Dna fragments form during dna replication due to the discontinuous nature of replication on the lagging strand. dna fragments can form from being cut by restriction endonucleases. the process (i, ii, and iii) above shows the joining of two dna fragments by an enzyme. what enzyme is modeled using the yellow oval above?
a) helicase
b) dna ligase
c) rna polymerase
d) dna polymerase

Phosgene (carbonyl chloride), cocl2, is an extremely toxic gas that is used in manufacturing certain dyes and plastics. phosgene can be produced by reacting carbon monoxide and chlorine gas at high temperatures: co(g) cl2(g)⇌cocl2(g) carbon monoxide and chlorine gas are allowed to react in a sealed vessel at 477 ∘c . at equilibrium, the concentrations were measured and the following results obtained: gas partial pressure (atm) co 0.830 cl2 1.30 cocl2 0.220 what is the equilibrium constant, kp, of this reaction
