Questions and Answers
Five Pieces of evidence the might be obtained at a crime scene? - Correct Answers -
fingerprints, shoe prints, DNA, blood stains, and weapons
The relationship between DNA, chromosomes, nucleotides, and genes: - Correct
Answers -a chromosome is folded up DNA. DNA has a double helix form, and sections
of DNA are called genes. Genes are made up of many nucleotides.
Endocrine system - Correct Answers -produces hormones. Responsible for insulin and
glucogen
Cardiovascular system - Correct Answers -transport for blood, hormones, and nutrients
in the body. Blood vessels can be harmed if there are high blood glucose levels.
Urinary system - Correct Answers -dumps waste found in blood and regulates blood

Nervous system - Correct Answers -processes information and sends the brain
messages of what's going on in and outside of your vessel. High blood glucose can lead
to damaged nerves over time.
Parts of a nucleotide: - Correct Answers -deoxyribose sugar, phosphate, and nitrogen
base
The four bases of DNA: - Correct Answers -guanine-cytosine & thymine-adenine
Which base is not present in RNA? - Correct Answers -thymine isn't and is replaced w/
uracil
The job of restriction enzymes: - Correct Answers -to cut DNA at specific sequences
What does gel electrophoresis do? - Correct Answers -separates DNA based on size
Which way does DNA run on the gel? - Correct Answers -it runs down the gel, towards
the positive end.
