Bacillus thuringiensis subsp. israelensis produces a potent mosquitocidal protein, Cry4A. We have identified a 15-bp catabolite responsive element (cre), overlapping the -35 element of the cry4A promoter. Changing a guanine to adenine at position -49 in the promoter abolished glucose catabolite repression of cry4A and enhanced promoter activity two- to threefold. This cis regulatory element is ...

Generalisation is a key feature of learning algebra, requiring all four proficiency strands the Australian Curriculum: Mathematics (AC:M): Understanding, Fluency, Problem Solving and Reasoning. From review literature, we propose progression for algebraic generalisation consisting five levels. Our then elaborated validated by reference to large range assessment tasks acquired from previous proje...
