DNA
What is a bundle of DNA in a cell called?
chromosome
Characteristics that are passed from parent to offspring through genes.
inherited traits
The base that pairs with Cytosine in DNA.
guanine
The base that pairs with Guanine in DNA.
cytosine
nucleic acid made of phosphate, sugar, and a nitrogen base.
nucleotides
a molecule that can be a temporary copy of DNA sequence and helps produce proteins, ribonucleic acid.
RNA
A reproductive process that involves two parents that combine their genetic material to produce a new organism, which differs from both parents

What does DNA look like?
twisted ladder or double helix

Punnett square
What nucleotides bond with each other?
G and C
A and T
A type of mutation where a DNA sequence (base pair) is left out is called?
deletion
remnants of features that served a function in the organism's ancestors, the structure are no longer be used by organism, due to evolution.
Body parts that share a common function, but not structure
analogous structure
Structures that are similar in different species and that have been inherited from a common ancestor, but serve a different function
homologous structure

insertion

the resemblance of one organism to another organism or its surroundings for protection
The hiding of something as a result of its appearance
Describe 2 out of 3 adaptions
structural-a change in body part or structure
behavioral-animal changes the way it acts
