Question

Fill in the blank:

The single base ends created when DNA is cut with an enzyme have a high likelihood of finding complementary ends when placed in solution and adhering through hydrogen bonding to form new DNA combinations. These ends are often referred to as __________ ends.

Answer 1

ANSWER IS:

The single base ends created when DNA is cut with an enzyme have a high likelihood of finding complementary ends when placed in solution and adhering through hydrogen bonding to form new DNA combinations. These ends are often referred to as sticky ends.

EXPLANATION:

Sticky ends are single-stranded ends of DNA fragments that are cut by restriction enzymes. These ends are complementary, so have a high likelihood of finding complementary ends when placed in solution and adhering through hydrogen bonding to form new DNA combinations.

These complementary sticky ends associate by hydrogen bonding. When DNA molecules after restriction enzymes cut, then exposed, and result is that complementary sticky ends associate by hydrogen bonding.
