DNA/RNA Flashcards
Chromosomes
A threadlike structure in a cell’s nucleus that contains DNA, and it 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
A type of nitrogen base that makes up rungs of DNA (A) pairs up with T
Thymine
Another type of nitrogen base that makes up rungs of DNA (T)
Pairs up with A
Guanine
A type of nitrogen base that makes up rungs of DNA (G)
Pairs up with C
Cytosine
Another type of nitrogen base that makes up rungs of DNA (C)
Pairs up with G
Gene
A sequence of DNA that determines a trait of an offspring. It is passed on from a parent to an offspring. Contains information to code for a specific protein.
DNA replication
The process of which a DNA strand copies itself before it divides
DNA
Deoxyribonucleic acid ( Dna) a genetic material that carries information about an organism. It is passed from a parent to a offspring.
RNA
Ribonuclease acid; the genetic messenger that carries the genetic cod from DNA inside the nucleus to the cytoplasm
Uracil
A nitrogen base found in RNA instead of thymine (U)
