Define Interphase in the context of the cell cycle.

Back

Interphase is the stage where the cell spends most of its time, preparing for division.

Front

What is a codon?

Front

What is the difference between genotype and phenotype?

Back

Genotype refers to the genetic makeup, while phenotype refers to the observable traits.

Front

What is a mutation?

Back

A mutation is a change in the DNA sequence that can lead to changes in phenotype.

Front

What is the role of feedback loops in biological systems?

Back

Feedback loops help maintain homeostasis by regulating biological processes.
