A DNA molecule made in vitro with segments from different sources
25 rungs
DNA is an example of a macromolecule, i.e. a large molecule with a special shape, which is built up from many smaller parts called sub-units .If you could magnify part of a nucleus, you would see the DNA molecule looking like a twisted rope ladder - a double helix. The two strands forming the sides of the ladder give it a strong yet flexible structure, which does not vary along its length. Stretched between these are the "rungs" of the ladder, the parts of the DNA molecule which vary, and so the differences carry genetic information. These parts are made up of sections called bases, which fit together in pairs. Single section of DNA The 4 bases (so called because on their own they react with acids) are also usually known by their initials, as shown alongside: A (adenine), paired with T (thymine) and C (cytosine) paired with G (guanine).
Yes, the DNA molecule is made up of segments of coding called Genes. Each gene codes to make a different protein or genetic characteristic.
The rungs are perpendicular to both sides

The four nitrogen bases, Guanine, Cytosine, Thymine, and Adenine. Thymine and Cytosine are pyrimidines and Guanine and Adenine are purines. Thymine bonds with Adenine and Cytosine bonds with Guanine.
Genes are made of segments of
A polygon
The rungs are perpendicular to both sides
A wooden ladder usually have rungs made from wooden dowels with tapered ends. An aluminium ladder would have extruded aluminium rungs.
The 'steps' or 'rungs' of the DNA 'ladder' are complimentary pairs of bases bonded by hydrogen bonds. The bases are Adenine, Thymine, Cytosine and Guanine. Adenine always bonds to Thymine and Cytosine always bonds to Guanine.
