Question

question 14

1. which of the following is the proper sequence of events in protein synthesis?

protein → dna → mrna
dna → protein → mrna
dna → mrna → protein
mrna → dna → protein

Explanation:

Protein synthesis starts with DNA. DNA undergoes transcription to form mRNA. Then, mRNA is translated to produce protein. The first two options have incorrect sequences as protein cannot directly come from DNA without mRNA intermediate (in normal protein - synthesis pathway, not considering reverse processes like reverse - transcription which is not protein synthesis). The last option has mRNA coming before DNA which is wrong as DNA is the template for mRNA synthesis in protein synthesis.

Answer:

DNA → mRNA → protein
