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 end result in protein synthesis?
The result of protein synthesis is a chain of amino acids that have been attached, link by link, in a specific order. This chain is called a polymer or polypeptide and is constructed according to a DNA-based code. … The difference between a protein and a polypeptide is the form.
What is the end result of translation?
When the ribosome reaches a stop codon, it releases the mRNA strand and 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.
What happens after translation in protein synthesis?
After being translated from mRNA, all proteins start out on a ribosome as a linear sequence of amino acids. This linear sequence must “fold” during and after the synthesis so that the protein can acquire what is known as its native conformation.What is the outcome 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.
Which of the following events occurs during the translation phase of protein synthesis?
Translation occurs at the ribosome, which consists of rRNA and proteins. In translation, the instructions in mRNA are read, and tRNA brings the correct sequence of amino acids to the ribosome. Then, rRNA helps bonds form between the amino acids, producing a polypeptide chain.
What happens translation?
In biology, the process by which a cell makes proteins using the genetic information carried in messenger RNA (mRNA). The mRNA is made by copying DNA, and the information it carries tells the cell how to link amino acids together to form proteins.
What is the end result of translation in protein synthesis quizlet?
What is the end result of Translation? One protein or a long chain of amino acids.What happens to the ribosome after translation?
During translation, the two subunits come together around a mRNA molecule, forming a complete ribosome. The ribosome moves forward on the mRNA, codon by codon, as it is read and translated into a polypeptide (protein chain). Then, once translation is finished, the two pieces come apart again and can be reused.
What is the result of this mutation during the translation process?The outcome of a frameshift mutation is complete alteration of the amino acid sequence of a protein. This alteration occurs during translation because ribosomes read the mRNA strand in terms of codons, or groups of three nucleotides. These groups are called the reading frame.
Article first time published onWhat results from the process of translation quizlet?
What results from the process of translation? … Bacteria can begin translation before transcription has terminated. You just studied 22 terms!
What is accomplished in translation?
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 is translation describe the process of protein synthesis?
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.
How are proteins being synthesized during translation?
In translation, polypeptides are synthesized using mRNA sequences and cellular machinery, including tRNAs that match mRNA codons to specific amino acids and ribosomes composed of RNA and proteins that catalyze the reaction.
Where does translation occur in the cell?
Where Translation Occurs. Within all cells, the translation machinery resides within a specialized organelle called the ribosome. In eukaryotes, mature mRNA molecules must leave the nucleus and travel to the cytoplasm, where the ribosomes are located.
Which does the termination of translation require?
Answer: The termination of translation requires GTP, stop codon, and release factors.
Which step does not occur in translation?
c. Chain termination; Once the termination codon is reached, release factors and GTP help in this process. The subunits of ribosome separate and amino acid chain is released.
Which of the following changes is associated with the post translational processing of a protein?
Post-translational modifications change the chemical nature of the polypeptide chain through alterations to amino acid residues. Post-translational modifications take place in the ER and include folding, glycosylation, multimeric protein assembly and proteolytic cleavage leading to protein maturation and activation.
What terminates the formation of a polypeptide chain during protein synthesis in cells?
Behind the first ribosome, up to 50 additional ribosomes can bind to the mRNA molecule forming a polysome, this enables simultaneous synthesis of multiple identical polypeptide chains. Termination of the growing polypeptide chain occurs when the ribosome encounters a stop codon (UAA, UAG, or UGA) in the mRNA molecule.
What happens at the ribosome *?
Ribosomes receive information from the cell nucleus and construction materials from the cytoplasm. Ribosomes translate information encoded in messenger ribonucleic acid (mRNA). They link together specific amino acids to form polypeptides and they export these to the cytoplasm.
What happens to the tRNA after translation?
The first tRNA transfers its amino acid to the amino acid on the newly arrived tRNA, and a chemical bond is made between the two amino acids. The tRNA that has given up its amino acid is released. It can then bind to another molecule of the amino acid and be used again later in the protein-making process.
What is created at the end of the transcription stage of protein synthesis?
After termination, transcription is finished. An RNA transcript that is ready to be used in translation is called a messenger RNA (mRNA). In bacteria, RNA transcripts are ready to be translated right after transcription.
What is the result of transcription in protein synthesis quizlet?
what is the end result of transcription? DNA is converted to a strand of mRNA to be translated in the ribosome.
What is the final product of transcription?

How mutations affect protein synthesis?
Sometimes, gene variants (also known as mutations) prevent one or more proteins from working properly. By changing a gene’s instructions for making a protein, a variant can cause a protein to malfunction or to not be produced at all.
What can mutations result in?
Most mutations are not harmful, but some can be. A harmful mutation can result in a genetic disorder or even cancer. Another kind of mutation is a chromosomal mutation. Chromosomes, located in the cell nucleus, are tiny threadlike structures that carry genes.
How do mutations affect transcription and translation?
Mutations that happen during Transcription and Translation. What happens if there is a mistake (mutation) in the DNA code? Possibly proteins won’t be made or are made improperly. If the mutations occur in the gametes, the offspring’s DNA will be affected positively, negatively, or neutrally.
What happens during the process of translation of protein synthesis quizlet?
What happens during the process of translation? The cell uses information from messenger RNA to produce proteins. … codon on the mRNA and the anticodon on the tRNA to which the amino acid is attached.
What happens in translation quizlet?
What happens during translation? During translation, a ribosome uses the sequence of codons in mRNA to assemble amino acids into a polypeptide chain. The correct amino acids are brought to the ribosome by tRNA. … In most organisms the same amino acids are assigned to particular codons.
Which of the following can be translated into a protein?
Which of the following can be translated into protein? a) mRNA, tRNA, and rRNA are all translated into protein.
How the process of translation is helpful in synthesis of different types of proteins?
In translation, the amino acids are linked together in a particular order based on the genetic code. After translation, the newly formed protein undergoes further processing, such as proteolysis, post-translational modification, and protein folding.
