WebDifferentiation from visibly undifferentiated precursor cells occurs during embryonic development, during metamorphosis of larval forms, and following the separation of parts in asexual reproduction. ... It was only at this point that the central process of biology—the synthesis, one after the other, of DNA, RNA, and protein—appeared. ... WebA second version of the central dogma is popular but incorrect. This is the simplistic DNA → RNA → protein pathway published by James Watson in the first edition of The Molecular Biology of the Gene (1965). Watson's version differs from Crick's because Watson describes a two-step (DNA → RNA and RNA → protein) process as the central dogma. While the …

WebTranscription factors are proteins that regulate the transcription of genes—that is, their copying into RNA, on the way to making a protein. The human body contains many … WebDifferentiation. When a cell differentiates (becomes more specialized), it may undertake major changes in its size, shape, metabolic activity, and overall function. Since all cells in the body, beginning with the fertilized egg, contain the same DNA, how do the different cell types come to be so different? The answer is analogous to a movie script.
WebTranscription and translation are the means to which cells read out, or utter, the genetic help in own names. Because many identical RNA copying ca live made from and same dna, and each RNA molecle can gleich the synthesis of many identical protein molecules, cells can synthesize a large amount of protein rapidly when requires. But each gene can also be …
