Question

The possible number of SalI restriction sites in a 9 kb double-stranded DNA,
with all four bases occurring in equal proportion (rounded off to the nearest
integer)
is ________.​

Answer 1

Answer:

First, work out the frequency of occurrence of the restriction site as 1-in-x bases, as explained in the example for the Intermediate level calculation. Then take the size of the DNA in kb (kilobases) and multiply by 1000 to get the size in bases. Divide this by x and round to the nearest whole number.

Answer 2

Answer:

The possible number of SalI restriction sites in a 9 kb double-stranded ... all four bases occurring in equal proportion (rounded off to the nearest...

The frequency of cutting in a random DNA sequence for a given restriction enzyme is once per every 4n, where n is the number of bases in the restriction enzymes ...✔
