DNA and RNA Flashcards
chromosomes
a threadlike structure within a cell’s nucleus that contains DNA that is passed from one generation to the next
double helix
the shape of DNA
nitrogen bases
molecules that contain nitrogen and other elements that makes of the rungs (middle section) of DNA
adenine
one of the four nitrogen bases that make up the rungs of DNA; it is abbreviated as A
thymine
one of the four nitrogen bases that make up the rungs of DNA; it is abbreviated as T
guanine
one of the four nitrogen bases that make up the rungs of DNA; it is abbreviated as G
cytosine
one of the four nitrogen bases that make up the rungs of DNA; it is abbreviated as C
gene
a section of a DNA molecule that contains the information to code for one specific protein
dna replication
before a cell divides, the process in which dna copies itself
RNA
the messenger that carries the genetic code from the DNA inside the nucleus to the cytoplasm (ribonucleic acis is also known as RNA)
uracil
RNA contains uracil instead of thymine thats in DNA
DNA
Deoxyribonucleic acid; the genetic material that carries information about an organism and is passed from parent to offspring
