DNA. RNA Flashcards
Chromosomes
A threadlike structure whiten the cells nucleus that contains DNA that is passed from one generation to another
Double helix
The shape of the DNA molecule
Nitrogen base
Molecules that contain nitrogen and other elements
Adenine
a compound that is one of the four constituent bases of nucleic acids. A purine derivative, it is paired with thymine in double-stranded DNA.
Thymine
a compound that is one of the four constituent bases of nucleic acids. A pyrimidine derivative, it is paired with adenine in double-stranded DNA.
Gene
A sequence of DNA that determines a trait and is passed parent to offspring
DNA replication
Before a cell divides, the process in which DNA copies itself
RNA
Ribonucleuc
DNA
Genetic materials that carries information about an organism and is passed by a parent to an offspring
Uracil
A nitrogen base found in RNA instead of thymine abbreviated U.
Nitrogen bases
containing organic compound that has the chemical properties of a base, especially a pyrimidine or purine:
Guanine
a compound that occurs in guano and fish scales, and is one of the four constituent bases of nucleic acids. A purine derivative, it is paired with cytosine in double-stranded DNA.
