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.
Hydrogen ions rush out of the thylakoid, powering the reaction that produces ATP
Explanation:
As the electrons from the reactive center of photosystems are passed down the protein chain, their energy is harnessed to pump in H+ ions from the stroma into the thylakoid lumen. This creates an H+ proton gradient that has potential energy to do work. ATP synthase utilized this gradient to generate ATPs by chemiosmosis. As the H+ ions move down the concentration gradient through the protein molecule, the ATP synthase is able to phosphorylate ADP and convert them into ATPs – the energy currency of cells.
This same principle not only in the chloroplasts but also in the mitochondria.
