Question

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)
Responses

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

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

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.

Answer 1

The best option that describes how a liver cell and 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 is because, although both cells contain the same DNA, they express different sets of genes, leading to the production of different proteins, which in turn determines their structure and function.
