Which of the following best describes how a liver cell and skin cell have the exact same DNA sequence and yet look different and perform different functions? (1 point)

Question

• The tRNA uses a different sequence in each cell during transcription.
• The cells discard the DNA that is not in use.
• The cells mutate during transcription.
• The proteins are expressed differently in each cell.

Answer 1

The best description for how a liver cell and skin cell can have the same DNA sequence yet look and function differently is:

• The proteins are expressed differently in each cell.

This means that although both cells contain the same DNA, they activate different sets of genes, leading to the production of different proteins that ultimately determine their distinct structures and functions.
