In a DNA molecule cytosine always pairs with guanine, the same is true for an RNA molecule.
the parent cell
Mutation
A characteristic of a DNA molecule that is not characteristic of a protein molecule is that the DNA molecule can replicate itself.
watson and crick, because they discovered the theory first
AT and GC
Base Pair
guanine-cytosine
iron
The second DNA is an exact duplicate of the first. If not the second will not work correctly. We call this a mutation.
The order of the bases in each new DNA molecule exactly matches the order in the original DNA molecule by bringing them together with the original DNA cells.
In a DNA molecule cytosine always pairs with guanine, the same is true for an RNA molecule.
Guanine-Cytosine
according to my calculations, the answer to this question is a single circular DNA molecule... your welcome (:
DNA base pair are Cytosine with Guanine and Thymine with Adenine.
A-T and C-G
Guanine an thymine
