What is the site of protein synthesis quizlet?
What is the site of protein synthesis quizlet?
Ribosomes
What is the first step of protein synthesis called?
Transcription
What is the function of protein synthesis?
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.
How do you make protein synthesis?
The molecule of mRNA provides the code to synthesize a protein. In the process of translation, the mRNA attaches to a ribosome. Next, tRNA molecules shuttle the appropriate amino acids to the ribosome, one-by-one, coded by sequential triplet codons on the mRNA, until the protein is fully synthesized.
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 end result of 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. Polypeptide chains are formed during the translation process of protein synthesis.
Why does a human body need proteins?
Every cell in the human body contains protein. The basic structure of protein is a chain of amino acids. You need protein in your diet to help your body repair cells and make new ones. Protein is also important for growth and development in children, teens, and pregnant women.
What is the end result and purpose of protein synthesis?
Answer and Explanation: The end result of translation in protein synthesis is a newly made protein. During transcription, DNA is copied to messenger RNA (mRNA) in the…
What converts mRNA into a protein?
tRNA uses (anticodons/codons) to match to the mRNA. (Translation/Transcription) converts mRNA into a protein. 18. Translation takes place in the cytoplasm/nucleus).
Which provides the master code needed for protein synthesis?
DNA
What is the role tRNA in protein synthesis?
The overall role of tRNA in protein synthesis is to decode a specific codon of mRNA, using its anticodon, in order to transfer a specific amino acid to the end of a chain in the ribosome.
How does translation work in protein synthesis?
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.
Which of these is the primary site of protein synthesis?
Ribosomes are the site of protein synthesis, and they convert the coded information in messenger RNA (mRNA) into an actual protein molecule. The mRNA molecule carries the message contained in your DNA to the ribosome.
What must occur for protein translation to begin?
A water molecule must be added to the protein chain. A peptide bond must form between subunits of mRNA. The amino acid Cys must be picked up by tRNA.
Which provides the master code needed for protein synthesis quizlet?
mRNA is created by using a DNA template. mRNA codons are joined by tRNA anticodons to assemble amino acids to form a protein.
Which of these is the primary site of protein synthesis mitochondria cytoplasm nucleus ribosomes?
Explanation: Ribosome is a sub cellular structure, that is involved in protein synthesis. Mitochondria is a sub cellular structure, where cellular respiration takes place, therefore it is called the energy house of the cell.
What nucleic acid moves the code for protein synthesis?
Ribonucleic Acid
What is the function of RNA polymerase in protein synthesis?
RNA polymerases transcribe the information in DNA into RNA molecules that have a variety of functions, including messenger RNA (mRNA; codes for proteins), and non-coding RNAs such as transfer RNA (tRNA; transports amino acids to the ribosome for protein synthesis), ribosomal RNA (rRNA; helps catalyze protein synthesis …
What is the role of codon in protein synthesis?
A codon is a sequence of three DNA or RNA nucleotides that corresponds with a specific amino acid or stop signal during protein synthesis. Codons provide the key that allows these two languages to be translated into each other. …
How is ATP used in protein synthesis?
During protein synthesis, ATP (Adenosine Triphosphate) is used for adding a certain amino acid to a transfer RNA (tRNA).
How much ATP is required for protein synthesis?
The ATP required for protein biosynthesis is therefore 4 x 47.85 = 191.4 moles x 10-4 per g cells.
