WebIn the mid-1950s, the physicist George Gamow extended this line of thinking to deduce that the genetic code was likely composed of triplets of nucleotides. That is, he proposed that a group of 3 3 successive nucleotides in a gene might code for one amino acid in a polypeptide. Gamow's reasoning was that even a doublet code ( 2 2 nucleotides per ... WebA cell’s set of DNA is called its genome. Since all of the cells in an organism (with a few exceptions) contain the same DNA, you can also say that an organism has its own genome, and since the members of a species typically have similar genomes, you can also describe the genome of a species. WebFeb 8, 2024 · The answer is that our genetic material contains much more than the units we call genes. Just as important are the switches that turn a gene on and off. And how cells read and interpret genetic instructions is far more complex in people than in those water fleas. DNA has a twisted, ladder-like structure. motorroutes lake district
