WebUnit 1 DNA & The Genome. In this Unit, learners will develop knowledge through study of DNA and the genome. The Unit covers the key areas of structure and replication of DNA, gene expression, and the genome. This Unit explores the molecular basis of evolution and biodiversity, while the unity of life is emphasised in the study of gene expression. Webnot all of these genes are expressed. 1. Some of the control of gene expression occurs during transcription. a) i) In the passage above, explain what is meant when it says that ‘not all the genes in a cell are expressed’ and how does this cause cells to be different?

WebGel electrophoresis is a technique used to separate DNA fragments according to their size. DNA samples are loaded into wells (indentations) at one end of a gel, and an electric current is applied to pull them through the gel. DNA fragments are negatively charged, so they move towards the positive electrode. Because all DNA fragments have the ...
