Answer:
DNA can be likened to a zipper. As with a zipper, the two DNA strands are connected by hydrogen bonds formed between nucleotides. When replication occurs, the twisting of the strands unravels, akin to opening a zipper. The strands separate, just as the teeth of a zipper do when it is unzipped. Each strand is capable of generating a new strand.
However, just like improper handling or wear can damage a zipper, DNA replication can also introduce errors that may result in mutations.
The meals will be fresher and more nutritious, but because they are fresh, the price will be higher, roughly around two dollars more compared to the cost of the less healthy meal.
