Sample Question
For a couple of decades, biologists knew the nucleus contained DNA and proteins. The prevailing opinion was that the genetic material was proteins, and not DNA. The reason for this belief was that proteins are more complex than DNA. This is because

Proteins have a greater variety of three-dimensional forms than does DNA.

Proteins have two different levels of structural organization; DNA has four.

Proteins are made of 20 amino acids and DNA is made of four nucleotides.

Only A and C are correct.

A, B, and C are correct.

Sample Question
What does it mean for a trait to be dominant?

Dominant traits are always physically stronger than recessive traits.

A dominant trait will always express itself in an organism whether it is partnered with a different (recessive) trait or with another dominant partner. For example: The tallness trait in peas can be recognized as "A" which is dominant and the recessive shortness can be recognized as "a" "AA" will result in a tall pea as will "Aa"

An organism can have multiple dominant traits at the same time.

A dominant trait will only express itself if it is partnered with another dominant trait.
