BIO 1500 chapter 11
1. Some DNA analysis applications:: forensics, determining paternity, identifying pathogens, tracing
disease outbreaks, diagnostics within medical fields, vaccine development, cancer therapy,...
2. What is a nucleotide composed of?: - a deoxyribose sugar (5C)
- a nitrogenous base (adenine (A), cytosine (C), guanine (G), or thymine (T)),
- a phosphate group
3. What does DNA stand for? What is it composed of?: Deoxyribonucleic acid: double-strand-
ed, helical nucleic acid molecule, consisting of monomers "nucleotides"
4. Capable of being replicated and determining the inherited structure of a cell's
protein:: DNA (polymer)
5. : any of the alternative versions of a gene that may produce
distinguishable phenotypic effects: Allele
6. DNA -> RNA =...
,RNA -> protein =...: transcription, translation
7. - Current understanding of DNA began with the discovery of
- In 1860s, physician Friedrich Miescher, isolated -rich chemicals
from WBC (leukocytes).
- He named them because were isolated from the nuclei of cells
(would eventually be known as DNA)
- Followed by the development of the - model by Wat-
son and Crick: nucleic acids, phosphate, nuclein, double-helix
8. In April 1953, who shook the world with the double-helical model for the
structure of DNA?: James Watson and Francis Crick
9. and were the candidates for the genetic material (ma-
, terial of inheritance)
Until the 1940s, case for seemed stronger especially since identi-
fied as class of macromolecules with great diversity and specificity of function,
essential requirements for hereditary material
WHY NOT NUCLEIC ACIDS?: DNA, Protein, proteins
- little was known about them
