This user's manual describes the input and output variables as well as the job control language necessary to utilize the IMP-H apogee motor firing program, IMPMOT. The IMPMOT program can be executed as either a stand-alone program or as a member of the flight dynamics system. This program is used to determine the time and attitude at which to fire the IMP-H apogee boost motor. The IMPMOT program is written in FORTRAN 4 for use on the IBM 360 series computer.
The phosphorylation of thymidine is described for a variety of conditions at 65 C to demonstrate that the reaction could readily take place in deserts at the present time. This might be used as an indication that urea-phosphate mixtures could have been important as phosphorylating agents on the primitive earth. Reaction products were identified by comparing their chromatographic and electrophoretic mobilities with those of authentic materials and by enzymatic degradation. The results show that good yields of nucleotides are obtained when nucleosides are heated with urea-phospate mixtures at 65 C. Reactions proceed more rapidly at moderate humidities than in a stream of dry nitrogen. Occasional wetting results in even faster and more extensive reactions. There was no reaction for a mixture of urea and trimetaphosphate.
