What is Not True of the Five Different Cell Types

Question

What is not true of the five different cell types from the individual shown in the figure below? 
A)They have the same DNA sequence. 
B)They contain the same genes. 
C)They express the same genes at the same time. 
D)They have the same housekeeping genes.

Accepted Answer

The five different cell types from the individual shown in the figure below are likely to have different gene expression patterns, meaning that they do not necessarily express the same genes at the same time. Therefore, option C is false. On the other hand, options A, B, and D could be true since they do not rely on gene expression patterns. They all could differ in the epigenetic and post-transcriptional or post-translational regulation of gene expression, cell-specific functions, and other factors.
