Informative. I used to be clueless about the process but now i have an idea.

#3 - That is the correct answer to the question in the title, sir.
Now THIS educational SnotR video is way more interesting!

Well, you dont really put together the "book" you just shredded. You put together the data gathered from it. If you were to be able to put the "book" back together in its physical form, it would be quite amazing. But dont see that happening any time soon. The next step in that process would be to recreate something from "nothing".

The human genome is about 3,120,000,000 DNA base pairs long, so half of that is in each spermatozoa. That gives us 1,560,000,000 base pairs in a single sperm cell.
Each of those base pairs can be an A-T bond or a G-C bond, and can be aligned in either direction. That means there's 4 ways it ca be aligned, and that can be represented in two bits of data: 00 = G, 01 = C, 10 = A, and 11 = T, for example.
Now the average SNOTR dude lets out between 50-500 million sperm with each go. Rough average says that it be probably be about 200 million, right? If we take all this information and combine it with the wonders of mathematics, we have 1 560 000 000 x 2 bits x 200 000 000 = 624 000 000 000 000 000 000 bits, which is transmitted in a single burst.
Thats 78 000 terrabytes, in what amounts to half-minute at most event. So your rooster has a higher bandwidth the worlds internet connection. Imagine you have a machine that uses your baby maker to surf the net, well ofc your just gonna use that to surf for porn.

This is what I do Very well done video, its easier and more efficient to explain in lectures but that figures. Thanks for the upload now I can use this as an answer when I'm lazy
#13 These comparisons are well ok but when you say a spermatocyte has half of our genome dont confuse people, it only has one chromosome set due to prior meiosis but one is all you need as everything from one person is on there. you dont have to sequence both as they are identical if no error is present.

#7 That's true in many cases, but it is possible to corrupt potential evidence, rendering it useless to a forensic lab, if you know some rather simple chemistry. Knowledge is a double edge sword.
