What Are The 5 Steps Of Translation In Biology? - Fixanswer

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). Amino acids are brought to ribosomes and assembled into proteins.

What are the steps of translation in biology?

Translation of an mRNA molecule by the ribosome occurs in three stages:

initiation, elongation, and termination

.

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 is the first step of translation?

Translation is generally divided into three stages: initiation, elongation, and termination (Figure 7.8). In both prokaryotes and eukaryotes the first step of the initiation stage is

the binding of a specific initiator methionyl tRNA and the mRNA to the small ribosomal subunit

.

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 is the last step 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. Stop codons are recognized by proteins called release factors, which fit neatly into the P site (though they aren’t tRNAs).

What is the main function of RNA *?

The central dogma of molecular biology suggests that the primary role of RNA is

to convert the information stored in DNA into proteins

.

What happens during translation?

During translation,

ribosomal subunits assemble together like a sandwich on the strand of mRNA

, where they proceed to attract tRNA molecules tethered to amino acids (circles). A long chain of amino acids emerges as the ribosome decodes the mRNA sequence into a polypeptide, or a new protein.

What are the steps of translation in prokaryotes?

Activation of aminoacids: The activation of aminoacids take place in cytosol. The activation of aminoacids is catalyzed by their aminoacyl tRNA synthetases. …
Initiation:
Elongation: i. …
Termination: The peptide bond formation and elongation of polypeptide continues until stop codon appear on A-site.

What is the final product of translation?

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.

What is the result of translation?

The molecule that results from translation is

protein —

or more precisely, translation produces short sequences of amino acids called peptides that get stitched together and become proteins. During translation, little protein factories called ribosomes read the messenger RNA sequences.

What are the 3 main steps of transcription?

It involves copying a gene’s DNA sequence to make an RNA molecule. Transcription is performed by enzymes called RNA polymerases, which link nucleotides to form an RNA strand (using a DNA strand as a template). Transcription has three stages:

initiation, elongation, and termination

.

What enzyme makes copies of DNA?

DNA polymerase (DNAP)

is a type of enzyme that is responsible for forming new copies of DNA, in the form of nucleic acid molecules.

What is the process of reverse transcription?

A reverse transcriptase (RT) is an enzyme used to generate complementary DNA (cDNA) from an RNA template, a process termed reverse transcription. … Collectively, these activities enable the

enzyme to convert single-stranded RNA into double-stranded cDNA

.
