Question

Put the following processes of protein synthesis in the correct order.

Answer 1

Correct sequential order for the following processes of protein synthesis are as follows:

• DNA strands unwind and separate
• mRNA copies DNA according to complimentary base pairing  
• mRNA leaves the nucleus

• tRNA’s anticodons bring amino acids to the corresponding mRNA codons at the ribosomes
• amino acids bind to each other making a polypeptide
• a stop codon is reached, the newly formed a protein is released to go do its job for the cell

Option A --> B --> C --> E --> D -->F

Explanation:

Protein synthesis involves three major steps which are Replication of DNA, which is then transcribed and then translated to form protein, so the steps are Replication, Transcription and Translation.

Firstly, the DNA is a double stranded molecule which needs to be unwind as a replica where one of the strand becomes the template strand and transcription of strand occurs with mRNA.

mRNA thus leaves the nucleus and reaches cytoplasm where translation takes places and the tRNA provides specific anti codons to the mRNA codons and the amino acids are formed.

All amino acids bind to each other in order to make a polypeptide and hence the protein molecule newly formed is released to the cell.
