A为自然数,A+AA+AAA=1011,求A=?(答案:二进制)。注:10进制下,此加法竖式无解。提示:需先确定合适的进制,换言之,在何进制下有解!①记进制为a,则a>1且a>A。由三数之和的个位为1可知,3A=1(舍弃)或a+1或2a+1;由三数之和的十位为1可得,2A+1=a+1或2a+1、或2A+2=a+1或2a+1...
假设A 是一个一位数,那么 AA 就是 10A + A = 11A,AAA 就是 100A + 10A + A = 111A。 建立方程: 将这些表达式代入方程:A + AA + AAA = 1011。 得到:A + 11A + 111A = 1011。 解方程: 简化方程为:123A = 1011。 计算A 的值:1011 ÷ 123 = 8.22。 由于A 是整数,因此我们只能取整数解...
Mice were administered with a single injection of 1011 vg of AAV6.2FF-Luciferase (AAV-Luc) or AAV8-Luc. Beginning 1-week post injection, IVIS or DLIT images were acquired. D-luciferin, Sodium Salt (BioVision) was sterilely prepared 24 h before injection at a concentration of 15 mg...
Lafayette, CO, USA. It was used as a template to amplify the gene by PCR using a forward (5′-CGCGGATCCATGTTCCCACTGACTGAGGAAAACAAGC-3′) and a reverse (5′-CGCCTCGAGTTACTAGTCATCCAGAGCAGGTGG-3′) primer. The HuP10 gene was cloned between theBamHI andXhoI sites of pET28a (Novage...
. Although notable progress has been made on novel cancer treatments, the overall survival rate and therapeutic effects are still unsatisfactory for cancer
Genomic DNA was extracted from the young leaf of an individual Acacia hybrid (AaHy113F1) using the CTAB method (Doyle and Doyle 1990). DNA sequences obtained from our RACE PCR were used to design primers (Table 1) using Primer Premier 5 and Primer 3 software for the amplification of the...
#图文万粉激励计划#这是一道“另类”加法竖式:进制未知且未定!难哭孩子,难倒家长!如图,A+AA+AAA=1104,求A=?提示:先确定进制a即“满a进1”!①a≥5,A<a。②个位数字3A=a+4或2a+4。③若3A=a+4则十位数和2A+1=a或2A+1=2a(矛盾,舍弃!),从而百位和A+1≤a,无法等于a进制下的11。故此...

pWSC17 (pggr-2::GFP): pWSC05 was cut with SalI and SphI and ligated to a PCR product of pgrr-2 from N2 genomic DNA (forward primer, oWSC40: AATGAAATAAGCTTGCATGCTCTTCCGGCAGATGCGCTGTT, reverse primer, oWSC41: ATCCTCTAGAGTCGACGCCGTCGTGGTAAGACGTTATAGTT), cut with SphI and SalI....
(Fig.1A). The coding sequence contains 918 bp that encodes a protein of 305 aa with an estimated molecular mass of 35,638.68 daltons and a theoretical pI of 9.03. Bioinformatic analysis also indicated that this protein lacks a signal peptide; however, the MitoPro II program predicted the ...
