Question

Responses

The proteins are expressed differently in each cell.
The proteins are expressed differently in each cell.

The tRNA uses a different sequence in each cell during transcription.
The tRNA uses a different sequence in each cell during transcription.

The cells discard the DNA that is not in use.
The cells discard the DNA that is not in use.

The cells mutate during transcription.
The cells mutate during transcription.

Answer 1

The best description of how a liver cell and a skin cell can have the exact same DNA sequence and yet look different and perform different functions is:

The proteins are expressed differently in each cell.

This means that while the DNA is the same, different genes are turned on or off in each type of cell, leading to the production of different proteins, which in turn leads to different cell structures and functions.
