Question

What is a genetically modified organism (GMO)? a. a plant with certain genes removed b. an organism with an artificially altered genome c. a hybrid organism d. any agricultural organism produced by breeding or biotechnology

Short answer

b. an organism with an artificially altered genome

Step-by-step solution

Eliminate the incorrect options

To find the correct answer, we will first evaluate each option to see if it accurately defines a GMO (genetically modified organism). Option a: a plant with certain genes removed - This definition is not broad enough, as GMOs are not limited to plants but can also include animals and microorganisms with specific genetic modifications. Option b: an organism with an artificially altered genome - This definition includes both plants and animals and suggests that changes have been made to the natural genome artificially. This option seems to be a good candidate for a correct answer. Option c: a hybrid organism - A hybrid organism is created through the natural process of sexual reproduction between two different species. While some GMOs might also be hybrids, not all hybrids are GMOs. Therefore, this option does not accurately define GMOs. Option d: any agricultural organism produced by breeding or biotechnology - This option includes all organisms produced by breeding, which encompasses both traditional breeding methods and genetic engineering. Since some organisms created through traditional breeding are not GMOs, this option is not an accurate definition for GMOs.

Select the correct option

Based on our analysis in Step 1, the most accurate definition for a genetically modified organism (GMO) is: b. an organism with an artificially altered genome

Key concepts

Artificially Altered Genome

An artificially altered genome refers to changes made to an organism's DNA using technology rather than through natural methods. In this process, scientists use various techniques to modify specific genes within the DNA to achieve desired traits or characteristics.

The genome is the complete set of genes or genetic material present in a cell or organism. When these genes are artificially modified, it can lead to significant changes in how an organism develops, behaves, or interacts with its environment.

• Genetic material is edited, removed, or inserted.
• Techniques like CRISPR, gene splicing and recombinant DNA technology are used.
• The goal may be to enhance growth rates, resist diseases, or improve nutritional content.

By understanding how to artificially alter a genome, scientists can produce organisms that better meet human needs or solve specific problems.

Genetic Modification

Genetic modification is the process of altering the genetic material of an organism to change its characteristics. This can be done through several methods, but all involve making changes to the DNA sequence.

Common reasons for genetic modification include increasing resistance to pests and diseases, improving nutritional value, or enabling production of pharmaceuticals.

• Can target specifics like drought resistance in plants or faster growth in animals.
• Involves techniques like gene cloning and transferring genes between species.
• Helps in adapting crops to changing climates or enhancing yield.

Through genetic modification, we can address challenges in agriculture, medicine, and industry, providing innovative solutions by directly changing genetic information.

Biotechnology

Biotechnology is the application of biological processes for technological advancement and innovation. It involves using living organisms, their parts, or systems to develop new products and processes that benefit society.

This field encompasses a wide range of applications, from healthcare and agriculture to environmental management and food processing.

• Includes genetic engineering, cell culture, and enzyme production.
• Has led to advances like the production of synthetic insulin and biofuels.
• Aims to use biological systems to find sustainable solutions.

By leveraging the power of biotechnology, we can create efficient, ethical, and sustainable practices that improve quality of life and address global issues.

Organism Identification

Organism identification is the process of categorizing or naming an organism based on its anatomical, genetic, and morphological characteristics. This is essential in understanding and documenting biodiversity, and in contexts such as medicine and agriculture.

With advancements in genetic analysis, reliance on genomic data has become increasingly important.

• DNA barcoding is a common method for identifying species accurately.
• Can help track the movement of species, detect invaders, or monitor changes in ecosystems.
• Allows for precise identification and classification, which is crucial for conservation efforts.

Through organism identification, we can better manage natural resources, identify threats, and make informed decisions for environmental and public health.
