RNA/DNA 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 a DNA molecule.
nitrogen bases
Molecules that contain nitrogen and other elements.
adenine
1 of the 4 kinds of nitrogen bases that make up the rungs of DNA; abbreviated A
thymine
1 of the 4 kinds of nitrogen bases that make up the rungs of DNA; abbreviated T
guanine
1 of the 4 kinds of nitrogen bases that make up the rungs of DNA; abbreviated G
cytosine
1 of the 4 kinds of nitrogen bases that make up the rungs of DNA; abbreviated C
gene
A sequence of DNA that determines a trait and is passed from parent to offspring.
DNA replication
Asexual and sexual reproduction
Asexual- one parent, creates identical offspring
Sexual- involves two parents and creates similar offspring
RNA
Ribonucleic acid; the genetic messenger that carries the genetic code from DNA inside the nucleus to the Cytoplasm
uracil
Nitrogen base in RNA found instead of thymine abbreviated U
DNA
Deoxyribonucleic acid; the genetic material that carries information about an organism and is passed from parent to offspring.
