What is the role of DNA in the reproduction process?
What is the role of DNA in the reproduction process?
- DNA in the cell nucleus is used as a template for making proteins (correct)
- DNA controls the separation of chromosomes during reproduction
- DNA is responsible for creating additional cellular apparatus
- DNA ensures absolute identical copies of cells during reproduction
Why would simply pushing out one copy of DNA during reproduction not work?
Why would simply pushing out one copy of DNA during reproduction not work?
- The copy pushed out lacks organized cellular structure for maintaining life processes (correct)
- Pushing out DNA would cause the cell to divide incorrectly
- Separated DNA copies would not be similar to the original DNA
- Pushing out DNA can lead to drastic variations in the new cell
How does variation in DNA copies during reproduction contribute to evolution?
How does variation in DNA copies during reproduction contribute to evolution?
- Variation creates subtly different surviving cells from each other (correct)
- Variation ensures survival of all new cells produced
- Variation prevents any changes in offspring from generation to generation
- Variation leads to absolutely identical new cells
