Gene Expression Flashcard

Front

What is gene expression?

Back

Gene expression is the process by which information from a gene is used to synthesize a functional gene product, typically proteins, which perform various functions in the cell.

Why is it important to study genetic variation in gene expression?

Back

Studying genetic variation helps us understand how different genetic makeups can lead to variations in traits and responses to environmental factors.

Front

What role do environmental factors play in gene expression?

Back

Environmental factors can influence the regulation of gene expression, affecting how genes are turned on or off in response to external stimuli.

Front

What is the relationship between genetic variation and environmental factors?

Back

Genetic variation and environmental factors interact to influence gene expression, which can affect an organism's phenotype.

Front

True or False: Gene expression is solely determined by genes.

Back

False. Gene expression is influenced by both genetic and environmental factors.

Front

What is the significance of understanding gene expression in human health?

Back

Understanding gene expression is essential for studying human health and disease, as it helps identify how genes contribute to health conditions.

Front

What are some examples of environmental factors that can influence gene expression?

Back

Examples include temperature, nutrition, toxins, and stress.

Front

What is the concept of epigenetics?

Back

Epigenetics refers to changes in gene expression that do not involve alterations to the underlying DNA sequence, often influenced by environmental factors.

Front

How can studying gene expression lead to therapeutic interventions?

Back

By understanding how genes are expressed in diseases, researchers can identify potential targets for new treatments.

Front

What is a phenotype?

Back

A phenotype is the observable physical or biochemical characteristics of an organism, determined by both genetic and environmental factors.
