Answer to Question 1

Ans: A
Feedback:
Transcription is the process by which DNA sequences are copied into ribonucleic acid (RNA). Translation is the process by which information in RNA produces strings of amino acids, which in turn make up proteins (life's building blocks). Combinations of genetic parameters altered by environmental influences over time are referred to as the phenotype. Each gene has a specific location on the chromosome called an allele.

Answer to Question 2

Ans: B
Feedback:
Norepinephrine is implicated in mood disorders. Dopamine is implicated in schizophrenia; gamma-aminobutyric acid (GABA) is implicated in dementia, schizophrenia, and anxiety disorders; and high levels of serotonin are implicated in anxiety disorders.
