Term
DNA
Definition

Deoxyribonucleic acid 

Self replicating material that controls all traits of an organism

Term
Nuceotide
Definition
A small compound in DNA. Consists of a phosphate, sugar, and a base.
Term
Adenine
Definition

A base, always pairs with Thymine

 

Term
Thymine
Definition
A base, pairs with Adenine
Term
Guanine
Definition
A base, pairs with Cytosine
Term
Cytosine
Definition
Base, pairs with Guanine
Term
Double Helix
Definition
A pair of parallel helices intertwined about a axis, DNA molecule structure
Term
Gene
Definition
Samll unit of chromsomes and DNA. Unit of heridity transferred from parent to offfspring.
Term
Replication
Definition
[image]
The double helix is unwound and each strand acts as a blueprint for the next strand. Bases are matched to complimentary bases. New partner strands form. Is the process of producing two identical replicas from one original DNA molecule.
Term
Complimentary Bases
Definition
Bases that can only bond with another are complimentary.
Term

Base Pair Rule

Definition

A - T

C - G

Each base will only bond with one other base.

Term
Rosalind Franklin
Definition
Took x-ray diffractions of DNA molecule. The frequency of waves suggested a double helix shape.
Term
Watson and Crick
Definition
James Watson and Francis Crick are the first people to make a model of DNA. They revealed DNA's true form. This helped explain how Dna was copied and how it controlled the cell. The model matched with Chargraff's and Franklin's discoveries
Term
Chargraff
Definition
Edwin Chargraff founs that the Adenine is always equal to thymine. Same with Guanine and Cytosine. i.e, 20% A=20% T=30% C= 30% G
