Question

Which of the following best describes the flow of genetic information inside a cell?

a. protein --> RNA --> DNA
b. DNA --> RNA --> protein
c. RNA --> DNA --> protein
d. DNA --> protein --> RNA

Answer 1

The flow of genetic information inside a cell is DNA -> RNA -> protein

Step-by-step explanation:

The flow of genetic information inside a cell is best described as:

1. DNA --> RNA --> protein

This process is known as the Central Dogma of molecular biology. It involves the transcription of DNA into mRNA and the subsequent translation of mRNA into protein. DNA carries the genetic instructions, mRNA carries those instructions to the ribosomes, and ribosomes synthesize the proteins.
