Question 1 Which of the following factors contribute to the fact that the polarizability of helium is less than that of argon? Select all that apply. Helium's electrons are more tightly bound than those of argon, since they are closer to the nucleus. Helium's nucleus is smaller and the protons cannot move as far as those of argon. Argon has many more electrons that can adjust to an external electric field than does helium. Helium and argon are both inert gases and so do not...

1 out of 8 attempts The two strands of the DNA molecule are held together by hydrogen bonds between base pairs. When an enzyme unzips the molecule to separate the two strands, it has to break these hydrogen bonds. A simplified model represents a hydrogen bond as the electrostatic interaction of four point charges arranged along a straight line. The figure shows the arrangement of charges for one of the hydrogen bonds between adenine and thymine. Estimate the energy that...

2. The sequence below represents two DNA strands linked together by hydrogen bonds. The smaller DNA strand has a 3'-OH that will be used by the DNA polymerase to add nucleotides using the longer DNA strand as a template. You add dATP, SCTP, dTTP, and ddGTP (dideoxy-GTP); and incubate at the DNA polymerase optimum temperature to allow the extension of the smaller DNA strand. Using the symbols below, draw the extended DNA strand (you don't need to draw the template...
