Answer:
The correct answer is C oxygen is directly used during aerobic respiration reactions .
Explanation:
Cellular respiration deals with the breakdown of sugar molecule basically glucose in presence of oxygen(in case of aerobic respiration) or in absence of oxygen (anaerobic respiration) to generate breakdown products such as ATP.
During aerobic respiration reactions oxygen is directly used.The oxygen reacts with glucose in 3 important step a glycolysis b TCA cycle and c oxidative phosphorylation to generate CO2,H2O and ATP molecules.
I think
Prometer---> Spot where transcription begins
Operator ---> On/Off switch
Terminator ---> Spot where transcription ends

The characteristic feature of the semi-conservative replication of DNA is formation of the leading strand and the lagging strand. DNA polymerases are the enzymes that can add nucleotides to the 3 ' end of the DNA strand only. A DNA double helix is anti-parallel in which one strand runs from 5 ' to 3 ' and the other from 3 ' to 5 ' direction. On the strand having a primer with a 3 ' end, the synthesis of DNA is continuous and forms the leading strand. On the other strand, DNA fragments called Okazaki fragments are produced with multiple RNA primers. It is called the lagging strand. The enzyme DNA ligase joins these Okazaki fragments on the lagging strand. Thus, any defect in the enzyme will affect the lagging strand only and not the leading strand as it does not have any Okazaki fragments.
