Quick Answer: What Is The Second Step Of Translation?

What is the process of translation?

Translation is the process of translating the sequence of a messenger RNA (mRNA) molecule to a sequence of amino acids during protein synthesis.

The genetic code describes the relationship between the sequence of base pairs in a gene and the corresponding amino acid sequence that it encodes..

What are the major stages of translation process?

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.

What is the first step of translation?

The process of translation can be broken down into three stages. The first stage is initiation. In this step, a special “initiator” tRNA carrying the amino acid methionine binds to a special site on the small subunit of the ribosome (the ribosome is composed of two subunits, the small subunit and the large subunit).

How many codons are needed for 3 amino acids?

Three codonsThree codons are needed to specify three amino acids. Codons can be described as messengers that are located on the messenger RNA (mRNA).

What is needed for translation?

The Protein Synthesis Machinery. In addition to the mRNA template, many molecules and macromolecules contribute to the process of translation. Translation requires the input of an mRNA template, ribosomes, tRNAs, and various enzymatic factors.

What are the 4 steps of translation?

Translation happens in four stages: activation (make ready), initiation (start), elongation (make longer) and termination (stop). These terms describe the growth of the amino acid chain (polypeptide).

What is the second step in transcription?

Step 2: Elongation RNA polymerase reads the unwound DNA strand and builds the mRNA molecule, using complementary base pairs. There is a brief time during this process when the newly formed RNA is bound to the unwound DNA. During this process, an adenine (A) in the DNA binds to an uracil (U) in the RNA.

What are the 5 steps of translation?

Translation (biology)Initiation: The ribosome assembles around the target mRNA. The first tRNA is attached at the start codon.Elongation: The tRNA transfers an amino acid to the tRNA corresponding to the next codon. … Termination: When a stop codon is reached, the ribosome releases the polypeptide.

What is a codon?

A codon is a trinucleotide sequence of DNA or RNA that corresponds to a specific amino acid. The genetic code describes the relationship between the sequence of DNA bases (A, C, G, and T) in a gene and the corresponding protein sequence that it encodes. The cell reads the sequence of the gene in groups of three bases.

What are the steps of the central dogma?

The central dogma of molecular biology describes the two-step process, transcription and translation, by which the information in genes flows into proteins: DNA → RNA → protein. Transcription is the synthesis of an RNA copy of a segment of DNA.

What is the second step of initiation in translation?

There are three important steps to the process of translation. There’s a beginning step, called initiation, a middle step, called elongation, and a final step, called termination.

What comes first transcription or translation?

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).

Where is RNA located in a cell?

There are two types of nucleic acids which are polymers found in all living cells. Deoxyribonucleic Acid (DNA) is found mainly in the nucleus of the cell, while Ribonucleic Acid (RNA) is found mainly in the cytoplasm of the cell although it is usually synthesized in the nucleus.

What are the 3 steps of translation?

Translation of an mRNA molecule by the ribosome occurs in three stages: initiation, elongation, and termination. During initiation, the small ribosomal subunit binds to the start of the mRNA sequence.
