Section 7.2 of the Edexcel Biology A Level B course covering the following syllabus points
i Know that transcription factors are proteins that bind to DNA.
ii Understand the role of transcription factors in regulating gene expression.
iii Understand how post–transcription modification of mRNA in eukaryotic cells (RNA splicing) can result in different products from a single gene.
iv Understand that gene expression can be changed by epigenetic modification, including non-coding RNA, histone modification and DNA methylation.
v Know that epigenetic modification is important in ensuring cell differentiation.
A Level Biology Topic 7 - Modern Genetics
Edexcel Biology B
PowerPoint presentation of over 100 slides covering the whole topic
This topic builds on the knowledge of nucleic acids and proteins and how they are involved in gene expression. Knowledge of epigenetics, the use of stem cells and how these are contributing to medical advances are considered. The ethical
implications of the use of gene technology in scientific developments are discussed.
7.1 Using gene sequencing
7.2 Factors affecting gene expression
7.3 Stem cells
7.4 Gene technology
This is a fully editable PowerPoint presentation designed specifically for the new Edexcel A Level Biology B Specification for first teaching in 2015. It covers the whole of Topic 8. Each specification objective is covered in just the right amount of detail with clear diagrams and clever slide animations.
This presentation is over 80 slides long!
Although it is designed for the Edexcel specification much of its content is relevant for other A Level courses.
