PLTW BIOMEDICAL SCIENCES - FINAL EXAM WITH CORRECT
ANSWERS #5
What is the relationship between DNA and genes? - correct answer A gene is a section
of a DNA molecule that contains the information to code for the specific protein.
What are the structural components of DNA? - correct answer Nucleotides
What are the structural components of a nucleotide? - correct answer Deoxyribose
sugar, Nitrogenous base, Phosphate group
What is the "A" base? What does it pair with? - correct answer Adenine; Thymine
What is the "T" base? What does it pair with? - correct answer Thymine; Adenine
What is the "C" base? What does it pair with? - correct answer Cytosine; Guanine
What is the "G" base? What does it pair with? - correct answer Guanine; Cytosine
Which bases are pyrimidines? - correct answer Cytosine and Thymine
Which bases are purines? - correct answer Adenine and Guanine
What is the shape of DNA described as? - correct answer Double helix
What is a restriction enzyme? - correct answer An enzyme used to cut DNA after its
recognition of specific nucleotide
What are the five manners of death? - correct answer Natural, Accident, Suicide,
Homicide, Undetermined
What are the two types of autopsies? - correct answer Forensic and Clinical
What is a forensic autopsy? - correct answer An autopsy performed to try and find the
cause of death for a police investigation
What is a clinical autopsy? - correct answer AN autopsy performed to determine the
cause of death for study purposes, usually performed in hospitals
