The first cells on the planet almost certainly lived off of the nutrients that had built up in the oceans since they were incapable of producing their own food. DNA contains deoxiribose sugar and RNA contains ribose sugar. DNA is more stable as a double helix and RNA usually occurs as a single strand. DNA bases include A, T, C and G and RNA bases include A, U, C, and G. e. DNA is relatively immobile, confined to the nucleus, and RNA is mobile and moves from the nucleus to the cytoplasm. Eventually, cells arose that could harness light energy and use it to produce chemicals that store energy.
Translation is an energetically expensive process.
The end product of translation is proteins. A population is observed for about ten generations. In that time, the gene F is extensively studied and its allelic frequencies are not seen to change. During the industrial revolution, the number of dark peppered moths in Manchester, England, increased and the number of speckled moths decreased. RNA can carry more genetic information than DNA can.
