Help your students build real understanding of regulation of gene expression through ninety questions that move from basic recognition to genuine reasoning about living systems.
Among the ninety questions, students will see prompts such as "How do post-translational modifications affect transcription factors?", "What effect do chromatin remodeling complexes have on gene expression?", and "Which of the following is a mechanism by which transcription factors can activate gene expression?"
Because the three worksheets share the same content in three different formats, you can spread them across the week: one for diagnosis, one for practice, and one for assessment, without repeating a single question.
This set is part of a complete NGSS aligned biology unit. The unit also covers Introduction to Cell Division, Embryonic Development in Animals, Role of Stem Cells, Hormonal Control of Development, Environmental Influences on Growth, and Programmed Cell Death (Apoptosis), all in the same three worksheet format, so your classroom routine stays familiar while the topic changes.
Suitable for Grade 9-12 biology classes, and for NGSS aligned review at any point in the school year. This set is aligned to NGSS standard HS-LS1-4.
