chromosomes are different (XY). evaluate the chance of producing a male or female. 4.6.1.3 DNA DNA is a polymer made up of two strands forming a double DNA is found in chromosomes. A gene is a small section of DNA. Each gene for a sequence of amino acids to form a particular protein. The genome is all the genetic material of an organism. The genome has been studied and will be important for medicine in the future. Describe the structure of chromosomes, DNA and genes. Explain that a gene is a small section of DNA that codes for a particular sequence of amino acids to make a specific protein. Describe what the genome is. Explain how knowledge of the human genome will help medicine in the future, eg identifying genes linked to cancers, understanding and treating inherited disorders. It will also help trace human migration patterns. Explain the ethical issues related to DNA sequencing. 1 Recap key ideas by asking students to reorder by size: cell, nucleus, DNA, chromosome, gene, nucleotide.
