How does gene expression differ between muscle cells and nerve cells?

Both muscle and nerve cells express genes for neurotransmitter production.

Muscle cells and nerve cells express the same genes but in different quantities.

Gene expression in muscle and nerve cells is identical, but protein folding differs.

Muscle cells express genes related to contraction, while nerve cells express genes related to neurotransmission.

Verified step by step guidance

Understand that gene expression refers to the process by which information from a gene is used to synthesize a functional gene product, usually a protein.

Recognize that different cell types, such as muscle cells and nerve cells, have distinct functions and therefore express different sets of genes to fulfill their roles.

Muscle cells are specialized for contraction and movement, so they express genes that produce proteins like actin and myosin, which are essential for muscle contraction.

Nerve cells, or neurons, are specialized for transmitting signals, so they express genes that produce proteins involved in neurotransmission, such as neurotransmitter receptors and ion channels.

While both muscle and nerve cells may share some common genes, the key difference lies in the specific genes that are expressed to support their unique functions, with muscle cells focusing on contraction-related genes and nerve cells on neurotransmission-related genes.
