Which is the site of protein synthesis

What is the site of protein synthesis quizlet?

Site of protein synthesis . Consists of large and small subunits (both are synthesized in the nucleolus and are assembled in the cytoplasm).

Where is the site of synthesis?

In eukaryotes, the synthesis and assembly of rRNAs occurs in the nucleolus. Ribosomes exist in the cytoplasm in prokaryotes and in the cytoplasm and on rough endoplasmic reticulum membranes in eukaryotes.

Is are the site of protein synthesis in the cytoplasm?

The site of protein synthesis in the cytoplasm is the ribosome. Protein synthesis starts in the nucleus, where transcription occurs.

Which of these is the primary site of protein synthesis quizlet?

Ribosomes use the information in mRNA to direct the synthesis of a protein . Carries amino acids. Large RNA- protein complexes that are composed of two subunits, often bound to ER, and are the sites of protein synthesis .

Which statement is the first step of protein synthesis?

The first step of protein synthesis is called Transcription . It occurs in the nucleus. During transcription , mRNA transcribes (copies) DNA. DNA is “unzipped” and the mRNA strand copies a strand of DNA.

Where does protein synthesis occur?

Protein synthesis occurs in the cytoplasm on ribonucleoprotein particles, the ribosomes.

What is the most active site of protein synthesis?

The most active site of protein synthesis is the Ribosome .

What is the synthesis of protein?

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.

What triggers protein synthesis?

Protein ingestion and resistance exercise both stimulate the process of new muscle protein synthesis (MPS) and are synergistic when protein consumption follows exercise. In healthy persons, changes in MPS are much greater in their influence over net muscle gain than changes in muscle protein breakdown (MPB).

What is the purpose of protein synthesis?

Lesson Summary Protein synthesis is the process all cells use to make proteins, which are responsible for all cell structure and function. There are two main steps to protein synthesis. In transcription, DNA is copied to mRNA, which is used as a template for the instructions to make protein.

What would happen without protein synthesis?

The Importance of Protein Ribosomes contain molecules called RNA. These molecules hold all of the instructions necessary for the ribosomes to carry out protein synthesis or the process of creating proteins . Without these proteins , the DNA repairs would not happen , leading to mutations and problems such as cancer.

Which organelle is the primary site of protein production?

A ribosome is an organelle that serves as the site of protein synthesis. It is composed of two ribosomal RNA subunits that wrap around mRNA to start the process of translation, followed by protein synthesis. Smooth ER (SER) lacks these ribosomes .

Which best summarizes the process of protein synthesis?

RNA moves the DNA code to the ribosomes for protein synthesis is the best way to summarize the process of protein synthesis .
