Answer #1

Answer:

The average size of the pieces formed by cutting the DNA with EcoR1 restriction enzyme: 4096 basepairs long

Recognition sequence of EcoR1: GAATTC

Frequency of EcoR1 site in a sequence of nucleotide: for every 4096 basepairs

Method:

DNA has 4 nucleotides (A, T, G, C) and the recognition site is 6 nucleotides long.

So 46 = 4096 bp long.

    To estimate the number of cleavage sites in a particular piece of DNA with a known size, you can apply the formula, N/4 n where N is the number of base pairs in the target DNA and n is the number of bases in the recognition sequence of the restriction enzyme.
