Answer: synthesize a pre-rRNA 45S (35S in yeast), which matures and will form the major RNA sections of the ribosome. RNA polymerase II synthesizes precursors of mRNAs and most snRNA and microRNAs. RNA polymerase III synthesizes tRNAs, rRNA 5S and other small RNAs found in the nucleus and cytosol.

Answer:
The correct answer will be-gas absent in primordial atmosphere (oxygen).
Explanation:
The Miller experiment was performed in 1953 to show that organic molecules can be formed from the inorganic molecules in the conditions resembling the primordial atmosphere.
Same conditions were created to the unstable atmosphere like a mixture of gases which included- methane, sulfur dioxide and hydrogen but lacked oxygen as it was absent in the primordial atmosphere.
Thus, gas absent in the primordial atmosphere (oxygen) is the correct answer.
B. Systolic is when the heart beats. Diastolic is the heart at rest.
