Question

All living cells, regardless of organism, convey genetic information in a specific order. What is that order?

A. Protein --> RNA --> DNA
B. DNA --> RNA --> protein
C. RNA --> DNA --> protein
D. Protein --> DNA --> RNA

Answer 1

The correct order of genetic information flow in cells is DNA to RNA to protein, as per the Central Dogma of molecular biology, which involves transcription and translation.

Step-by-step explanation:

The order in which genetic information is conveyed in all living cells is DNA to RNA to protein. This sequence is central to molecular biology and is known as the Central Dogma. It begins with transcription, where the DNA code is used to create messenger RNA (mRNA). Following this, translation occurs, which is the process where the mRNA sequence is used to produce a specific protein. Each three-nucleotide sequence of the mRNA, known as a codon, corresponds to one amino acid in the protein.
