How is translation used in protein synthesis?
Protein synthesis is accomplished through a process called translation. After DNA is transcribed into a messenger RNA (mRNA) molecule during transcription, the mRNA must be translated to produce a protein. In translation, mRNA along with transfer RNA (tRNA) and ribosomes work together to produce proteins.
What are the 4 steps to translation?
The four steps of translation are:
- Activation or charging of tRNA.
- Initiation – recognition of start codon, binding of ribosomal subunits to mRNA and formation of initiation complex with Met-tRNA at the P site.
- Elongation – peptide bond formation and growing of polypeptide chain.
What is translation in protein synthesis GCSE?
Protein synthesis consists of two stages – transcription and translation. In transcription the DNA code is read, and in translation the code is used to build up protein molecules. DNA is a triplet code. Each triplet, a group of three bases, codes for a specific amino acid.
What is translation in biology GCSE?
Translation – during which the mRNA attaches to the ribosome, which recruits tRNAs carrying amino acids in order to make a polypeptide.
What is translation and its steps?
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 are the stages in translation?
There are three major steps to translation: Initiation, Elongation, and Termination. The ribosome is made of two separate subunits: the small subunit and the large subunit. During initiation the small subunit attaches to the 5′ end of mRNA. It then moves in the 5′ → 3′ direction.

What is translation and transcription in protein synthesis?
Cell uses the genes to synthesize proteins. This is a two-step process. The first step is transcription in which the sequence of one gene is replicated in an RNA molecule. The second step is translation in which the RNA molecule serves as a code for the formation of an amino-acid chain (a polypeptide).
