In the process of protein synthesis within the cell, the correct sequence of nucleic acids involved is as follows:
a. DNA → mRNA → rRNA → tRNA
Here's a step-by-step breakdown of the process:
1. DNA (Deoxyribonucleic Acid): It carries the genetic information necessary for protein synthesis.
2. mRNA (Messenger Ribonucleic Acid): It carries the genetic information from DNA to the ribosome, where protein synthesis occurs.
3. rRNA (Ribosomal Ribonucleic Acid): It is a structural component of ribosomes, which are the protein-building factories of the cell.
4. tRNA (Transfer Ribonucleic Acid): It carries specific amino acids to the ribosome based on the codons (triplets of nucleotides) on the mRNA.
Therefore, the correct order of nucleic acids involved in protein synthesis is DNA → mRNA → rRNA → tRNA. This sequence showcases the flow of genetic information from DNA to the production of proteins in a coordinated and precise manner.
