What Are the Biggest Benefits of Transcription?īeyond saving your fingers from trying to fly quickly to capture everything in a meeting, transcription has many advantages! If you check a thesaurus for synonyms of this version of transcribe, you’d find word lists that include terms like rewrite, write up, translate, render, transliterate, and interpret.įor the purposes of this article, we’ll use the first definition mentioned above. Converting genetic information from a DNA strand into messenger RNA instead (this is used in biochemistry).Creating a phonetic transcription of something.Rearranging a piece of music for a different instrument.Transcription, however, has a few different applications in the English dictionary. In Latin, the word transcribo means “to transfer in writing” and can also be referenced as Latin transcribere, scribere, and scripts. What is the definition of “transcribe”? When we dig into the general etymology, the definition of transcribe is to make a written copy. Read on to learn more about how transcription works and the benefits of using it. Transcription can help you leverage the spoken word or dictation, whether it’s for content repurposing, note-taking, or reviewing training materials. If you’re scrambling to take notes during a meeting, it’s no wonder! This is a common reason to consider automated transcription instead, in which your audio or video files become text documents. This clover-leaf structure supports the eventual connection between every codon, anti-codon and amino acid.Did you know that the average person speaks 100 to 300 words per minute? The average person types at 40 words per minute. ![]() One of these hairpin loops contains a sequence called the anticodon, which recognizes and decodes the mRNA molecule three nucleotides (one codon) at a time during translation. The tRNA molecule actually contains three hairpin loops that form the shape of a three-leafed clover. ![]() Another more general example is tRNA, a central player in protein synthesis, which is partially formed by hairpin loops. Once a polymerase meets this loop, it falls of and transcription ends. One example of a hairpin loop is the termination sequence for transcription in some prokaryotes. There are many instances of the hairpin loop phenomenon among nucleic acid strands. Hairpin loops can also form in DNA molecules, but are most commonly observed in mRNA. mRNA hairpins can be formed when two complementary sequences in a single mRNA molecule meet and bind together, after a folding or wrinkling of the molecule. In RNA, the secondary structure is the basic shape that the sequence of A, C, U, and G nucleotides form after they are linked in series, such a folding or curling of the nucleic acid strand. Hairpins are a common type of secondary structure in RNA molecules. The resulting structure looks like a loop or a U-shape. ![]() I suppose if you were spectacularly unlucky it might even promote prion formation (a contagious toxic protein structure).Ī hairpin loop is an unpaired loop of messenger RNA (mRNA) that is created when an mRNA strand folds and forms base pairs with another section of the same strand. While I've never see any evidence that any of this ever actually happens, it seems possible that in rare cases the change might make an mRNA encode a toxic protein that could kill a cell or worse yet trigger cancer formation. ![]() (Note that this is almost certainly something that happens all the time since all biological processes make errors.) If so, probably not much since each gene typically will make multiple transcripts and most mRNAs have a very short lifetime. I'm not completely sure I understand your second question - are you asking what would happen if the "wrong" base was incorporated into an mRNA? This is briefly covered in the next article - short answer: yes, but transcription termination is still being actively studied and is not completely understood.
