleotide willl be the opposite.  (Adenine and thymine are opposites, as are cytosine and guanine.)  For intance, if one strand's code is adenine, guanine, cytosine... the compliment would read thymine, cytosine, guanine.  

Function: The list of bases can be transcribed via RNA and brought to ribosomes, where the code corresponds to amino acids, the building blocks of proteins.  As a result, the code acts as a blueprint for producing proteins.
