Which of the following is the site of translation

What is the site of translation?

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.

What is the site of translation quizlet?

Translation in the ribosome in the cytoplasm. Receives amino acids from nucleus to make proteins. The bond, or what makes the bonds, between the amino acids. Also known as tRNA, only a part of RNA, part of what happens during transcription in the nucleus.

What is translation and where does it occur?

Translation is the process by which a protein is synthesized from the information contained in a molecule of messenger RNA (mRNA). Translation occurs in a structure called the ribosome, which is a factory for the synthesis of proteins.

Are ribosomes the site of translation?

Ribosomes : Where the translation happens. Translation takes place inside structures called ribosomes , which are made of RNA and protein. Ribosomes organize translation and catalyze the reaction that joins amino acids to make a protein chain.

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

What are the 7 steps of translation?

Terms in this set ( 7 ) mRNA binds to the small subunit of the ribosome. tRNA with anticodon complementary to the first codon to be translated on the mRNA binds to the ribosome. a second tRNA with an anticodon complementary to the second codon on the mRNA then binds.

What occurs during protein synthesis?

Protein synthesis is the process in which cells make proteins . It occurs in two stages: transcription and translation. 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.

Are ribosomes the site where transcription takes place?

The mRNA formed in transcription is transported out of the nucleus, into the cytoplasm, to the ribosome (the cell’s protein synthesis factory). Here, it directs protein synthesis. Messenger RNA is not directly involved in protein synthesis − transfer RNA (tRNA) is required for this.

What holds base pairs together quizlet?

The sugars and phosphates make up the “handrails” (or “backbone”), and are held together by covalent bonds . Nitrogen bases are held together by hydrogen bonds in between the two strands. Complementary base pairing rules mean that adenine always pairs with thymine, and cytosine always pairs with guanine.

What happens during translation?

The entire process is called gene expression. In translation , messenger RNA (mRNA) is decoded in a ribosome, outside the nucleus, to produce a specific amino acid chain, or polypeptide. The polypeptide later folds into an active protein and performs its functions in the cell.

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.

What are the 5 steps of translation?

Translation (Protein Synthesis) Initiation . In this step the small subunit part of the ribosome attaches to the 5′ end of the mRNA strand. Elongation . Termination .

What is translation process?

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 6 steps of translation?

What are the Six Steps of Translation in Eukaryotes I. binding of mRNA to ribosome. (ii) Aminoacylation. ADVERTISEMENTS: (iii) Initiation . (iv) Elongation . Step I- Binding of incoming aminoacyl. (v) Termination. (vi) Post-translational modifications.

What is the site of protein synthesis?

Ribosomes are the sites in a cell in which protein synthesis takes place . Within the ribosome, the rRNA molecules direct the catalytic steps of protein synthesis — the stitching together of amino acids to make a protein molecule.
