Detailed explanation-1: -Although all cells contain the same DNA sequence, muscle cells are different from nerve cells and other types of cells because of the different genes that are turned on in these cells and the different RNAs and proteins produced.
Detailed explanation-2: -Even though the cells in different types of tissue (e.g. muscle cells and liver cells) carry out very different tasks, they still contain the same genetic information that was passed on from the very first cell.
Detailed explanation-3: -Gene regulation is an important part of normal development. Genes are turned on and off in different patterns during development to make a brain cell look and act different from a liver cell or a muscle cell, for example. Gene regulation also allows cells to react quickly to changes in their environments.
Detailed explanation-4: -Answer and Explanation: Muscle cells and liver cells will not transcribe the same genes.
