False, Some plasmids may reanneal without taking in any more DNA. when plasmid and foreign DNA are combined after being cut with the same restriction enzyme
Enzymes that cleave DNA are known as restriction enzymes. Each enzyme distinguishes one or more target sequences and cleaves DNA at or close to those sequences.
Numerous restriction enzymes produce single-stranded DNA overhangs at the ends of their cuts, which are often staggered. But some result in blunt endings.
DNA ligase is an enzyme that joins DNA. A single, unbroken DNA molecule can be created by joining two sections of DNA that have matching ends using ligase.
DNA ligase and restriction enzymes are employed in DNA cloning to splice genes and other DNA fragments into plasmids.
An enzyme that cuts DNA and recognises particular DNA locations is known as a restriction enzyme. A number of restriction enzymes make staggered cuts at or near their recognition sites to create ends with a single-stranded overhang.

Explanation:
its an attraction between two atoms. for a hydrogen bond it is hydrogen and another atom like oxygen (in water), flourine or nitrogen.
The impact on the human health as we try to stay ahead of the evolutionary process is actually very bad. It is a fact that the humans are living much longer nowadays than ever before, with the main reasons for that being the well developed medicine and healthcare, much better standard of living, and having less riskier jobs. On the other hand, the human health, without being treated, is actually at an all time low. The immune system is much weaker than it has been, with the main reason being the isolation of the outside world and the higher level of hygiene. The allergies are becoming an ever growing problem because of this, as the immune system doesn't even recognize certain outside bodies are they an enemies or not. The constant radiation for numerous sources has caused development of numerous diseases. The old age has increased the percentage of diseases such as cancer, Alzheimer, Parkinson, or sclerosis. The less active life-style and food over saturated with fats and sugars has caused numerous health problems as well. All in all, the human health has become dependent on the pharmacy and its products, and without it it will suffer badly.
