Possibly influenced by Danish grim (âsoot, grimeâ), Old Dutch grijmsel, Middle Dutch grime, Middle Low German greme (âdirtâ). Dirt, grease, soot, etc. that is ingrained and difficult to remove.
messenger RNA. a molecule of RNA that is synthesized in the nucleus from a DNA template and then enters the cytoplasm, where its genetic code specifies the amino acid sequence for protein synthesis.
messenger RNA (mRNA) is a copy of genomic DNA that codes for a specific protein. DNA cannot leave the nucleus and enter the cytoplasm, where ribosomes make the proteins. There â¦ fore there need to be a way to get the code that's on the DNA to the ribosomes so that it can become protein. mRNA is the solution.ll cellular organisms use messenger RNA (mRNA) to carry the genetic information that directs the synthesis of proteins. In addition, some viruses use RNA instead of DNA as their genetic material; perhaps a reflection of the suggested key role of RNA in the evolutionary history of life on Earth.
