Answer:
C. 3, 2, 1
Explanation:
During a single PCR cycle, the very first step is the heat separation of the double stranded DNA. Primer binds only single stranded DNA/RNA because it has complimentary bases which match single strand of DNA/RNA that is why it is necessary to unwind both the strands of DNA by providing temperature.
As soon as the DNA strands have separated by increasing the temperature to ~ 95 °C, in the next step the primer binds the portion of DNA which is complimentary to the bases of the primer. In order for primer to bind DNA, the temperature is lowered to ~ 72 °C and the process is called as annealing.
Once primer has bound to the DNA, the next step is polymerization i.e. nucleotides which are the monomer units of DNA are added one by one with the help of enzyme named as Taq polymerase. This is how the strand extends ahead of primer and exact copies of the given DNA are produced.
Note: PCR may be considered as in vitro DNA synthesis or replication.
Plant photosynthesis and energy creation are complex processes involving carbon dioxide, water and sunlight, facilitated by multiple enzymes to create the basic sugar called glucose. Much of the glucose plants produce is immediately metabolized into different forms of energy that plants use to grow and reproduce. The portions of glucose that are not immediately converted to energy are converted to complex sugar compounds, called starches. These are produced after the photosynthesis cycle. Plants then store starches for future energy needs or use them to build new tissues.
I’m not trying my best friend for me to get a copy from you but I’m trying not my email address I just got a text saying I need internet to get a hold on you I don’t know why I didn’t answer your dukes question I don’t emerged from the thirteen British colonies established along the East Coast. Disputes over taxation and political representation with Great Britain led to the American Revolutionary War (1775–1783), which established independence. In the late 18th century, the U.S. began vigorously expanding across North America, gradually acquiring new territories, oftentimes displacing
