Frederick Griffith
Found out that bacteria can pass on traits to each other.
Nucleotide
The small pieces that make up DNA.
Nitrogenous bases
The "letters" in DNA (A, T, G, C).
Purines
Two of the DNA letters: A and G.
DNA Polymerase
A helper that copies DNA.
Base pair rule
A pairs with T, and G pairs with C in DNA.
Oswald Avery
Discovered DNA as transforming principle.
Backbone
The sides of the DNA "ladder."
Watson & Crick
Found the shape of DNA (double helix).
Rosalind Franklin
Used x-ray crystallography to determine DNA shape. (x)
G1 & G2 phases
Times when the cell grows and gets ready to divide.
Semi-conservative replication
Each new DNA strand has one old side and one new side.
Hershey & Chase
Confirmed DNA is the genetic material.
Pyrimidines
Two of the DNA letters: C and T.
Cell cycle
The stages a cell goes through to grow and divide.
Histones
Protein that helps package and organize DNA.
Chargaff
Found that A matches T, and G matches C.
S phase
The stage when DNA is copied.
Cytokinesis
When the cell fully splits into two.
M phase
When the cell divides.
Chromosome
Structures made of DNA; they hold genes.
Chromatin
DNA wrapped around proteins, makes up Chromosomes.
Sister chromatids
Copies of chromosomes ready to split during division.
Steps of mitosis
Interphase, Prophase, Metaphase, Anaphase, and Telophase and cytokinesis.
Apoptosis
Programmed cell death.
Malignant tumor
A harmful, spreading tumor (cancer).
Benign tumor
A harmless tumor that doesn't spread.
Tumor suppressor genes
Genes that stop cells from growing too much.
Cancer
Uncontrolled cell growth.
Prokaryotes
Cells without a nucleus.
Eukaryotes
Cells with a nucleus.
Binary fission
A simple cell dividing into two identical cells.
Asexual reproduction
Making an exact copy of a single parent.
Sexual reproduction
Combining DNA from two parents to make varied offspring.
Purpose of mitosis
To make 2 identical cells.
