Does exercise change your DNA? - Genomics Aotearoa
Peter Dearden • Feb 03, 2015 •
Peter K. Dearden Last week, on Facebook, an interesting article from the New York Times was being shared. The headline read “How Exercise Changes Our DNA”, and, despite the provocative title, the article underneath was pretty good. The article explains how a recent published experiment showed that exercise changes some aspects of our DNA. To uncover what … Read More
Is a genome enough? (Not Just DNA #1) - Code for life
Grant Jacobs • Oct 02, 2013 •
Answering a question from the Tuatara genome blog and starting a new series, Not Just DNA.[1] We are entering the age of the genome.[2] Our genomes tell us about ourselves. Genome sequences show our evolutionary relationships with other species. They reveal the origin and migration of humans. Unwelcome changes to our genomes can … Read More
Terry Speed on Epigenetics - Code for life
Grant Jacobs • Jun 21, 2013 •
Epigenetics is an increasingly used jazz word, and I don’t just mean by scientists. You can see it in magazine articles, marketing spiels, and so on.* It’s touted as some kind of new, special genetics. Epigenetics itself isn’t new. It’s basically the business of how our cells express their genetics, how the characteristics of … Read More
Epigenetic dynamics – free - Code for life
Grant Jacobs • Mar 15, 2013 •
Those with interests in epigenetics and genome structure may want to check out Nature Structural and Molecular Biology’s focus on epigenetic dynamics. (This gives me an opportunity to briefly sound off on a favourite topic…) One fascinating development over the past few years has been explorations of the three-dimensional nature of genomes, how they are … Read More
Epigenetics – introductory explanations - Code for life
Grant Jacobs • Feb 06, 2013 •
Epigenetics is a term that is increasingly being heard of outside of molecular biology or genetics. One of my interests is how gene regulation works, how the molecules that control genes do their thing. You can think of epigenetics as gene regulation through controlling the availability of genes to be used or not. While … Read More
Structured procrastination, 2 Dec 2012 - Code for life
Grant Jacobs • Dec 03, 2012 •
Another edition of my irregular structured procrastination reading lists - have fun exploring these. (Geekier ones nearer the end.) Sci-fi movie Geneticist Ricki Lewis offers a review of Jim, which she says is more compelling than GATTACA. The movie can be viewed on-line. (If you watch it, let me know what you think.) … Read More
Structured procrastination, 23-Aug-2012 edition - Code for life
Grant Jacobs • Aug 23, 2012 •
Long-time readers will know ‘Structured procrastinations’ are when I point to interesting or quirky articles, usually on the less academic side, to clear tabs out of my web browser. What was that about impact factors, Nature? Criticising their inflated status under a banner headlining your own impact factor… … Read More
Epigenetics overview (video) - Code for life
Grant Jacobs • Apr 11, 2012 •
Below Jessica Tyler, from the University of Texas MD Anderson Cancer Center, introduces epigenetics, a topic I’ve touched on a few times and would like to elaborate further on. Her introduction is fairly gentle; hopefully some of the essence of the thing will come across to non-specialists! [vimeo width=”600″ height=”450″]http://vimeo.com/39781892[/vimeo] You may need to wait until … Read More
Transcribing a gene, free poster - Code for life
Grant Jacobs • Jan 30, 2011 •
If you’re looking for a pictorial overview of gene transcription–the process of making a RNA copy of a gene–or just like making up posters to put on your walls, you might like to download this free poster (1.94 Mb PDF) from Nature Reviews Genetics by Vikki Weake and Jerry Workman. As you … Read More
