Question

Which of the following best describes how a blood cell and skin cell have the exact same DNA sequence and yet

look different and perform different functions? (1 point)
O The proteins are expressed differently in each cell.
O The tRNA uses a different sequence in each cell during transcription
The cells discard the DNA that is not in use.
O The cells mutate during transcription

Answer 1

The proteins are expressed differently in each cell.

Step-by-step explanation:

The correct answer would be that the proteins are expressed differently in each cell.

The regulation of gene expression is primarily responsible for differential functions of the same DNA sequence. Multiple proteins are formed from the same DNA sequence but only the required ones are specifically expressed depending on the cell.

In other words, in the blood cells, the protein is expressed for performing blood-specific functions while it is expressed for performing skin-specific functions in the skin.
