Companion PDF worksheet for Edexcel IGCSE Biology Lecture 42 - Nucleic Acids. Contains short answer questions, an activity requiring lateral thinking and exam-style questions. Specification Point 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). Specification Point 3.17B - Understand that an RNA molecule is single stranded and contains uracil (U) instead of thymine (T). Specification Point 3.18B - Describe the stages of protein synthesis including transcription and translation, including the role of mRNA, ribosomes, tRNA, codons and anticodons. Complete set of Chapter 5 Worksheets are available.

Companion PDF worksheet for Edexcel IGCSE Biology Lecture 47 - Mutations. Contains short answer questions, an activity requiring lateral thinking and exam-style questions. Specification Point 3.35B - Understand how a change in DNA can affect the phenotype by altering the sequence of amino acids in a protein. Specification Point 3.36B - Understand how most genetic mutations have no effect on the phenotype, some have a small effect and rarely do they have a significant effect. Specification Point 3.37B - Understand that the incidence of mutations can be increased by exposure to ionising radiation (for example, gamma rays, x-rays and ultraviolet rays) and some chemical mutagens (for example, chemicals in tobacco). Complete set of Chapter 5 Worksheets are available.

Companion PDF worksheet for Edexcel IGCSE Biology Lecture 45 - Cell Division. Contains short answer questions, an activity requiring lateral thinking and exam-style questions. Specification Point 3.28 - Understand how division of a diploid cell by mitosis produces two cells that contain identical sets of chromosomes. Specification Point 3.29 - Understand that mitosis occurs during growth, repair, cloning and asexual reproduction.
