2026 Updated.
5 core concepts - Answer -information flow
-structure function
-energy transformation
-evolution
-systems
amino acid polarity - Answer
electronegativities of organic atoms - Answer C~H<N<O
How to tell if a molecule is hydrophobic or hydrophilic - Answer Non-polar: hydrophobic
Polar: hydrophilic
Types of bonds and stored potential energy - Answer High to low
Covalent bonds:
peptide
disulfide bridge:
Ionic Bonds:
Hydrophobic interactions:
Hydrophilic interactions:
H bonds
molecular genotype + phenotype - Answer genotype: order of nucleotides
phenotypes: proteins produced and their traits
DNA - Answer A complex molecule containing the genetic information that makes up the
chromosomes.
, protein - Answer Made from 3 nucleotides, from tRNA in the ribosome
allele - Answer one of a number of different forms of a gene on the same place on the
chromosome
genome - Answer All the genetic information in an organism; all of an organism's
chromosomes.
metabolic pathway - Answer Begins with a specific molecule, which is then altered in a series
of defined steps, resulting in a certain product.
nucleotide - Answer A building block of DNA, consisting of a five-carbon sugar covalently
bonded to a nitrogenous base and a phosphate group.
5' vs 3' - Answer - 5' will have an OH or phosphate group bound to C-5' of the sugar
- 3' will have an OH bound to C-3' of the sugar
ribose vs. deoxyribose - Answer -ribose: has an -OH group at C-2
-deoxyribose: has an -H group at C-2
phosphate group - Answer A functional group consisting of a phosphorus atom covalently
bonded to four oxygen atoms
guanine, cytosine, thymine, adenine, uracil - Answer GCTAU, chemical bases of nucleotides
GC bonds are stronger than AU bonds
ATP - Answer (adenosine triphosphate) main energy source that cells use for most of their
work
affinity - Answer attraction between two biological molecules, to bind, modify, or destroy
template vs non-template strand - Answer template strand: strand on DNA moving towards 5'
