Phospholipids is the answer
I had to look for the options and here is my answer: When transcription of a protein-coding gene occurs in a bacterial RNA polymerase, what happens is that, it produces pre-mRNA. Pre-mRNA is also an RNA strand that is not yet matured and it is still to be synthesized.
Based on the observance of DNA, now appearing as 3 segments, the purpose of the enzyme was most likely to split and or break down, cut the DNA at appropriate sites of the respective nucleotide sequences, that the enzyme can recognize and cut, ultimately producing these 3 segments.
P + q = 1
p = 1 - q
p = 1 - 0.37
p = 0.63
therefore, the frequency of P is C) 0.63.
