Which of the following best explains why cells that contain the same genetic material do not develop into the same types of cells? A. Because internal or external stimuli can trigger the activation of specific genes in the DNA of cells B. Because random mutations can occur in the DNA of cells during early embryonic development C. Because messenger RNA is converted to transfer RNA when cell differentiation begins D. Because chemical signals that are released during the cell cycle can result in the linking of similar genes
Understand the Problem
The question is asking which option best explains why cells with the same genetic material differentiate into different cell types. It requires understanding of cellular differentiation and gene expression.
Answer
A. Because internal or external stimuli can trigger the activation of specific genes in the DNA of cells.
The final answer is A. Because internal or external stimuli can trigger the activation of specific genes in the DNA of cells.
Answer for screen readers
The final answer is A. Because internal or external stimuli can trigger the activation of specific genes in the DNA of cells.
More Information
Cells differentiate because specific genes are turned on or off in response to internal and external signals, leading to the development of different cell types from the same genetic material.
Tips
A common mistake is thinking all parts of the genetic material are always active. Remember, only specific genes are activated or repressed.
