Below are sample questions representative of the exercises included on this worksheet and related 7.44 Genes, Chromosomes, and Deoxyribonucleic Acid Structure and Function skill assessments:

Problem 1Difficulty: Mastery
A planned final review image offers four complete models. Which model should a teacher choose because it best shows the relationships among DNA, genes, chromosomes, proteins, and traits?
AA model with proteins creating chromosomes and DNA
BA model with traits inside proteins inside genes
CA model with one chromosome containing a DNA molecule, several gene segments on that DNA, and arrows from a gene to a protein to a trait
DA model with traits making genes directly
Solution & Explanation:This model best represents the correct structural relationships and the pathway from gene information to trait.
Problem 2Difficulty: Mastery
Which question could a strong heredity model answer best?
AHow does sound travel through air?
BHow far away is the Sun from Earth?
CHow many countries are in South America?
DHow can a change in a gene on a chromosome lead to a change in a protein and then a trait?
Solution & Explanation:A heredity model is designed to explain how gene changes can affect proteins and traits.
Problem 3Difficulty: Mastery
A student says, 'If two organisms share a trait, they must have exactly the same DNA everywhere.' What is the best rebuttal?
ASharing one trait can happen even when organisms have many other DNA differences.
BProteins cannot influence traits.
CTraits are not related to genes at all.
DDNA exists only in organisms that look different.
Solution & Explanation:A shared trait does not mean two organisms have identical DNA in every gene.
