And for some time people said, "Maybe this could be a It was this kind of this molecule that was inside of nuclei of cells. Storing the information." Just to be clear, DNA "Hey, that looks like "the molecule that's But it's really the structure of DNA that made people say, The bulk of the data for Watson and Crick's work, Maurice Wilkins and many, On the work of many others especially folks like Rosalind Franklin who essentially provided Not until the structure of DNA was established by Watson and Crick and their work was based Question wasn't figured out until fairly recent times, until the mid 20th century. Even he didn't know exactly what was the molecularīasis for inheritance. How inheritance happened, then you even could start to breed certain types of things. Understand the mechanisms or he was trying to understand But even then, even Mendel who was starting to
Way with Gregor Mendel the father of genetics. But it wasn't until theġ800 that that started to be studied in a more scientific For example, someone might have told you, "Hey, you walk kind of like your dad," or, "Your smile is kind of like your mom," or, "Your eyes are like one of your uncles "or your grandparents." And so there's always been this notion of inherited traits. They have noticed that offspring tend to have traits in common with the parent. Human beings have been around I could imagine that If it were added to natural DNA the structure would alter and the DNA would create different amino acid sequences leading to different proteins made and different life forms essentially. An artificial nucleobase sounds cool! I would love to see what types of structures and processes it could do. Uracil is unique and can bond to other uracils in RNA giving it the ability to differentiate its structure for survival purposes. Methylation is a defense mechanism from an enzyme found in some bacteria and viruses (nucleases) and all DNA are methylated.
In transcription RNA is used which used Uracil instead of Thymine during the synthesis of DNA the uracil is methylated by folic acid which converts it to thymine. The bases (A-T) bond through hydrogen bonding. For the two strands of the double helix to fit neatly, a pyrimidine must always be paired with a purine.To have a structural piece of DNA or RNA the nucleotides consist of a nucleic acid (differing Uracil in RNA from Thymine in DNA) a deoxygenized sugar (DNA) or oxygenized sugar (RNA) and a monophosphate (PO4) The bases are the 3 structures (nucleic acid, ribose and phosphate) bond together with a strong bond called a phosphodiester bond. If these pairings were ever to occur, the structure of DNA would be like a staircase made with stairs of different widths.
