Base Pairing – DNA and Transcription For the audio version of the file, click this link: Base Pairing Worksheet Audio The Central Dogma: DNA RNA Protein
It involves a thermal cycler and three repeating steps: • Denaturation - DNA is heated to separate strands • Annealing – Primers are introduced to designate copying points • Elongation - Taq polymerase* synthesises new strand 30 cycles will produce over 1 billion copies of desired DNA sequence
In this activity, you will build your own model to understand how DNA works. DNA is a simple molecule made up of four types of chemical building blocks called nucleotides: adenine (A), thymine (T), cytosine (C), and guanine (G). In the 1950s, James Watson and Francis Crick, using data generated by Rosalind Franklin and other scientists, built a ...
Knowledge of the structure and function of DNA and RNA is key to an understanding of molecular biology and cellular genetics. The processes of transcribing DNA to create mRNA and translating RNA to produce a sequence of amino acids are fundamental functions of cells.
Learning Objectives. By the end of this section, you will be able to do the following: Describe the structure of DNA. Explain the Sanger method of DNA sequencing. Discuss the similarities and differences between eukaryotic and prokaryotic DNA. The building blocks of DNA are nucleotides.
