The rungs of the ladder in a DNA molecule are made up of nitrogenous bases (adenine, thymine, guanine, and cytosine) that pair up with each other through hydrogen bonds. This base pairing forms the genetic code that carries the instructions for an organism's development and functioning. The sequence of these bases determines the genetic information stored in the DNA molecule.

What parts of the DNA molecule that determine heredity?
Genes
What can be found on the side parts of the ladder-like DNA molecule?
On the side parts of the ladder-like DNA molecule, you will find the sugar-phosphate backbone, which provides structural support to the molecule. The sugar-phosphate backbone serves as the outer framework that holds the nitrogenous bases together in the DNA double helix.
What are the three parts that make up a DNA molecule called?
DNA molecules are actually made up of nucleotides, which is the substance that is made up of three parts. Each nucleotide has a phosphate, a ribose sugar (five-carbon sugar) and a nitrogeneous base (purines-Adenine,Thymine or pyramidines-Guanine,Cytosine). Consider the DNA molecule as a twisted ladder (double helix). The sides of the ladder are actually the phosphate and ribose sugars, and the rungs of the ladder are complimentary nitrogeneous bases of each other. For example, if one side of the rung is the base Adenine, then the complimentary base will be Thymine, vice versa. It is the same for the pyramidines.
Does a molecule have DNA?
DNA is a molecule so no.
If a DNA molecule is compared to a staircase what parts make up the steps?
guanine, cytosine, thymine, adenine.
Which molecule of the Dna upright is the nucleotide rung attached to?
The nucleotide rung of a DNA molecule is attached to the DNA backbone that consists of alternating deoxyribose sugars and phosphate groups. The nucleotide rung itself is composed of a nitrogenous base (e.g., adenine, thymine, guanine, cytosine) attached to a sugar molecule.
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.
What pair forms a rung in the DNA ladder?
The base of the nucleotides
What parts of the DNA molecule that determine heredity?
Genes
How many rungs are in a DNA molecule?
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."
What can be found on the side parts of the ladder-like DNA molecule?
On the side parts of the ladder-like DNA molecule, you will find the sugar-phosphate backbone, which provides structural support to the molecule. The sugar-phosphate backbone serves as the outer framework that holds the nitrogenous bases together in the DNA double helix.
What makes up the ladder of DNA molecules?
The DNA molecule consists of paired nucleotides that make each "rung" of the ladder. Each nucleotide is made up of a one of four nitrogenous bases (adenine, guanine, cytosine, or thymine), a five-carbon sugar (either ribose or 2'-deoxyribose), and a phosphate molecule.
What are the three parts that make up a DNA molecule called?
DNA molecules are actually made up of nucleotides, which is the substance that is made up of three parts. Each nucleotide has a phosphate, a ribose sugar (five-carbon sugar) and a nitrogeneous base (purines-Adenine,Thymine or pyramidines-Guanine,Cytosine). Consider the DNA molecule as a twisted ladder (double helix). The sides of the ladder are actually the phosphate and ribose sugars, and the rungs of the ladder are complimentary nitrogeneous bases of each other. For example, if one side of the rung is the base Adenine, then the complimentary base will be Thymine, vice versa. It is the same for the pyramidines.
A pair of these form a rung in the DNA ladder?
Nucleotides form a rung in the DNA ladder. Each nucleotide consists of a phosphate group, a sugar molecule, and a nitrogenous base. Two nucleotides pair up through hydrogen bonds to connect the two strands of DNA in a double helix structure.
Does a molecule have DNA?
DNA is a molecule so no.
How does the parts of a nucleic acid connect together to make a complete DNA molecule?
In a helix spiral
If a DNA molecule is compared to a staircase what parts make up the steps?
guanine, cytosine, thymine, adenine.
