Shape of DNA Double Helix
Scientists credited for the discovery of the structure of DNA Watson and Crick
The person who took X-Ray diffraction photographs of DNA crystals Rosalind Franklin
Adenine and guanine Purines
Thymine and cytosine Pyrimidines
American biochemist who observed that the percentage of adenine equals the percentage of thymine, and the percentage of cytosine equals that of the guanine in the DNA of a variety of organisms Erwin Chargaff

Purine compatible with cytosine Guanine
Pyrimidine compatible with adenine Thymine
Pyrimidine compatible with guanine Cytosine
Process of copying DNA Replication
Made up of 3 parts: sugar (deoxyribose) , phosphate (phosphorous) and one of four nitrogen containing bases (A, G, T, C) DNA Nucleotide
Enzymes that bind to the separated chains of DNA DNA Polymerase

The production of proteins Protein Synthesis
There are 20... Amino Acids
The process of assembling polypeptides from information encoded in mRNA Translation
The loop opposite of the site of amino acid attachment bears a sequence of three nucleotides called an... Anticodon
DNA is made up of repeating subunits of Nucleotides
