Answer:

Since you didn't put answer choices, the answer you are looking for should be in the explanation.

Explanation:

Protein synthesis is needed to create new proteins for the cell. Proteins are essential because they perform functions for the cell, such as catalysis and communication, and form important structures like the cytoskeleton. It occurs in two stages: transcription and translation. Transcription is the transfer of genetic instructions in DNA to mRNA in the nucleus. It includes these steps:

(1) Activation of amino acids:

(2) Transfer of amino acid to tRNA:

(3) Initiation of polypeptide chain:

(4) Chain Termination:

(5) Protein translocation:

Answer:

mRNA strand is formed, mRNA is processed, polypeptide chain is formed, protein is modified

Explanation:

Here it is:

1. DNA is used as a template to create mRNA

 

2. mRNA molecule binds to a ribosome

 

3. tRNA binds to the ribosome (specific tRNAs bring individual amino acids reading mRNA codons)

 

4. Amino acids are bonded together to make a poly peptide

 

5. The ribosome releases both the mRNA molecule and the polypeptide ( when it encounters translation termination codon on mRNA).
