DNA Structure
Term | Definition |
---|---|
Nucleotide | an organic compound that consists of a sugar, a phosphate, and a nitrogenous base |
Monomer/Polymer | Nucleotide/DNA |
Adenine | A nitrogen base (purine) that bonds with Thymine |
Thymine | A nitrogen base (pyrimidine) that bonds with Adenine |
Guanine | A nitrogen base (purine) that bonds with Cytosine |
Cytosine | A nitrogen base (pyrimidine) that bonds with Guanine |
Deoxyribose sugar | The sugar found in a nucleotide of DNA. (The D in DNA stands for deoxyribose) |
carbohydrate ring | The sugar ring found in a nucleotide (AKA Deoxyribose sugar) |
Double Helix | The model that shows the structure of a DNA molecule. Two strands wind around one another. |
Phosphate group | Part of a nucleotide in the sugar-phosphate backbone. Contains phosphorous. |
Hydrogen bonds | The type of chemical bond between base pairs in DNA |
CHONP | Elements found in nucleic acids |
complementary bases / complementary nucleotide | Cytosine ALWAYS bonds with Guanine and Adenine ALWAYS bonds with Thymine |
Sugar phosphate backbone | The outside, ribbon like, part of DNA made of phosphate groups and deoxyribose sugar molecules |
Rungs of double helix (DNA) | The inside section of DNA. Made of nitrogenous base pairs. |
Base pair | When two bases form a hydrogen bond (A bonds with T, C bonds with G) |
Chromosomes | Long , continuous thread of DNA that consists of numerous genes and regulatory information |
Genetic Code | DNA is the genetic code |
Blueprint for all life | DNA structure is the same in ALL life. |
traits | A characteristic that is inherited |
genes | A specific region of DNA that codes for a particular protein |
