Answer:

Answer: There are 9 ways to make a single base mismatch, 27 ways to make a two base pair mismatch and, again, 27 ways to make a three base pair mismatch (and only 1 way to do it correctly). Q = e − U i k b T i ∑ = e − U zeromismatches k b T + 9 × e − U onemismatche k b T + 27 × e − U twomismatches k b T + 27 × e − U threemismatches k b T = e 0 k b T + 9 × e − 10 kJ / mol k b T + 27 × e − 20 kJ / mol k b T 27 × e − 30 kJ / mol k b T = 1 + 9 × (0.018) + 27 × (0.00033) + 27 × (0.000006) = 1 + (0.163) + (0.0089) + (0.00016) =1.17 p 0 = e − U 0 k b T Q = e − 0 k b T 1.17 = 1 1.17 = 0.853 => 85.3% Therefore, approximately 85.3% of all amino acids are translated faithfully. The redundancy built into the genetic code and other energetic considerations raise this number considerably.

Which Lewis electron-dot diagram is correct for CO2?
Effectus [21]

Answer:

see explanation

Explanation:

The Lewis structure of a substance is otherwise known as its dot electron structure. It gives an immediate picture of the bonding and number of electron pairs in the molecule. The diagram shows only the valence electrons on each of the bonding atoms in the molecule and how they combine to form the molecule under consideration.

The correct Lewis structure for CO2  is shown in the image attached. CO2 has 16 valence electrons. This can be verified by counting the number of dots in the image attached.
