What are the steps of DNA translation?

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.

What usually terminates the process of translation?

Translation ends in a process called termination. Termination happens when a stop codon in the mRNA (UAA, UAG, or UGA) enters the A site. After the small and large ribosomal subunits separate from the mRNA and from each other, each element can (and usually quickly does) take part in another round of translation.

What is the difference between prokaryotic and eukaryotic translation?

Eukaryotic and Prokaryotic translations are involved in protein synthesis. The key difference between eukaryotic and prokaryotic translation is that eukaryotic translation and transcription is an asynchronous process whereas prokaryotic translation and transcription is a synchronous process.

What is the end result of translation?

amino acid sequence
The amino acid sequence is the final result of translation, and is known as a polypeptide. Polypeptides can then undergo folding to become functional proteins. All enzymes are proteins, but not all proteins go on to become enzymes; some serve other functions.

Where does translation take place on a DNA strand?

Codons to amino acids. At the other end, called the 3’ end, the hydroxyl of the last nucleotide added to the chain is exposed. Often, molecular processes can only take place in a certain direction along a DNA or RNA strand. For instance, in translation, the mRNA is always read from the 5′ end towards the 3′ end.

What are the steps in the translation of a protein?

These include: 1 A ribosome (which comes in two pieces, large and small) 2 An mRNA with instructions for the protein we’ll build 3 An “initiator” tRNA carrying the first amino acid in the protein, which is almost always methionine (Met) More

How is transcription the first step in gene expression?

In biology, transcription is the process of copying out the DNA sequence of a gene in the similar alphabet of RNA. Transcription is the first step in gene expression, in which information from a gene is used to construct a functional product such as a protein. The goal of transcription is to make a RNA copy of a gene’s DNA sequence.

How does the initiation of translation take place?

Initiation. Inside your cells (and the cells of other eukaryotes), translation initiation goes like this: first, the tRNA carrying methionine attaches to the small ribosomal subunit. Together, they bind to the 5′ end of the mRNA by recognizing the 5′ GTP cap (added during processing in the nucleus).
