DNA is constructed of what?
Polymers,hydrogen bonds,phospho diester bonds,thymine, guanine,chromosomes,etc.
What structures are found in DNA?
Dioxyribose, protein, and nitrogenous bases: thymine, adenine, guanine, cytosine
How do the 4 bases of DNA pair?
The four different nucleotides have different strucutres: Adenine and Guanine have 2 ring structures. However, Cytosine and Thymine have singular ring structures. This means that Adenine cannot pair with Guanine as the two ring structures will be bigger than the singular ringed structure and the two strands of DNA are equidistant the entire length. Adenine and Thymine both have the ability to form 2 hydrogen bonds, whereas Cytosine and Guanine form 3 hydrogen bonds. Therefore Adenine and Thymine bond together, Cytosine and Guanine bond together. These hydrogen bonds between four different types of nucleotides (due to 4 different nitrogenous bases) hold together the two strands of DNA to form a double strand of DNA.
What nitrogen base is replaced with uracil in RNA?
Thymine
What are the 4 nucleotide bases in DNA?
The nitrogen bases found in a DNA molecule are adenine, thymine, cytosine, and guanine.
Which nucleotides pair together?
Pyrimidines in DNA is about equal to the percentage of purines. This is established by Chargoff's rule and is confirmed by the fact that base pairing of anything but a pyrimidine with a purine would be too wide or too narrow to fit within the backbones of a DNA strand

What are the four chemical bases that make the gene's code of instructions?
adenine, cytosine, guanine and thymine
What bases of chromosomes make up DNA?
Adenine, Thymine, Guanine, and Cytosine. A binds to T and C binds to G
Which nucleotide are purines and which are pyrimidine?
Thymine and Cytosine are the pyrimidine nucleotides of DNA, while Adenine and Guanine are the purine structures.
Where is the hereditary information of an organism contain?
Hereditary information, or genetic information, is largely contained within an organism's DNA. DNA is found in the nucleus of cells and is organized into structures called chromosomes. Each chromosome contains hundreds or thousands of genes, which are small sections of DNA that encode instructions for the development and functioning of the organism. Genes contain all of the information needed to make proteins, which are essential for the survival and functioning of the organism. More specifically, hereditary information is broken down into the following components: Nucleotides - Nucleotides are the building blocks of DNA, and they come in four varieties: adenine (A), thymine (T), guanine (G), and cytosine (C). Genes - A gene is a segment of DNA that contains instructions for making a specific protein. Chromosomes - Chromosomes are structures in the nucleus of cells that contain the genetic material. Humans have 23 pairs of chromosomes. DNA - DNA is a molecule that contains the genetic instructions used in the development and functioning of all known living organisms. It is made up of two strands of nucleotides that are twisted together in a double helix.These components are essential to the functioning of an organism, and they are responsible for passing on hereditary information from one generation to the next.
What nitrogenous bases are pyrimidines?
Pyrimidines are the single ringed structures-Cytosine and ThyminePurines are the double ringed structures- Adenine and Guanine.
