What question did the discovery of the replication mechanism of DNA answer? AND How are the two new DNA copies like the original DNA?

according to Watson and Krick hypothesis that repilication of DNA is semiconservative >> this sequence will act as template to complementary other that each one cell division will separate each strand and do to one cell

1. How is genetic information passed to daughter cells and to the next generation?

2. The two new DNAs are exactly like the original DNA. The original splits apart, and the sides act as patterns for the formation of the new complementary strands. The strands serve as templates for the new molecules. This is referred to as "semiconservative" because half of the original molecule is in each of the new molecules.

I would have to say the biggest question it answers is: Where does the extra DNA come from when a cell divides?

The two new copies each have a template strand (from the original DNA double helix) along with the daughter strand (strand replicated). So essentially when a cell divides, it donates one of its strands and makes a new one.
