Genetics. In biology, translation is the process in living cells in which proteins are produced using RNA molecules as templates. The generated protein is a sequence of amino acids. This sequence is determined by the sequence of nucleotides in the RNA. The nucleotides are considered three at a time.

Basically, a gene is used to build a protein in a two-step process: 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.
- You state that AUG is the start codon and also the codon for Methionine. Do all proteins made in cel...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...
- where are the amino acids attached to the transfer RNA coming from? in the pictures it makes it seem...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.
- Hi there I am curious - what stops a ribosome from attaching to another location that may be misread...Excellent question! Translation is quite bit more complicated that this introductory material can cover. The sequence of the mRNA around a potentia...
- Why is an actual gene that codes for a protein likely to be longer?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...
- Is the tRNA made from DNA, or its a preexisting molecule?The tRNA is a modified version of the mRNA , which is in turn made with the help of DNA
- what is the open reading frame? how does that fit into all of this?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...
- What happens to the mRNA after being translated? Can it be translated again?Yes it can, although it has a very short lifespan (a few hours).
- Re: the genetic code image Why are there 3 codons for stopping? Why is one not enough? Also then why...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...

- Are there any important enzymes involved in translation? In the article it says "the ribosome also a...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....
In biology, translation is the process in living cells in which proteins are produced using RNA molecules as templates. The generated protein is a sequence of amino acids. This sequence is determined by the sequence of nucleotides in the RNA. The nucleotides are considered three at a time. Each such triple results in addition of one specific amino acid to the protein being generated. The ...
A book or movie has three basic parts: a beginning, middle, and end. Translation has pretty much the same three parts, but they have fancier names: initiation, elongation, and termination. Initiation ("beginning"): in this stage, the ribosome gets together with the mRNA and the first tRNA so translation can begin.

Apr 30, 2024 · Translation takes place on ribosomes —complex particles in the cell that contain RNA and protein. In prokaryotes (organisms that lack a nucleus) the ribosomes are loaded onto the mRNA while transcription is still ongoing. The mRNA sequence is read three bases at a time from its 5’ end toward its 3’ end, and one amino acid is added to the ...
