What is the process by which cells specialize during embryonic development?

Back

Differentiation

Front

What is gene expression?

Back

The ability for a gene to be transcribed.

Front

What can affect the health of an organism's children and grandchildren through inherited mechanisms?

Back

Epigenetic tags.

Front

What is epigenetic inheritance?

Back

Inheritance NOT involving the nucleotide sequence of the DNA but involving chromatin modifications such as methylation.

Front

How can muscle cells and nerve cells have the same DNA sequences but perform different functions?

Back

The proteins expressed in each cell are different.

Front

What are epigenetic tags?

Back

Chemical modifications that affect gene expression without altering the DNA sequence.

Front

What role does methylation play in gene expression?

Back

Methylation can silence gene expression.

Front

What is the significance of differentiation in multicellular organisms?

Back

It allows for the development of specialized cells with distinct functions.

Front

How does environmental stress influence epigenetic changes?

Back

Environmental stress can lead to modifications in epigenetic tags that affect gene expression.

Front

What is the difference between transcription and translation in gene expression?

Back

Transcription is the process of copying DNA to RNA, while translation is the process of synthesizing proteins from RNA.
