b)Each fragment has short, single-stranded"sticky ends".
c) They contain identical nucleotides running int the same direction.
d) The fragments unzip completely, forming single-stranded DNA


2. The first experiment that was successfully demonstrated genetic engineering was conducted by Cohen and Boyer. In the experiment a plasmid from E. Coli served as a ______________.

Answer 1

Answer 2

?

Answer 3

1.Many restriction enzymes cut in an offset fashion. The ends of the cut have an overhanging piece of single-stranded DNA. These are called "sticky ends" because they are able to form base pairs with any DNA molecule that contains the complementary sticky end

Answer 4

so the answer is
a ?

Answer 5

1 is not a . Try again :)

Answer 6

since they develop sticky ends im guessing b

Answer 7

Yes. Your correct :)

Answer 8

thanks
now the second one

Answer 9

is it a vector

Answer 10

Yes. you are brilliant :)

Answer 11
