Restriction endonucleases cut DNA at specific sites, known as recognition sites, to produces DNA fragments useful for cloning. Restriction enzymes or restriction endonucleases are DNA cutting enzymes found in bacteria. Each restriction enzyme recognizes one or a few restriction sites. When it finds its target sequence, it makes a double stranded cut in the DNA molecule.
Answer:
Essential to the formation of all known life, evidence of stable liquid water elsewhere could indicate an environment beyond Earth that could sustain the formation of extraterrestrial life
Explanation:
If there is water on other plants, Mars for example, then that shows there may be a sign of living life or a opportunity for us.
Answer:
Prokaryotic cells have a cell wall, Eukaryotic cells do not. Eukaryotic cells are much larger an are in fact more complex then Prokaryotic cells. Eukaryotic cells have a true nucleus bound by a doubled membrane. Prokaryotic cells have no nucleus.
Explanation:
DNA polymerase is the enzyme that is responsible for adding correct nucleotide pairs to new and growing DNA strands. Mismatched base pair errors will occur if this enzymes is not able to function optimally. There are other system that work DNA polymerase, these are proof reading system and mismatch repair system. Less than optimum function of these system will lead to uncorrected mismatched base pairs.
