Thenew DNA consists of an old parent strand and a new daughter strand. This process is called: A. Hydrolytic cleavage B. Helical pairing C. Semiconservative replication D. Heredity 相关知识点: 试题来源: 解析 答案:Semiconservative replication 生物多样性是指在一定时间和一定地区所有生物(动物、...
Precisely, superoxide anion and hydrogen peroxide have been reported to act as mitogens, thereby promoting the rate of DNA replication and cell proliferation in a variety of cultured cells.9, 10 Nonetheless, in excess amounts, oxygen-derived radicals are very harmful to living organisms. Besides ...
The method, which is derived from DNA shuffling [Stemmer, Nature 370 (1994a) 389-391], does not rely on DNA ligase but instead relies on DNA polymerase to build increasingly longer DNA fragments during the assembly process. A 1.1-kb fragment containing the TEM-1 beta-lactamase-encoding gene...
A major challenge in evaluating the importance of low magnitude transcriptional changes is that the level of replication used in a typical microarray experiment is insufficient to detect small changes given the technical and biological variability in the system. Although several methods appear to be ...
aIn the classical cell cycle, the nuclear DNA contents vary only within the range of 2C and 4C, where C is the haploid DNA content per nucleus. When mitotic DNA replication in somatic cells is not followed by cell division (a process called endoreduplication), variation of cellular ploidy le...

Each original strand is a therefore a template from which a new strand is synthesized based on complementary base pairing by DNA polymerase. The new DNA consists of an old parent strand and a new daughter strand. This process is called: 相关知识点: 试题来源: 解析 Semiconservative replication...
