If a population of rabbits with varying fur colors migrates into a snowy environment, which genetic concept explains the increase in frequency of alleles for white fur color over generations?
When comparing DNA and RNA molecules, which component varies to contribute to their functional differences?
The __ structure of amino acids allows for differentiation.
A mutation occurs such that a single nucleotide change creates a new restriction site recognized by enzyme Y within a non-coding region close to Gene X; how could this most directly affect evolutionary fitness?
In protein secondary structure formation, what kind of interaction stabilizes alpha-helices and beta-pleated sheets?
If a mutation occurs that significantly increases the efficiency of an enzyme responsible for a key step in a primary producer's metabolic pathway, what is the most likely immediate ecological impact?
What role does water play in contributing to the structure and stability of proteins at the molecular level?

Considering the principle that structure dictates function within biological macromolecules, what impact would a point mutation causing a change from hydrophilic to hydrophobic amino acid have on protein function?
In DNA, why does adenine always pair with thymine?
What outcome can be predicted if a keystone species that functions as an engineer (e.g., beavers) is removed from a wetland ecosystem?
