please answer all 3 questions by choosing the correct answer thank you!
What happens in the reaction when the temperature shifts to 55 Cduring cycling? Select one: a. the DNA polymerase will carry out DNA synthesis by extending the annealed primers b. the DNA polymerase will finish DNA synthesis X c. the primers anneal to the single-stranded regions of the DNA d. the primers anneal to the double-stranded regions of the DNA. During cycling, what occurs when the temperature is at 72 C? Select one: a. the primers anneal to the double-stranded regions ofthe DNA b. the DNA polymerase will carry out DNA synthesis by extending the annealed primers c the primers anneal to the single-stranded regions of the DNA X d. the DNA polymerase will finish DNA synthesis You designed a set of primers to amplify 1 kb DNA with polymerase chain reaction. By which cycle of polymerase chain reaction, we would expect to see the first amplified DNA with expected size? Select one: a. The end of cycle 1 b. he end of cycle 2 The end of cycle 4 X d. The end of cycle 10Explanation / Answer
