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.

Front

True or False: Genetic variation and environmental factors influence gene expression.

Back

True

Front

True or False: Gene expression is solely determined by genes and is not impacted by the environment.

Back

False

Front

What factors can influence gene expression?

Back

Both genetic variation and environmental factors.

Front

How can environmental factors affect gene expression?

Back

By altering how a gene is expressed.

Front

What does genetic variation refer to?

Back

Differences in DNA sequences among individuals.

Front

What is the role of environmental factors in gene expression?

Back

Environmental factors can affect the timing, location, and level of gene expression.

Front

Give an example of a genetic variation that can influence gene expression.

Back

Single nucleotide polymorphisms (SNPs) can lead to differences in how genes are expressed.

Front

What is epigenetics?

Back

Epigenetics is the study of changes in gene expression that do not involve alterations to the underlying DNA sequence.

Front

How can lifestyle choices impact gene expression?

Back

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