Protein Structure & Function
A specific characteristic controlled by genes.
What is a Trait?
The passing of traits from parents to offspring.
What is inheritance?
Having two identical gene versions.
Homozygous
Instructions for making proteins.
Genes
A physical or observable characteristic of an organism.
Traits/Phenotype
Differences in traits among individuals.
What is variation?
The type of reproduction that involves two parents.
What is sexual reproduction?
Having two different gene versions.
Heterozygous
Each of these provides instructions for a specific protein.
Gene Versions
Traits depend on the proteins found in these.
Cells
Changes in protein structure can lead to changes in these
What is traits?
Each parent passes on this many gene copies per feature.
What is one?
This produces only one type of protein.
Homozygous
An organism has this many copies of each gene.
2
Different protein interactions can cause this among organisms.
Variation
This determines how a protein molecule works.
What is a Structure?
This explains why siblings can have different traits.
What is random inheritance?
This produces two types of protein.
Heterozygous
Different versions of a gene can make different proteins.
Gene versions
Eye color and height are examples of this.
Traits
Protein molecules interact with other proteins to carry out this.
What is a
Gene versions are passed randomly during this process.
What is sexual reproduction?
A heterozygous organism gets these from parents
Different Gene Versions
A change in a gene that may change protein structure.
Mutation
Traits are determined by protein structure and these inside cells.
