DNA does not have DNA in it, in the same sense that a person does not have a person in them. DNA is made up of smaller molecules [deoxyribose (sugar-phosphate) backbone with nucleoside bases] but the...
A-DNA is similar to B-DNA, but with a shorter helix. B-DNA is the most common kind, and has a major and minor groove with a similar depth. Z-DNA is left-handed, whereas A and B-DNA are right handed....
Mouse (murine) DNA is more similar to human DNA. The genomes are roughly the same size with a similar number of genes. Dog (canine) DNA has fewer genes than both human and mouse DNA and have fewer...
