Answer to Question 1

B

Answer to Question 2

The latest microwave observations of the cosmic microwave background are sensitive enough to detect tiny temperature variations across the sky. These correspond to slight density enhancements at the end of the era of nuclei which magnified under the force of gravity to become the large scale structuresvoids, superclusters, etc.that we see at the present time. The present conditions of the universe are dependent on the structure of these initial density fluctuations, and for this reason it is analogous to the genetic code of DNA in a living organism.
