What is the term used to describe the variation in the genetic makeup of a population?

  1. Genetic diversity

  2. Genetic variation

  3. Genetic polymorphism

  4. Genetic drift


Correct Option: A
Explanation:

Genetic diversity refers to the variation in the genetic makeup of a population. It is the result of mutations, genetic recombination, and gene flow.

Which of the following is not a benefit of genetic diversity?

  1. Increased resistance to pests and diseases

  2. Increased adaptability to changing environmental conditions

  3. Increased productivity

  4. Increased susceptibility to pests and diseases


Correct Option: D
Explanation:

Genetic diversity is generally associated with increased resistance to pests and diseases, increased adaptability to changing environmental conditions, and increased productivity. Increased susceptibility to pests and diseases is not a benefit of genetic diversity.

What is the term used to describe the process by which genetic material is transferred from one organism to another?

  1. Gene transfer

  2. Genetic engineering

  3. Recombinant DNA technology

  4. Transgenesis


Correct Option: A
Explanation:

Gene transfer is the process by which genetic material is transferred from one organism to another. It can occur naturally through processes such as sexual reproduction and viral infection, or it can be induced artificially through techniques such as genetic engineering and recombinant DNA technology.

Which of the following is not a technique used in genetic engineering?

  1. Restriction enzyme digestion

  2. DNA ligation

  3. Polymerase chain reaction (PCR)

  4. Southern blotting


Correct Option: D
Explanation:

Restriction enzyme digestion, DNA ligation, and polymerase chain reaction (PCR) are all techniques used in genetic engineering. Southern blotting is a technique used in molecular biology to detect specific DNA sequences in a DNA sample.

What is the term used to describe an organism that has been genetically modified to contain genes from another organism?

  1. Transgenic organism

  2. Genetically modified organism (GMO)

  3. Recombinant organism

  4. Cloned organism


Correct Option: A
Explanation:

A transgenic organism is an organism that has been genetically modified to contain genes from another organism. This can be done through techniques such as gene transfer and genetic engineering.

Which of the following is not a potential risk of genetically modified organisms (GMOs)?

  1. Allergenicity

  2. Antibiotic resistance

  3. Gene transfer to wild populations

  4. Increased susceptibility to pests and diseases


Correct Option: D
Explanation:

Allergenicity, antibiotic resistance, and gene transfer to wild populations are all potential risks of genetically modified organisms (GMOs). Increased susceptibility to pests and diseases is not a potential risk of GMOs.

What is the term used to describe the process by which stem cells are differentiated into specific cell types?

  1. Stem cell differentiation

  2. Cell fate determination

  3. Transdifferentiation

  4. Dedifferentiation


Correct Option: A
Explanation:

Stem cell differentiation is the process by which stem cells are differentiated into specific cell types. This process is essential for the development of tissues and organs.

Which of the following is not a type of stem cell?

  1. Embryonic stem cells

  2. Adult stem cells

  3. Induced pluripotent stem cells (iPSCs)

  4. Cancer stem cells


Correct Option: D
Explanation:

Embryonic stem cells, adult stem cells, and induced pluripotent stem cells (iPSCs) are all types of stem cells. Cancer stem cells are not stem cells in the traditional sense, but they are a type of cell that is thought to be responsible for the initiation and progression of cancer.

What is the term used to describe the process by which a cell divides into two identical daughter cells?

  1. Mitosis

  2. Meiosis

  3. Binary fission

  4. Budding


Correct Option: A
Explanation:

Mitosis is the process by which a cell divides into two identical daughter cells. This process is essential for the growth and development of organisms.

Which of the following is not a phase of mitosis?

  1. Prophase

  2. Metaphase

  3. Anaphase

  4. Telophase


Correct Option: D
Explanation:

Prophase, metaphase, and anaphase are all phases of mitosis. Telophase is a phase of meiosis, not mitosis.

What is the term used to describe the process by which a cell divides into four haploid daughter cells?

  1. Mitosis

  2. Meiosis

  3. Binary fission

  4. Budding


Correct Option: B
Explanation:

Meiosis is the process by which a cell divides into four haploid daughter cells. This process is essential for sexual reproduction.

Which of the following is not a phase of meiosis?

  1. Prophase I

  2. Metaphase I

  3. Anaphase I

  4. Telophase I


Correct Option: D
Explanation:

Prophase I, metaphase I, and anaphase I are all phases of meiosis. Telophase I is a phase of mitosis, not meiosis.

What is the term used to describe the process by which DNA is copied?

  1. Replication

  2. Transcription

  3. Translation

  4. Mutation


Correct Option: A
Explanation:

Replication is the process by which DNA is copied. This process is essential for the growth and development of organisms.

Which of the following is not a type of DNA replication?

  1. Conservative replication

  2. Semiconservative replication

  3. Dispersive replication

  4. Rolling circle replication


Correct Option: C
Explanation:

Conservative replication, semiconservative replication, and rolling circle replication are all types of DNA replication. Dispersive replication is not a type of DNA replication.

What is the term used to describe the process by which DNA is transcribed into RNA?

  1. Replication

  2. Transcription

  3. Translation

  4. Mutation


Correct Option: B
Explanation:

Transcription is the process by which DNA is transcribed into RNA. This process is essential for the production of proteins.
