A DNA molecule is composed of Deoxyribose, sugar base, bonded to phosphate by a covalent bond, which according to if Adenine and Thymine bond, will results in a double hydrogen bond, or Guanine and cytosine which results in a triple hydrogen bond. The DNA molecule is a double stranded helix wich is anti-paralell, because one goes in the direction of 5'-3' and the other one from 3'-5'. Which is why the lagging strand 3'-5' requires additional enzymes for replication.

What does the DNA look look like?
You get a toy ladder and twist it repeatedly. You get the two spring like structure, going parallel to each other. DNA helix looks like the same.
If organisms have the same bone structure would they have the same DNA?
no because the DNA doesn't make up what your bone structure will look like it just means they inherited it from there ancestors.

It looks the same as it does everywhere else. DNA is DNA. Its structure is the same everywhere.

What do biologists look at when they classify an animal?
Biologists classify animals by their body structure, the way their body structure develops, and by their DNA.
What does DNA look like when it's clumped together?
When DNA is clumped together, it takes on a condensed and compact structure known as chromatin. In this state, DNA is wrapped around proteins called histones to form nucleosomes, which then further coil and condense to form chromosomes. This condensed structure allows DNA to be packed efficiently within the cell nucleus.

Chromosome.
What is the structure of DNA like?
nucleic acid arranged in a double helix
