Assessment Packet - DNA & Proteins Unit

The traits of an organism are determined by:

• its environment

• its diet

• its genes

• its behavior

Traits are inherited from parents through:

• genetic inheritance

• environmental factors

• learned behavior

• random chance

Can we predict traits?

• Yes, we can predict traits using genetic information.

• No, traits cannot be predicted at all.

• Traits can only be predicted in certain conditions.

• Traits prediction is purely speculative.

How does DNA determine the observable traits of living organisms?

• By encoding genetic information that guides protein synthesis

• By directly interacting with environmental factors

• By altering the chemical composition of cells

• By influencing the gravitational forces on cells

DNA stores information. It has sugars and bases. The order of sugars and bases determines the traits. What does DNA store?

• Information

• Sugars

• Bases

• Traits

Traits are used to classify different species from each other. How do these traits relate to cells, DNA, and proteins?

• Traits are determined by DNA, which codes for proteins that form cells.

• Traits are unrelated to DNA, cells, and proteins.

• Traits are only influenced by environmental factors.

• Traits are determined by proteins alone.

The primary purpose of DNA is to:

• Store genetic information

• Provide energy to cells

• Transport oxygen

• Regulate body temperature

Which three molecules are found in DNA and what is the purpose of each?

• Deoxyribose sugar, phosphate group, nitrogenous bases; structural support, backbone formation, genetic coding

• Ribose sugar, phosphate group, nitrogenous bases; energy storage, backbone formation, genetic coding

• Deoxyribose sugar, sulfate group, nitrogenous bases; structural support, backbone formation, protein synthesis

• Ribose sugar, sulfate group, nitrogenous bases; energy storage, backbone formation, protein synthesis

What is a nucleotide? How does it relate to DNA and what DNA is made from?

• A nucleotide is a building block of DNA, consisting of a sugar, a phosphate group, and a nitrogenous base.

• A nucleotide is a type of protein that forms the structure of DNA.

• A nucleotide is a lipid molecule that is part of the DNA structure.

• A nucleotide is an enzyme that helps in the replication of DNA.

The molecules in DNA are similar to the components of a spiral notebook in that they both have a:

• double helix structure

• binding mechanism

• spiral shape

• set of instructions
