Sep 8, 2023 · Biology definition: Translation is the process of translating (converting) the transcript (genetic information) from the mRNA into a specific sequence of amino acids in the growing chain of a polypeptide. The three general steps of translation are initiation, translation elongation, and translation termination.
The process of translation in biology is the decoding an mRNA message into a polypeptide product. Put another way, a message written in the chemical language of nucleotides is "translated" into the chemical language of amino acids.
Step 1: transcription! Here, the DNA sequence of a gene is "rewritten" in the form of RNA. In eukaryotes like you and me, the RNA is processed (and often has a few bits snipped out of it) to make the final product, called a messenger RNA or mRNA. Step 2: translation!
- N-terminal initiating methionine, although being the first amino acid, is not present at N-terminus of all proteins. This is because of a process t...
- The amino acids are actually brought by the tRNA from the cytoplasm to the ribosome. These types of RNA "transfer" the amino acids to all these sites.
- Excellent question! Translation is quite bit more complicated that this introductory material can cover. The sequence of the mRNA around a potentia...
- This is because when a gene is transcribed by RNA polymerase into pre-mRNA, it contains both coding (exon) segments and non-coding (intron) segment...
- The tRNA is a modified version of the mRNA , which is in turn made with the help of DNA
- An open reading frame (ORF) is a series of codons that begins with a start codon (usually AUG) and ends with a stop codon. There can be no addition...
- Yes it can, although it has a very short lifespan (a few hours).
- As for the start codon, I wonder if other permutations will work (like AGU or GAU for example), but I suppose there three stop codons for redundanc...
- the spliceosome
- Well, there is one enzyme which is crucial for translation and that is "aminoacyl tRNA synthetase". This enzyme attaches an amino acid to the tRNA....
Dec 30, 2022 · As we will see in the cell cycle chapter, proteasomes are a crucial component to precise regulation of protein functions. 10.8: Regulation of Translation not declared. Gene expression is primarily regulated at the pre-transcriptional level, but there are a number of mechanisms for regulation of translation as well.
Jul 30, 2022 · The process of translation, or protein synthesis, involves the decoding of an mRNA message into a polypeptide product. Amino acids are covalently strung together by interlinking peptide bonds. Each individual amino acid has an amino group (NH 2 ) and a carboxyl (COOH) group.
