T5-The unpaired nucleotides produced by the action of restriction enzymes are referred to as
|
|
sticky end.
|
|
|
base sequence.
|
|
|
single strands.
|
|
|
restriction fragments.
|
Explanation:
Detailed explanation-1: -The unpaired nucleotide produced by the action of restriction enzymes are referred as sticky ends. Sticky ends are very useful in rDNA because they can be used to join two different fragments of DNA that were isolated by the same restriction enzyme. So, the correct answer is “sticky ends"
Detailed explanation-2: -A straight cut of restriction enzymes generates blunt ends, where both strands terminate in a base pair.
Detailed explanation-3: -Definition. noun, plural: sticky ends. (molecular biology) A fragment of DNA (often produced by a staggered cut on the DNA using restriction enzymes) in which the terminal portion has a stretch of unpaired nucleotides, and the strands are not of the same length.
