Unit 2 Vocabulary - DNA

published their correct findings that DNA is a Double - Helix and that the helices (strands) must be anti-parallel to one another.

• Watson & Crick

• Rosalind Franklin

• Frederick Griffith

made the DNA X-Ray diffraction patterns and took Photo 51

• Watson & Crick

• Rosalind Franklin

• Frederick Griffith

Used mice and streptococcus pneumoniae. Questioned what chemical component was responsible for the transformation principle

• Watson & Crick

• Rosalind Franklin

• Frederick Griffith

Performed the Hershey-Chase blender experiment usingT2 Viruses and E. Coli to establish that DNA is the material that viruses(bacteriophage)transfer to their host.

• Hershey & Chase

• Erwin Chargaff

• Levene

stated that there is an equal number of Thymine to Adenine and an equal number of Guanine to Cytosine.

• Hershey & Chase

• Erwin Chargaff

• Levene

shown that each nucleotide building block of DNA is made up of a phosphate group linked to a deoxyribose sugar.

• Hershey & Chase

• Erwin Chargaff

• Levene

Nitrogen bases that link together in the formation of DNA based on their fit.

• Complmentary Base-pairs

• Deoxyribose Sugar

• Nitrogen Base

• Phosphate group

A part of the nucleotide that helps form the backbone of DNA. This specific part of the backbone contains phosphorus.

• Complmentary Base-pairs

• Deoxyribose Sugar

• Nitrogen Base

• Phosphate group

A part of the nucleotide that helps form the backbone of DNA. This specific part of the backbone is a ringed structure containing only carbon, hydrogen, and oxygen.

• Complmentary Base-pairs

• Deoxyribose Sugar

• Nitrogen Base

• Phosphate group

A part of the nucleotide that actually attaches to the complementary DNA strand. This specific part of the nucleotide contains nitrogen.

• Complmentary Base-pairs

• Deoxyribose Sugar

• Nitrogen Base
