List the 3 basic steps of DNA replication: a. b. c. One of the strands comes from the original strand. When creating new cells, each cell needs DNA. DNA are the instructions for the cell - without DNA the cell would not function. DNA double helix, Chromosome, Nucleus Helicase opens up the helix. Polymerase adds complimentary bases to the ...

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
There are base pairing rules for writing complimentary DNA strands for a given strand. In DNA, Adenine pairs with Thymine. Cytosine pairs with Guanine. In RNA, Adenine pairs with Uracil, instead of Thymine. DNA → mRNA → amino acid carried by tRNA. Note: the codon chart refers to the mRNA sequence.
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.
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 ...
DNA copies itself through the process of replication: The two strands of the double helix unzip, forming replication forks. New bases are added, following the rules of base pairing (A with T and G with C). Each new DNA molecule has one original strand and one new strand.
