DNA
Deoxyribonucleic Acid; A nucleic acid found in the nucleus of all living cells, which carries the organism's hereditary information.
New cards
2
Chromosomes
rod-shaped cellular structure made of condensed chromatin; contains DNA, which carries the genetic information that controls inherited characteristics such as eye color and blood type.
New cards
3
Nucleotide
in a nucleic-acid chain, a subunit that consists of a sugar, a phosphate, and a base
New cards
4
Double Helix
Shape of a DNA molecule formed when two twisted DNA strands are coiled into a springlike structure and held together by hydrogen bonds between the bases
New cards
5
Adenine
nitrogenous base "A"; connects to thymine in DNA and connects to uracil in RNA
New cards
6
Thymine
nitrogenous base "T"; connects to adenine in DNA
New cards
7
Sugar
The molecule that is bonded between the phosphate and the base in the DNA double helix
New cards
8
Phosphate
The part of the nucleotide subunit that forms the sides or "rails" of the DNA double helix ladder
New cards
9
Cytosine
nitrogenous base "C" connects with guanine
New cards
10
Guanine
nitrogenous base "G"; connects to cytosine
New cards
11
Base
Adenine, Thymine, Guanine, and Cytosine are known as these in DNA
New cards
12
Francis Crick and James Watson
Described the structure of DNA and how it carries genetic information in 1953. Built a three-dimensional model of the molecules of DNA
New cards

Rosalind Franklin
Woman who generated x-ray images of DNA, she provided Watson and Crick with key data about DNA
New cards

Erwin Chargaff
Analyzed the base content of DNA and found that the amount of adenine equaled the amount of thymine and the amount of guanine equals the amount of cytosine.
