If you mix the pattersonase gene sequence with ecori, how many
fragments will you end up with? how long will the be?

One EcoRI site can be found in 4096 bp.As EcoRI can not cut a sequence if it is not complete, so 732421 recognition sites in human genome can be found. As you know human genome is linear genome, and when you digest it with Restriction Endonuclease having one recognition site, it always gives two fragments.

Explanation: (Idek how to explain it tbh..sorry :C )

the sun's light combined with the visible wavelenghts form what is called ultraviolet radiation, which are the long waves at the end of a visible light sprectrum.

hope it ,
