  1. Genetic Engineering

  2. Molecular Breeding

  3. Gene Therapy

  4. Transgenesis


Correct Option: D
Explanation:

Transgenesis is the process of introducing a gene from one organism into another organism's genome.

What is the primary goal of molecular breeding?

  1. To improve crop yield

  2. To create disease-resistant plants

  3. To enhance nutritional value

  4. All of the above


Correct Option: D
Explanation:

Molecular breeding aims to improve crop yield, create disease-resistant plants, enhance nutritional value, and introduce other desirable traits.

Which molecular marker technique is commonly used for identifying specific DNA sequences?

  1. RFLP

  2. RAPD

  3. AFLP

  4. SNP


Correct Option: A
Explanation:

RFLP (Restriction Fragment Length Polymorphism) is a molecular marker technique used for identifying specific DNA sequences.

What is the role of genetic transformation in molecular breeding?

  1. Introducing new genes into an organism

  2. Altering gene expression

  3. Creating transgenic plants

  4. All of the above


Correct Option: D
Explanation:

Genetic transformation involves introducing new genes into an organism, altering gene expression, and creating transgenic plants.

Which molecular breeding technique utilizes gene silencing to suppress gene expression?

  1. RNA interference

  2. Gene editing

  3. CRISPR-Cas9

  4. Gene knockout


Correct Option: A
Explanation:

RNA interference is a molecular breeding technique that uses small RNA molecules to suppress gene expression.

What is the term used for a plant that has been genetically modified to express a gene from another organism?

  1. Transgenic plant

  2. Genetically modified organism

  3. Recombinant plant

  4. Hybrid plant


Correct Option: A
Explanation:

A plant that has been genetically modified to express a gene from another organism is called a transgenic plant.

Which molecular breeding technique allows for precise editing of the genome?

  1. CRISPR-Cas9

  2. Gene editing

  3. Genome editing

  4. All of the above


Correct Option: D
Explanation:

CRISPR-Cas9, gene editing, and genome editing all refer to molecular breeding techniques that allow for precise editing of the genome.

What is the primary application of molecular markers in molecular breeding?

  1. Identifying genetic diversity

  2. Marker-assisted selection

  3. Interspecific hybridization

  4. All of the above


Correct Option: D
Explanation:

Hybridization, crossbreeding, and interspecific hybridization all involve crossing two genetically different individuals to produce offspring with desired traits.

What is the term used for a plant that has been genetically modified to resist a specific pest or disease?

  1. Transgenic plant
