Which best summarizes the process of protein synthesis?
RNA moves DNA code to ribosomes for protein synthesis is the best way to summarize the process of protein synthesis…
What summarizes the process of protein synthesis?
Protein synthesis is the process by which cells make proteins. It happens in two stages: Transcription and translation… Translation takes place on the ribosome, which is composed of rRNA and protein. During translation, the instructions in the mRNA are read, and the tRNA brings the correct amino acid sequence to the ribosome.
Which statement best summarizes the role of DNA in tests of protein synthesis?
Which of the following best summarizes the role of DNA in protein synthesis? DNA contains the genetic code that determines the amino acid sequence of proteins.
What is the name of the protein synthesis process?
This process is called protein synthesis and it actually consists of two processes – Transcription and translation . In eukaryotic cells, transcription occurs in the nucleus. During transcription, DNA is used as a template to make messenger RNA (mRNA) molecules.
What is the process of protein?
protein synthesis is the process of producing protein molecules. In biological systems, it is involved in amino acid synthesis, transcription, translation and post-translational events. …in translation, amino acids are linked together in a specific order according to the genetic code.

What are the 7 steps of protein synthesis?
What are the 7 steps of protein synthesis?
- DNA unwinds in the nucleus.
- mRNA nucleotides transcribe complementary DNA messages.
- mRNA leaves the nucleus and enters the ribosome.
- mRNA attaches to the ribosome and reads the first codon.
- tRNA introduces the appropriate amino acids from the cytoplasm.
- The second tRNA brings in the new amino acid.
What is the first step in protein synthesis?
Protein synthesis is the process the body uses to make protein.The first step in protein synthesis is called Transcribe. It occurs in the nucleus. During transcription, mRNA transcribes (replicates) DNA.
What are the two main steps in protein synthesis?
It consists of two main steps: Transcription and translation. Transcription and translation together are called gene expression. During transcription, the information stored in a gene’s DNA is passed to a similar molecule called RNA (ribonucleic acid) in the nucleus of the cell.
What is the first step in the protein synthesis worksheet?
The first step in protein synthesis is called Transcribe.

Which best summarizes the role of DNA in protein production?
Which best summarizes the role of DNA in protein production? … DNA transports amino acids to the ribosome to make proteins. DNA contains instructions for making proteins.
What must happen to protein translation?
What must happen to protein translation? Water molecules must be added to the protein chain. Peptide bonds must be formed between the subunits of the mRNA. The amino acid Cys must be picked up by the tRNA.
Which one is the main site of protein synthesis?
Ribosome are sites of protein synthesis, and they convert the encoded information in messenger RNA (mRNA) into actual protein molecules.
What are the three components required for protein synthesis?
Basic experimental work is mainly performed using cell-free bacterial extracts that contain all components necessary for protein synthesis except mRNA (i.e., tRNA, ribosomes, amino acids and energy-rich nucleotides ATP and GTP).
What are the six steps of protein synthesis?
The messenger molecule (mRNA) carries the DNA copy to the cytoplasm. The messenger molecule (mRNA) passes through the ribosome 3 bases at a time. Transfer molecules called tRNAs bring the correct AA (amino acids) from the cytoplasm to the ribosome. Transfer molecules (tRNAs) release amino acids (AA) on the ribosome.
Where does protein synthesis take place?
Ribosome It is the site of protein synthesis in cells. Cells have many ribosomes, and the exact number depends on how active a particular cell is at synthesizing proteins.
What is the final step in protein synthesis?
The final step in protein synthesis is termination. During termination, the ribosome reads the stop codon in the mRNA.
What are the steps of transcription?
Transcription occurs in three steps: start, extend and end. These steps are shown in Figure 2. Figure 2. Transcription occurs in three steps – initiation, elongation, and termination – all shown here.
What must happen before a protein can function?
protein folding
A functional protein is not a long, stretched chain of amino acids, but a complex three-dimensional structure. That is, Every protein must fold into a specific shape or conformation in order to perform its function in the cell.
What is the second step in protein synthesis called?
Transcriptional steps of protein synthesis. translate is the second step in protein synthesis. As shown below. Translation takes place on ribosomes in the cytoplasm. During translation, the genetic code in mRNA is read to make proteins.
How many codons are required for each amino acid?
three codons Three amino acids need to be specified. Codons can be described as messengers located on messenger RNA (mRNA).
Which of the following is the main site of quizlet for protein synthesis?
protein synthesis in Ribosome.
Why is the ribosome known as the site of protein synthesis?
The ribosome is the only organelle, Involved in protein synthesis. Therefore, they are called the protein factories of the cell. Ribosomes synthesize proteins by collecting amino acids and assembling them into protein chains.
What eukaryotic organelle is the main site of protein synthesis?
This is Ribosome. It functions in biological protein synthesis by linking amino acids together in a manner prescribed by mRNA. Small subunits read RNA, and large subunits connect amino acids to form polypeptide chains.
What are the four steps of translation?
Translation takes place in four stages: Activate (ready), initiate (start), extend (extend), and terminate (stop). These terms describe the growth of chains of amino acids (polypeptides). Amino acids are brought to the ribosome and assembled into proteins.
