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 a protein.

Front

What factors can influence gene expression?

Back

Both genetic variation and environmental factors can influence gene expression.

Why is it important to study gene expression in relation to human health?

Back

Studying gene expression helps us understand how genetic and environmental factors contribute to health and disease.

Front

How do environmental factors affect gene expression?

Back

Environmental factors can affect gene expression by altering how genes are expressed, such as through epigenetic modifications.

Front

What is genetic variation?

Back

Genetic variation refers to the differences in DNA sequences among individuals, which can affect traits and gene expression.

Front

What role do epigenetics play in gene expression?

Back

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

Front

Can gene expression be influenced by lifestyle choices?

Back

Yes, lifestyle choices such as diet, exercise, and exposure to toxins can influence gene expression.

Front

What is the relationship between gene expression and disease?

Back

Altered gene expression can lead to diseases, as it may disrupt normal cellular functions and processes.

Front

What is the significance of studying both genetic and environmental factors in gene expression?

Back

Studying both factors provides a comprehensive understanding of how they interact to influence health outcomes.

Front

What is a transcription factor?

Back

Transcription factors are proteins that help regulate the transcription of specific genes by binding to nearby DNA.
