Ever wonder how all the new cells in your body get a copy of your DNA? Well, it’s not sent through an office memo. DNA replication is a very intricate and fascinating process you don’t want to miss. In this video, we’ll give a brief overview of DNA replication for eukaryote cells and introduce 4 key players: ligase, DNA polymerase, primase, and helicase. We’ll also talk about why DNA can either run 5’ to 3’ or 3’ to 5’ by exploring the structure of DNA.
Copy number variation and the secret of life - with Aoife McLysaght
Evolution is powered by variation: the differences in DNA sequences. One hugely important form of difference is copy number variation, where genes are duplicated or deleted from one generation to the next.
In this Ri event, Aoife McLysaght from Univeristy of Dublin explains how copy number variations gave us colour vision, a sense of smell and haemoglobin in our blood, before exploring the role they play in diseases such as cancer, autism and schizophrenia.
The event ‘Too Much of a Good Thing’ was presented at the Ri on Friday 28 March and forms part of the Ri’s all-women line up for Friday Evening Discourses in 2014 as part of a year-long celebration of women in science.
Got milk? Fact is, most people don’t — and shouldn’t — because for them, ice cream and milkshakes are basically toxic. So why can some people drink milk and survive? Turns out they’re mutants! SciShow explains.
Science Friction №27 - Create Your Own Clone
On Orphan Black, scientists are capable of creating human clones. It turns out that scientists in real life are doing this as well. Find out how to create your own clone in this episode of Science Friction.
When a man and a woman have sex, it’s very possible that they can create a baby! This is nothing new, but is it possible for a baby to have three biological parents? Laci takes a look at how this is possible, and why it could actually result in healthier babies!
