27 Questions
What is the main reason for mitosis to result in identical daughter cells?
To ensure each daughter cell has a complete set of chromosomes
In which phase of the cell cycle does DNA replication occur?
S phase
During which stage of mitosis do the sister chromatids separate and move towards opposite poles of the cell?
Anaphase
How does cytokinesis differ between animal and plant cells?
Animal cells undergo cleavage while plant cells form a cell plate
What causes a cell to grow uncontrollably?
Unregulated cell division
What is the primary difference between benign and malignant tumors?
Malignant tumors can invade surrounding tissues while benign tumors cannot
What term describes the genetic inheritance pattern where one allele is fully expressed, masking the effect of the other allele?
Codominance
Which term refers to a type of gene interaction where the phenotype of the heterozygote is distinct from and often intermediate to the phenotypes of the homozygotes?
Incomplete dominance
Why do sex-linked diseases appear more commonly in male humans?
Males have one X chromosome and one Y chromosome.
What term describes the process of creating recombinant DNA?
Recombination
What is the term for a heritable change in the genetic material, leading to genetic diversity?
Mutation
What is the term for a heritable change in the genetic material?
Mutation
What refers to the process of creating recombinant DNA?
Genetic engineering
During which step does the separation and movement of sister chromatids occur in the cell?
Mitosis
What term describes the events that occur during each step of DNA replication, transcription, and translation?

What does natural selection account for in the process of evolution?
Genetic diversity
What is the term for a gene interaction where the phenotype of the heterozygote is distinct from and often intermediate to the phenotypes of the homozygotes?
Incomplete dominance
Which mechanism of evolution involves the movement of genes between populations, leading to a reduction in genetic differences?
Gene flow
What is the term for the process of creating new species due to geographic isolation?
Allopatric speciation
What is the main evidence for the theory of evolution found in the fossil record?
The existence of transitional fossils
Which term describes the concept of organisms sharing a common ancestor and being classified based on their evolutionary relationships?
Phylogeny
In the geologic time scale, which era is characterized by the dominance of dinosaurs and the appearance of flowering plants?

What is the term for the process by which a single species evolves into diverse forms occupying different ecological niches?
Adaptive radiation
What type of reproductive barrier prevents mating or fertilization between species due to differences in behavior or timing?

Which evolutionary pattern involves long periods of little change followed by rapid bursts of speciation?
Punctuated equilibrium
Which domain includes organisms with prokaryotic cells and is further divided into Archaea and Bacteria?
Archaea
What is the ecological significance of prokaryotes?
All of the above
This quiz covers the necessity of identical daughter cells in mitosis, events in each phase of the cell cycle and mitosis, differences between cytokinesis in animal and plant cells, uncontrollable cell growth, and the relationship between cancer and cell cycle, mitosis, tumors, and metastasis.
