The right answer is The digestion of DNA by restriction enzymes.
The fragmentation of the DNA is done by bacterial enzymes called restriction enzymes.
Restriction-enzymes (or endonucleases) recognize and cut the DNA into a specific sequence. These enzymes are naturally produced in bacteria as a defense against bacteriophages - viruses that infect bacteria. The bacterial restriction enzymes cut the DNA of the invasive bacteriophage while leaving the bacterial genomic DNA healthy and safe through the addition of methyl groups.
These enzymes are used in practice at the laboratory level to explore DNA.
Answer:The rocks are smooth due to the water eroding the rocks.
Explanation:
The water slowly takes off minerals of the rocks every time is splashes over them. Over time the rocks bumpy surface would be eroded away giving it a smoother surface.
True. In order fora child to have dimples, one parent must have them visible.
Answer:
A) parietal cells
Explanation:
Parietal cells are the epithelial cells of the stomach that have the function to secrete hydrochloric acid (HCl) and intrinsic factor. Parietal cells contain canaliculi – secretory network for the secretion of HCl via active transport.
Parietal cells are regulated via several factors such as acetylcholine, gastrin and histamine. So, if histamine receptors are blocked via antacid drugs , the secretion of the acid will be reduced.
Reproduction. Mitosis is a reproductive process in which the cell splits in two and multiplies.
