g A linear fragment of DNA is 30kb in length. It was subjected to digestion by Pst1, which resulted in 17, 9, 3, 1 kb fragments. The same DNA fragment is digested with EcoRV to get 12, 9, 5, 4 kb fragments. In a double digest with both enzymes, the following fragments sizes were observed; 8, 7, 5, 4 , 3, 2, 1kb fragments. Determine the order of the restriction sites.

the answer would be 2, if crossing over doesn’t occur 2 out of 4 of the daughter cells will have that allele.

hope this : )

those characteristics are cellular organization, reproduction, metabolism, homeostasis, heredity, response to stimuli, growth and development, and adaptation through evolution. some things, such as a virus, demonstrate only a few of these characteristics and are, therefore, not alive
