Atoms
Atoms are made of 3 subatomic particles. What are they?
Protons, neutrons, and electrons.
When you look at an element square, you can always see two numbers. These two numbers are...
The atomic mass and the atomic number.
Name at least 3 biomolecules we learned about in class.
Proteins
Nucleic Acids
Carbohydrates
Lipids
Name the 4 bases of DNA. You can use their letters or their full names.
Adenine, thymine, cytosine, guanine
Say something that you learned from this course that you didn't know before.

What is the most accurate way to draw an atom?
As nothing, or just as a fuzzy cloud.
The Periodic Table is supposed to organize elements based on their type. Most of the elements on the Periodic Table are...
Metals.
What does "monomer" mean?
A building block of something else, or a smaller part of something else.
What are the 2 main parts of DNA?
The bases and the backbone.
Basic Chemistry
Why are neutrons important?
Neutrons stabilize the nucleus of the atom and prevent the protons and electrons from chasing each other around.
An atom of nitrogen has 7 protons and its mass number is 14. How many neutrons does it have?
7.
Which biomolecule is simpler? A carbohydrate or a nucleic acid?
A carbohydrate. It's just a long chain of sugar.
Unwinding the DNA strands with helicase.
What is Sarah's major at school?
Biomedical Engineering
When we draw atoms, we draw them using the Bohr Model. The Bohr Model shows electrons in rings. If this isn't accurate, why do we draw atoms like this?
To make it easier to read, to show people which atoms we're talking about, and because it is more organized.
They are the alkali metals. They are very reactive.
Proteins.
What is the matching strand to this line of DNA?
ATGTCCA
TACAGGT
What are the 3 choices for review games in the course?
The most important aspect of about an atom is its atomic number. Why?
Because the atomic number is the number of protons, and the number of protons decides which element it is.
What happens to the elements' size as we move down a column in the Periodic Table?
They get bigger.
We don't need to worry about getting enough nucleic acids in our diet. Why?
Because we get them whenever we eat something that was alive.
Positive factors make genes easy to express.
Negative factors make them hard to express.
Recall your favorite day of the course and explain why it was your favorite day.
