| 3 | 大肠杆菌DNA聚合酶Ⅰ的“碱基选择”作用显示文摘用双脱氧核苷酸研究了大肠杆菌DNA聚合酶Ⅰ的Klenow片段的“碱基选择”作用.当引物末端为3’OH时,Mn2+代替Mg2+对dNTP的Km影响不大,而使ddNTP的Ki大大降低,非配对的ddNTP仍无抑制作用。当引物末端为ddNMP且与模板配对时是DNA合成的抑制剂,与模板配对的下一个dNTP可增强这一抑制作用,Mn2+代替Mg2+使dNTP的诱导作用大大增强而ddNTP无诱导作用。这些结果表明引物末端对于酶选择核苷酸起着重要作用,DNA聚合酶Ⅰ选择核苷酸的过程应是个有序的构象变化的过程。下一互补核苷酸的结合抑制3'→5'外切活性对引物末端ddNMP的水解作用为此提供了又一证据。 | 陆长德 El.,WS | 1995 | 生物化学与生物物理学报1995，27，6： | 1 |

| 5 | Effect of grass density and date of tapping on Acacia senegal gum yield in north kordofan state, Sudan显示文摘We conducted a two-factor experiment in randomized com- plete block design with four replications during 2004 in El Demokeya Forest Reserve and El Himaira Natural Forest, North Kordofan State, Sudan. The objective was to develop an understanding of the ecological effects of under-story vegetation and tapping date on the productivity of gum arabic from Acacia senegal as over story cover. The first factor was grass cover which was tested in four levels (100% and 50% grass cover in addition to bare and burnt). The second factor, date of tapping was tested in three levels namely (1st Oct, 15th Oct and 1st Nov). The first picking was done after 45 days from tapping and the gum yield up to seven pickings was collected at intervals of 15 days. Gum yield from each picking was collected and weighed using sensitive balance. Analysis of variance was carried out using MSTAT-C statistical package, and the Tukey test was applied for mean comparisons. The results showed highly significant differences (p<0.01) of grass cover on gum arabic yield in the two sites for most of the first consecutive pickings (1st-4th out of seven) in addition to total yield (kg/ha). With exception to the 4th pickings, the interaction effect between the grass densities and tapping date was not significantly different. The total gum yield was significantly (p<0.05) increased in only two pickings (third and fourth) in El Demokeya Forest Reserve and two pickings (1st and 2nd) at El Himaira Natural Forest. The density of grass cover significantly (p<0.05) affected the number of pickings at both sites; the number of gum pickings was directly proportional to grass density. The number of gum pickings was found to be significantly (p < 0.05) increased at the early date of tapping. | Idris M. Adam M. E. Ballal Kamal El. M.
