100
An idea or assertion that cannot be experimentally proven false, and cannot be experimented or investigated scientifically.
What is pseudoscience?
100
This type of chemical bond is caused by atoms sharing electrons.
What is a covalent bond?
100
A nickname for water due to its ability to dissolve ions, be cohesive, and resist change in temperature.
What is the universal solvent?
100
This is the famous structure of DNA, uncovered by James Watson, Francis Crick, and Rosalind Franklin.
What is a double helix?
100
These are not polymers, hydrophobic, used for energy storage and insulation, and joined together by ester linkages.
What is a lipid?
200
1. Observation 2. Question 3. Hypothesis 4. Experiment 5. Conclusion 6. Revision of Hypothesis...
What is the scientific method?
200
This functional group looks like: O=C-OH
What is a carboxyl group?
200
This is a solution that minimizes or resists pH changes by absorbing protons (H+), usually made up of an acid-base pair.
What is a buffer?
200
The idea that DNA is broken into discrete genes, which are transcribed into RNA, which are translated into proteins.
What is the central dogma?
200
These bonds join together simple sugars to create polysaccharides.
What is a glycosidic linkages?
300
Type of reasoning that states where the conclusion is a necessary consequence of premise or facts. General to specific. Good for testing hypotheses.
What is deductive reasoning?
300
These are the four essential elements of life.
What is CHON?
300
These are molecules with the same chemical formula but a different arrangement of atoms and/or bonds.
What is are isomers?
300
What is the site of mRNA translation?
What is the ribosome?
300
These reactions break polymers apart into monomers by adding water.
What are hydrolysis reactions?
400
This term is based on many experimental observations (inductive reasoning), and is able to make falsifiable predictions. (deductive reasoning)
What is scientific theory?
400
This study whether life molecules could form under conditions similar to the atmosphere of early earth.
What is the Miller-Urey experiment?
400
The ability of carbon to form four covalent bonds with its four valence electrons.
What is tetravalence?
400
These state that within a DNA strand, the amount of adenine is equal to thymine, and cytosine is equal to guanine.
What are Chargaff's rules?
400
This is a type of molecule with a hydrophobic and hydrophilic part.
What is an amphipathic molecule?
500
The type of reasoning is based on patterns and trends from specific observations. The conclusion is a possible extrapolation of the facts.
What is inductive reasoning?
500
This property of elements causes some covalent bonds to be polar (unequal electrons being shared), ionic bonding, and molecules to be polar.
What is electronegativity?
500
These molecules combust, are molecules of life, and have a carbon backbone.
What is an organic compound?
500
Nucleotides are inserted or deleted (not in multiples of 3) in a DNA sequence.
What is a frameshift mutation?
500
This level of protein structure consists of alpha helices and beta sheets, determined by hydrogen bonding.
