Poly nucleotide chain .
The sides or railings of DNA are made up of alternating sugar (deoxyribose) and phosphate molecules, forming the backbone of the DNA molecule. The rungs or steps of DNA are made up of nitrogenous bases (adenine, thymine, cytosine, and guanine) which form hydrogen bonds to connect the two strands of the DNA molecule in a complementary manner.
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).
The ladder had 25 rungs in total. This can be calculated by adding the 7 rungs walked down to the 15 rungs climbed up, then adding the final 3 rungs. So, 7 + 15 + 3 = 25 rungs on the ladder.
Yes, the DNA molecule is made up of segments of coding called Genes. Each gene codes to make a different protein or genetic characteristic.
If the rungs are perpendicular to one side of the ladder, then they must be parallel to the other side of the ladder. This is because if one side is perpendicular to the rungs, the other side, being parallel to the first side, will also be perpendicular to the rungs.
A DNA molecule consists of two strands that are connected by hydrogen bonds between complementary bases. Each strand has a backbone made up of alternating sugar and phosphate groups, with bases extending inward. The number of rungs in a DNA molecule depends on the length of the molecule, with each base pair forming one "rung."
In a DNA molecule, the sides are made up of alternating sugar and phosphate groups bonded together. These sugar-phosphate backbones provide structural support to the DNA molecule. The rungs of the DNA ladder are made up of nitrogenous bases that form hydrogen bonds between complementary base pairs.

The sides of the DNA molecule are made up of repeating sugar-phosphate groups, not nitrogen bases. The nitrogen bases are arranged in the middle of the DNA molecule and form the rungs of the double helix structure.
DNA molecules consist of chains of nucleotides arranged like rungs on a twisting ladder, forming the double helix structure. The nucleotides in DNA are made up of a phosphate group, a sugar molecule, and a nitrogenous base. The arrangement of these nucleotides determines the genetic information stored in the DNA molecule.

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.

DNA's rungs are made from a purine that is longer and always Guanine (G) or Adenine (A) and a pyrmidine which is small and always Cytosine (C) or Thymine (T). So each DNA rung is always equal with a base pair of ( A ) and ( T ) or ( G ) and ( C ).
