Gene Expression Flashcard

Front

Gene expression is a ____________ process!

Back

regulated

Front

Which modification leads to an increase in the rate of transcription?

Back

acetylation of histone proteins

Front

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

Back

False

Front

What is gene expression regulation?

Back

Gene expression regulation is important in biology because it allows cells to respond to their environment, differentiate into specific cell types, and maintain proper functioning of the organism.

Front

How does genetic variation contribute to individual differences in response to environmental factors?

Back

By causing different responses to the same environmental factor.

Front

Define gene expression.

Back

The process by which information from a gene is used to synthesize a functional gene product, usually a protein.

Front

What role do transcription factors play in gene expression?

Back

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

Front

What is the significance of DNA methylation in gene expression?

Back

DNA methylation can repress gene expression and is a key mechanism in regulating gene activity.

Front

Explain the term 'operon'.

Back

An operon is a cluster of genes under the control of a single promoter, functioning together in a coordinated manner.

Front

What is the difference between transcription and translation?

Back

Transcription is the process of copying a segment of DNA into RNA, while translation is the process of synthesizing proteins from RNA.
