29 Questions
What is meiosis?
A process of cell division that produces genetically different offspring
When does meiosis occur?
During sexual reproduction
What is the purpose of cells dividing?
All of the above
In asexual reproduction, offspring are genetically identical to the parent because
They have only one parent
In sexual reproduction, offspring are genetically different from one another and from the parents because
They receive genetic information from two parents
What is the purpose of citing information sources?
To give credit to the original authors and avoid plagiarism
Which of the following is true about tumor suppressor genes?
They continuously survey cells for abnormalities
What are the three checkpoints in the cell cycle?
G1, G2, and Metaphase
What are proto-oncogenes?
Genes that code for the cell cycle control proteins
What happens during meiosis?
Homologous pairs of chromosomes separate into two cells
What is the difference between somatic cells and gametes?
Somatic cells have 46 chromosomes and gametes have 23 chromosomes
What is a karyotype?
A photograph of chromosomes arranged in pairs
What is crossing over in meiosis?
The exchange of genetic information between homologous chromosomes
During which phase of meiosis does crossing over occur?
Prophase I
What is the result of crossing over during meiosis?
Formation of new types of gametes
What is random alignment during meiosis?
Random arrangement and separation of different pairs of chromosomes
What is the impact of random alignment during meiosis?
Formation of genetically distinct gametes
What is the purpose of crossing over and random alignment during meiosis?
Increase the variation in individuals produced when gametes fuse
How many major organ systems are there in the human body?
11
What are the four basic types of tissue in the human body?
Epithelial, Connective, Muscle, Nervous
What is the definition of organs?
Structures composed of two or more tissue types working together for a specific function
How do all the organ systems in the body work together?
To help an organism function
Which of the following accurately describes the process of DNA replication?
DNA replication is a semiconservative process
What is the function of DNA polymerase in DNA replication?
DNA polymerase moves along the unwound DNA to form the new strands
Which of the following accurately describes the cell cycle?
The cell cycle consists of three steps: interphase, mitosis, and cytokinesis
What is the function of tumor suppressors in the cell cycle?
Tumor suppressors continuously survey cells for abnormalities
Which of the following accurately describes the process of mitosis?
Mitosis can be divided into four stages: prophase, metaphase, anaphase, and telophase
What is the purpose of cytokinesis in the cell cycle?
Cytokinesis is the division of the cytoplasm
What is the correct order of the phases of the cell cycle?
Interphase, mitosis, cytokinesis
