PowerPoint for topic 7.2 Factors affecting gene expression of A Level Biology Edexcel B 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.

This is a full animated and editable teaching PowerPoint for Edexcel Biology B A Level Section 5. It covers respiration and photosynthesis. However, it will be relevant to all A level Biology courses. It covers the following: ATP Aerobic Respiration Summary Glycolysis Link Reaction Krebs Cycle Oxidative Phosphorylation Electron Transport Chain Chemiosmosis Anaerobic Respiration Photosynthetic pigments Light-dependent reactions Cyclic and non-cyclic photophosphorylation Calvin Cycle The PowerPoint is 90 slides long!

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 3 which is Classification and Biodiversity. Each specification objective is covered in just the right amount of detail with clear diagrams and clever slide animations. This presentation is almost 100 slides long! Although it is designed for the Edexcel specification much of its content is relevant for other A Level courses.

New Edexcel IGCSE 9-1 4BI1 syllabus for 2017 first examined in 2019 This is a PowerPoint presentation for the topic - Section 3b Inheritance - DNA and Genes 3.14 understand that the genome is the entire DNA of an organism and that a gene is a section of a molecule of DNA that codes for a specific protein 3.15 understand that the nucleus of a cell contains chromosomes on which genes are located 3.16B describe a DNA molecule as two strands coiled to form a double helix, the strands being linked by a series of paired bases: adenine (A) with thymine (T), and cytosine © with guanine (G) 3.17B understand that an RNA molecule is single stranded and contains uracil (U) instead of thymine (T) 3.18B describe the stages of protein synthesis including transcription andtranslation, including the role of mRNA, ribosomes, tRNA, codons and anticodons The file is fully editable, has plenty of original diagrams and animations along with true false concept check questions at the end of the presentation and an exam style question.

New Edexcel IGCSE 9-1 4BI1 syllabus for 2017 first examined in 2019 This is a PowerPoint presentation for the topic - Section 3b Inheritance - Cell Division 3.28 understand how division of a diploid cell by mitosis produces two cells that contain identical sets of chromosomes 3.29 understand that mitosis occurs during growth, repair, cloning and asexual reproduction 3.30 understand how division of a cell by meiosis produces four cells, each with half the number of chromosomes, and that this results in the formation of genetically different haploid gametes 3.31 understand how random fertilisation produces genetic variation of offspring 3.32 know that in human cells the diploid number of chromosomes is 46 and the haploid number is 23 The file is fully editable, has plenty of original diagrams and animations along with true false concept check questions at the end of the presentation and an exam style question.

This is a quick test to check the main factual knowledge for this topic. This is from a range of tests that cover the whole syllabus. This test is just for the double award biology. There is another set of tests for separate biology IGCSE The tests are based on the order of the CGP revision guide so it makes them easy to revise for. The answers are included
