Answer:
DNA restriction enzymes cut the DNA molecule, while DNA ligases join the resulting DNA fragments
Explanation:
Transformation is a naturally occurring process by which bacteria incorporate exogenous genetic material from their surrounding environment. This process (transformation) is used for DNA cloning via plasmid vectors. In DNA cloning, transformation occurs after restriction enzymes cut the DNA at specific sequences named palindromic sequences (i.e, sequences that can be read the same in opposite direction). Restriction enzymes can generate sticky-ends, where enzymes make staggered cuts in the two strands (e.g., <em>BamH</em>), or blunt ends, where the resulting strands are of the same length (e.g., <em>HaeIII</em>). In general, sticky-end enzymes are more useful because they generate a 3' overhang in one molecule and a complementary 5' overhang in the other, increasing the yield and specificity of ligation. During ligation, a DNA ligase is used to join both DNA strands by forming phosphodiester bonds in the plasmid. Following transformation, bacteria can be selected on antibiotic plates.
Answer:
If fracking can contaminate city water, it might also poison nearby rivers
Explanation:
It is a pretty challenging question, but in my opinion this is the correct answer. I have mor information for you,m fire does not extiguish with water because water has Oxygen and oxygen is what keeps fire alive, if you want to extinguish it you have to trap fire with CO2 or carbondioxide wich is the chemical that kills fire. I dont know if this answert is enough for you but I hope its the correct one.
The range of the set is 6.8,
because 8.7-1.9=6.8
