Transcription and translation
RNA is a lengthy chain of bases exactly like a strand of DNA, except that the beds base uracil (U) replaces the beds base thymine (T). Therefore, RNA contains triplet-coded information simply like DNA.
When transcription is set up, area of the DNA double helix splits open and unwinds. Among the unwound strands of DNA will act as a template against which a complementary strand of rna kinds. The complementary strand of RNA is called messenger RNA (mRNA). The mRNA separates from the DNA, actually actually leaves the nucleus, and travels in to the cellular cytoplasm (the an element of the mobile outside of the figure that is nucleus—see in a very Cell). Here, the mRNA attaches to a ribosome, that is a structure that is tiny the mobile where protein synthesis does occur. 继续阅读Transcription may be the procedure by which information coded in DNA is transferred (transcribed) to ribonucleic acid (RNA)
