What we already know – a tuatara transcriptome | Sequencing - the Tuatara Genome We are not starting from scratch in our mission to understand the genetics of tuatara. Scientists have been working on these creatures for more than a hundred years, and in that time plenty of researchers have used tuatara DNA to try to understand the world. For the most part, these studies have used DNA sequences as witnesses to evolutionary history, rather than data from which to understand the day-to-day biology of tuatara. Hilary Miller is one researcher who has taken a genetic approach to understanding how tuatara work. Up until last year, there were a few hundred tuatara DNA sequences known to science. The sequences you published make up what’s called “transcriptome” – what does that mean? A transcriptome is a set of expressed genes in a given cell type. Is there a particular reason you used an embryo for the first transcriptome sequence? Before your study, what did we know about tuatara genetics. What was the most exciting result to come from the transcriptome study?
PCR Virtual Lab / Learn Genetics Primers are short pieces of DNA that are made in a laboratory. Since they're custom built, primers can have any sequence of nucleotides you'd like. In a PCR experiment, two primers are designed to match to the segment of DNA you want to copy. Primers are also necessary because DNA polymerase can't attach at just any old place and start copying away. DNA Polymerase is a naturally occurring complex of proteins whose function is to copy a cell's DNA before it divides in two. The DNA polymerase in our bodies breaks down at temperatures well below 95 °C (203 °F), the temperature necessary to separate two complementary strands of DNA in a test tube. Nucleotides are the building blocks that DNA molecules are made of.

Genetics Genetics includes the study of heredity, or how traits are passed from parents to offspring. The topics of genetics vary and are constantly changing as we learn more about the genome and how we are influenced by our genes.

Uniquely Me Take a closer look at the people around you. Chances are you’ll recognise that, while you share many features in common with them, there are other features and behaviours they have that are quite different from yours. For example, we all have 2 eyes but they come in many different colours and shapes. Why are we the way we are? Apart from identical twins, each of us has a unique genetic make-up that provides the instructions for our growth and development. However, how you look and act (your phenotype) is actually a result of the interaction between your genetic make-up and your environment. Some of these interactions happen before we’re even born, during embryonic development. In this context, we explore 2 fundamental questions: Why are we the way we are? Meet our scientists We meet 4 scientists who are actively involved in research to learn more about the interactions between genetic and environmental factors: Peter Dearden is the director of Genetics Otago.
The Discovery of Photosynthesis Who Discovered Photosynthesis? Photosynthesis is a very important and complex process in nature and some of its phases are still not completely understood. Photosynthesis in plants and a few bacteria is responsible for feeding nearly all life on Earth. It does this by taking energy from the sun and converting it into a storable form, usually glucose, which plants use for their own life processes. Animals that consume plants also make use of this energy, as do those that consume those that consume plants, and so on to the top of the food chain. As important a job as making all of the world's food is, there's another vital function that photosynthesis performs: It generates the oxygen that oxygen-breathing animals need to survive. From PBS's "NOVA" program Many scientists contributed to the discovery and understanding of photosynthesis throughout the ages; in this page are outlined some of those crucial milestone experiments that contributed to this effort.

Does Sunscreen Protect my DNA? In this laboratory experiment students explore how effectively different sunscreens protect yeast cells from damage caused by ultraviolet (UV) radiation. DNA contains the instructions for proper cell function; changes to DNA can cause cancer; skin cancer can be caused by exposure to UV radiation, which comes from the sun; and the meaning of SPF ratings on sunscreens. Class Time: Two 45 minute class times Prep Time: 1-2 hours Does Sunscreen Protect my DNA? Student Version Does Sunscreen Protect my DNA? Teacher pages include material supply contacts and teaching strategies to help students interpret and explore their data. Students follow simple step-by-step instructions to explore DNA damage caused by UV radiation.
