Biochemistry WGU C785 - Module 1
Exam 2026 Questions and Answers
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
Recessive allele - Correct answer-the trait that is completely masked and is not
expressed
Recessive trait - Correct answer-a genetic factor that is blocked by the presence of
a dominant factor
Epigenetics - Correct answer-the study of environmental influences on gene
expression that occur without a DNA change
Exons - Correct answer-expressed sequence of DNA; codes for a protein
