Question

The central dogma of protein synthesis is

• A. DNA $\to$ DNA $\to$ mRNA $\to$ Protein
• B. mRNA $\to$ gRNA $\to$ DNA $\to$ Protein
• C. gRNA $\to$ DNA $\to$ mRNA $\to$ Protein
• D. DNA $\to$ gRNA $\to$ mRNA $\to$ Protein

Answer 1

The correct option is D DNA $\to$ gRNA $\to$ mRNA $\to$ Protein

DNA forms the basis of the central dogma from where the process of protein synthesis starts.

gRNA or the guide RNA is the RNAs that guide the insertion or deletion of uridine residues into mitochondrial mRNA.

DNA is basically converted to mRNA through the process called transcription.

Then this mRNA is translated into proteins through triplet coding where a codon (sequence of trinucleotide) codes a particular amino acid. This process is known as translation.

So, the correct option is 'DNA → gRNA → mRNA → Protein'.
