Metal response elements are the sequence of nucleotides in Gene promoter region which interact with the metal part of certain proteins. I want to know the sequences of such nucleotides in diffrent genes in human genome.
I have a research project on the element cobalt. I have read its a transition metal and when i look this up it, its defined as “an element whose atom has an incomplete d sub-shell”. What does this mean? Please explain what an incomplete d sub-shell means or if you can, try to explain what a transition metal is.
We know stone, bronze, iron and a steel alloy were all, at one point in history, used to make weapons such as swords and spears. However, we know now of many more metals and elements that we did not know of 2000 years ago.
With that said, other then bronze iron or steel, what metal or element would make a good, sturdy sword or shield?
