A-Level的题目显然与GCSE阶段的题目不一样，在A-Level阶段一分并不代表只有一个信息点，评分者会根据考生作答的理解情况和完整程度给予评分。The mark scheme often talks about “the idea that…”, meaning that we don’t necessarily have to state the exact mechanism behind something to achieve marks. ...
Second, we measured the level of proteins in a lysate and calculated the enrichment rank proportional to the difference in the abundance between lysates and a target pulldown. With all the metrics combined, 19 of 20 proteins among the top-most ranking 2% were known RNAP interactors (Fig. 1d...
exovorus epibiotic proliferation, even at the single-cell level. Altogether, these data highlight that B. exovorus cell division is not strictly binary and thereby more complex than initially considered10,11. The number of B. exovorus progenies is not determined by prey cell size The closely...
The structure similarity of TRY2 protease to insect enzymes might allow the fungal cells to evade host "non-self" recognition and thus might represents one important virulence determinant. The antisera against PR1 and PLB2 were raised, respectively. B. bassiana was grown in poor medium containing...

Abstract ㊀To investigate the effect of SOCS1a on liver oxidative stress in zebrafish,the liver tissues of zebrafish were analyzed by transmission electron microscopy (TEM),the activity of antioxidant enzymes and transcriptome between the SOCS1a -deficient adult ze-brafish and their control siblings...
These enzymes and functions are common to potato and tomato, suggesting that they are involved in the biosynthetic steps common to solanidanes and spirosolanes (Fig. 1). In addition, several uridine diphosphate-dependent glycosyltransferases (UGTs) involved in the glycosylation steps of SGA ...
rapidly attaining the high-level production of squalene and mogrol in the yeastSaccharomyces cerevisiae. Thus, this work demonstrates a facile synthetic biology strategy for the assembly and controlled expression of multigene metabolic pathways in industrial chassis organisms....
