What is the second step of protein synthesis called
Where is second step of protein synthesis?
ribosome
Translation is the second step in protein synthesis. It is shown in Figure below. Translation takes place at a ribosome in the cytoplasm. During translation, the genetic code in mRNA is read to make a protein.
What is the second step of synthesis called?
mRNA Translation Is The Second Step Of Protein Synthesis
The production of proteins happens during the second step of protein synthesis process – the Translation.
What are the steps of protein synthesis?
It includes three steps: initiation, elongation, and termination. After the mRNA is processed, it carries the instructions to a ribosome in the cytoplasm. Translation occurs at the ribosome, which consists of rRNA and proteins.
What is the 2nd step of translation?
The second stage is called chain elongation. During this stage, additional amino acids are progressively added. The methionine-bearing initiator tRNA sits on a site of the ribosome called the P (peptidyl) site.
What is the 2nd step of transcription?
Once RNA polymerase is in position at the promoter, the next step of transcription—elongation—can begin. Basically, elongation is the stage when the RNA strand gets longer, thanks to the addition of new nucleotides.
What are the two steps of protein synthesis quizlet?
It has two major steps: first translation, then transcription.
Why is protein synthesis a two part process?
Protein synthesis is a two-part process because it allows for more precise control.
What occurs during the stage of protein synthesis called translation?
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 steps of protein synthesis in order quizlet?
Terms in this set (5)
- FIRST step. DNA unzips between its pairs, then one of the strands of DNA directs the production of mRNA.
- SECOND step. A ribosome attaches to mRNA in the cytoplasm, specific amino acids are attached to the tRNA.
- THIRD step. Molecules of tRNA and amino acids attach to mRNA.
- FOURTH step. …
- FIFTH step.
Where does each step of protein synthesis occur in the cell quizlet?
Ribosomes are the place where Protein Synthesis takes place.
What is a codon and what is its role 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. DNA and RNA molecules are written in a language of four nucleotides; meanwhile, the language of proteins includes 20 amino acids.
What are the 5 stages of protein synthesis?
5 Major Stages of Protein Synthesis (explained with diagram) |…
- (a) Activation of amino acids:
- (b) Transfer of amino acid to tRNA:
- (c) Initiation of polypeptide chain:
- (d) Chain Termination:
- (e) Protein translocation:
What is the last step of protein synthesis?
Answer and Explanation: The last step in protein synthesis is termination. During termination, the ribosome reads the stop codon in the mRNA.
What is the first step of protein synthesis quizlet?
The first stage of protein synthesis where the information on a section of DNA (a gene) is copied by making a mRNA molecule from the DNA.
What are the 4 steps of protein synthesis in order?
The major steps are:
- (a) Activation of amino acids:
- (b) Transfer of amino acid to tRNA:
- (c) Initiation of polypeptide chain:
- (d) Chain Termination:
- (e) Protein translocation:
What is the start codon called?
AUG
The ribosome reads the mRNA in three nucleotide codons, beginning with the start codon, AUG, which codes for the amino acid methionine. The order of the bases within the codons determines which amino acid will be added to the growing protein by the ribosome.
