I'll assume you're talking about the "double helix" structure which looks like a twisted ladder, rather than an electrophoresis gel plate film.

DNA is a double stranded sequence of nucleic acids... on one side a "protein code" is made using Adenine, Thymine, Guanine, Cytosine.

On one side, each of these nucleic acids is punctuated by a phosphate group.

Each "rung" on the ladder is formed by hydrogen bonds between one side and the other. Adenine bonds to Thymine and Guanine to Cytosine.

Hydrogen bonds are formed when an exposed hydrogen atom, which is covalently bonded to an electronegative atom, is in close proximity to another exposed electronegative atom. This happens because the hydrogen atom has a relatively positive charge and the juxtaposed electronegative atom is relatively... well, negatively charged.

The DNA double helix looks like a twisted ladder What makes up each rung of the ladder What makes up the sides of the ladder What holds the rungs together at the sides?

Each rung of the DNA double helix is made up of a pair of nitrogenous bases (adenine-thymine or guanine-cytosine). The sides of the ladder are made up of alternating sugar (deoxyribose) and phosphate molecules. Hydrogen bonds hold the nitrogenous bases of the rungs together, creating the structure of the DNA double helix.


What group makes up the rungs or steps of DNA?

The rungs or steps of DNA are made up of nucleotide bases. There are four types of nucleotide bases: adenine (A), thymine (T), cytosine (C), and guanine (G). These bases pair up in a specific way (A with T and C with G) to form the rungs of the DNA ladder.


What makes up the rungs of the DNA ladder?

The rungs of the DNA ladder are made up of nitrogenous bases, specifically adenine (A) always pairs with thymine (T), and guanine (G) always pairs with cytosine (C). These base pairs are held together by hydrogen bonds, forming the double helix structure of DNA.


What makes up the sides of a DNA strand?

A DNA strand is made up of alternating sugar (deoxyribose) and phosphate molecules. The nitrogenous bases (adenine, thymine, cytosine, and guanine) are attached to the sugar molecules, forming the "rungs" of the DNA ladder.


What makes up the side of the DNA ladder?

Phospate groups and dioxyribose sugars. the "rungs" are made up of the four nitrogen bases--adenine, thymine, guanine and cytosine.


What is the rung of the DNA ladder?

The rungs that are in the DNA ladder molecule are nucleotides. They are adenine, guanine, thymine and cytosine. Deoxyribose and phosphate make up the backbone of the molecule.

thymines, guanines, adenines, and cytosines


What two chemicals make up the rungs of the DNA ladder?

The two chemicals that make up the rungs of the DNA ladder are adenine (A) paired with thymine (T), and guanine (G) paired with cytosine (C). These base pairs connect the two strands of the DNA double helix together.


What molecules make up the rungs of a DNa ladder?

The rungs of a DNA ladder are made up of nucleotide base pairs. These base pairs consist of adenine (A) paired with thymine (T), and guanine (G) paired with cytosine (C).
