Chromosome strands strutting their stuff in an onion root. Unlike us, plants' growing areas are mainly restricted to specialised areas called meristems which are found in the tips of roots and shoots, and in cambial tissue between xylem and phloem.
Special staining techniques capture the cells' chromosomes and the various stages of mitosis can be seen.
See this article for more information.DNA, the stuff of chromosomes. Watson and Crick discovered its structure in 1953, basing their model on the X-ray diffraction pictures of Rosalind Franklin. They never properly acknowledged her vital contribution.
DNA garden at Charles Jencks' the Garden of cosmic speculation. I had heard about this garden several years ago. It is only open one day a year and this year I was able to visit it (along with thousands of others). The anticipation rather exceeded the reality .... I'm not sure what I expected. I suspect all the crowds made things less accessible.
One day a year???? Hmmmm. That's a "meandering" that probably needs some adjusting on someone else's end besides yours, Anne!
ReplyDeleteWould you believe that next year they are not opening because the gardens are being renovated? It was an odd experience, I had been really looking forward to going but have enjoyed it more in retrospect as I look through the pictures I took.
