The first codon of an mRNA molecule is a start codon. This signals the beginning of translation. The anti-codons and codons match up and form complementary base pairs.
The process of translation can be seen as the decoding of instructions for making proteins, involving mRNA in transcription as well as tRNA. The genes in DNA encode protein molecules, which are ...
Apr 8, 2024 · Translation of DNA. Translation is the process by which the genetic code contained within a messenger RNA (mRNA) molecule is decoded to produce a specific sequence of amino acids in a polypeptide chain. It occurs in the cytoplasm following DNA transcription and, like transcription, has three stages: initiation, elongation, and termination.

RNA and DNA are very similar molecules. They are both nucleic acids (one of the four molecules of life), they are both built on a foundation of nucleotides and they both contain four nitrogenous bases that pair up. A strand of DNA contains a chain of connecting nucleotides. Each nucleotide contains a sugar, and a nitrogenous base and a phosphate gr...
Transcription is the process of producing a strand of RNA from a strand of DNA. Similar to the way DNA is used as a template in DNA replication, it is again used as a template during transcription. The information that is stored in DNA molecules is rewritten or ‘transcribed’ into a new RNA molecule.
Translation is the process where the information carried in mRNA molecules is used to create proteins. The specific sequence of nucleotides in the mRNA molecule provides the code for the production of a protein with a specific sequence of amino acids. Much like how RNA is built from many nucleotides, a protein is formed from many amino acids. A cha...
No comments yet. (1) Translation begins when a ribosome (gray) docks on a start codon (red) of an mRNA molecule in the cytoplasm. (2) Next, tRNA molecules attached to amino acids (spheres) dock at ...
Jul 31, 2022 · Amazingly, the E. coli translation apparatus takes only 0.05 seconds to add each amino acid, meaning that a 200-amino acid protein can be translated in just 10 seconds. Figure 2. Translation begins when an initiator tRNA anticodon recognizes a codon on mRNA. The large ribosomal subunit joins the small subunit, and a second tRNA is recruited.

These triplets are called stop codons. Another codon, AUG, also has a special function. In addition to specifying the amino acid methionine, it also serves as the start codon to initiate translation. The reading frame for translation is set by the AUG start codon near the 5' end of the mRNA. The genetic code is universal.
