1.Three<span> major </span>types of RNA<span> are mRNA, or messenger </span>RNA<span>, that serve as temporary copies of the information found in DNA; rRNA, or ribosomal </span>RNA<span>, that serve as </span>structural<span> components of protein-making </span>structures<span> known as ribosomes; and finally, tRNA, or transfer </span>RNA<span>, that ferry amino acids to the ribosome to be assembled 2.</span>Transcription<span> is the </span>process<span> by which DNA is copied (</span>transcribed<span>) to mRNA, which carries the information needed for protein synthesis. </span>Transcription<span> takes place in two broad steps. First, pre-messenger RNA is formed, with the involvement of RNA polymerase enzymes. 3.</span><span>n molecular biology and genetics, </span>translation<span> is the </span>process<span> in which ribosomes in a cell's cytoplasm create proteins, following transcription of DNA to RNA in the cell's nucleus. ... In </span>translation<span>, messenger RNA (mRNA) is decoded by a ribosome, outside the nucleus, to produce a specific amino acid chain, or polypeptide. 4.</span>DNA is the genetic holder in our body ! for any message DNA has to convert in RNA and then protein resulting in all the traits we have ! so on transcription DNA information is converted to RNA and during translation into protein .... thus these protein helps in building our appearance , our Personalities every thing !
