BIOC 301 Exam 1 and Answers
Biochemistry - Answers✓✓The application of chemistry to the study of biological processes at
the cellular and molecular level
Central dogma - Answers✓✓Self-replicating DNA undergoes unidirectional transfer to
messenger RNAs in transcription which act as templates for protein synthesis in translation
DNA - Answers✓✓Genetic information storage of all life (exception of some viruses).
Deoxyribonucleic acid. Instructions to direct synthesis of RNA and DNA
Atmosphere of early earth - Answers✓✓H2, CH4, NH3, HCN, H2O, some CO and CO2
Miller-Urey experiment result - Answers✓✓Showed under conditions of early earth building
blocks like amino acids can arise
Evolution - Answers✓✓The ability to make a copy and retain information. Any improvement
to your system's ability to be reproduced is selected for and improved upon with each cycle
Polymerization reactions - Answers✓✓Reactions to create polymers of the basic building
blocks
RNA world hypothesis - Answers✓✓A hypothetical stage in the evolutionary history of life of
Earth in which self-replicating RNA molecules proliferated before the evolution of DNA and
proteins

Hydrogen bond donor - Answers✓✓The atom to which the hydrogen atom participating in the
hydrogen bond is covalently bonded (NOF)
Hydrogen bond acceptor - Answers✓✓The atom of a hydrogen bond which does not supply the
hydrogen atom
Rate of breaking and forming hydrogen bonds in water - Answers✓✓1-20 picoseconds
Average hydrogen bonds per water molecule - Answers✓✓3.4
Hydrophobic effect - Answers✓✓The ability of water to push together nonpolar molecules.
Due to increase in entropy.
