A Positive control by definition requires some type of activation in order to proceed. B RNA polymerase is required for transcription, not replication. Other enzymes listed are all involved in replication. D Example discussed in class and on reading quiz. F Mutagens and UV lead to induced mutations.
Spontaneous mutations arise without external causes.
T Anaerobic respiration and dissimilatory reduction are synoymous. F 300 amino acids requires at least 900 base pairs of DNA, not 100. 20. F Anoxygenic phototrophs use cyclic photophosphorylation. So this is a lagging strand. The statement defines auxotrophs, not prototrophs.
