Biochemistry WGU C785 - Module 1
Hydrophilic
Correct Answer: Having an affinity for water.

Hydrophobic
Correct Answer: substances that are not soluble in water. Hydrophobic substances include large,
uncharged particles like fats and oils

solvent
Correct Answer: A liquid substance capable of dissolving other substances

Solute
Correct Answer: A substance that is dissolved in a solution.

Adhesive
Correct Answer: Having the ability to stick to other surfaces.

Cohesive
Correct Answer: having the ability to stick together

Heat of Vaporization
Correct Answer: The amount of energy required for the liquid at its boiling point to become a gas

Anticodon
Correct Answer: Three-base sequence in a transfer RNA molecule base that pairs with a
complementary codon in mRNA

Central Dogma of Molecular Biology
Correct Answer: DNA -> RNA -> Protein

This paradigm was formulated by Grancis Crick: First, a portion of the DNA, a gene, is transcribed to
produce a complementary strand of RNA; then RNA is translated into protein

Codon
Correct Answer: A specific sequence of three adjacent bases on a strand of DNA or RNA that
provides genetic code information for a particular amino acid

DNA
Correct Answer: deoxyribonucleic acid, a self-replicating material present in nearly all living
organisms as the main constituent of chromosomes. It is the carrier of genetic information.

Dominant Allele
Correct Answer: an allele that dominates or masks the presence of another allele and is fully
expressed

Dominant trait
Correct Answer: the trait that is expressed from a dominant allele
