question 9 of 10
how does genetic information flow in nearly all cells?
a. protein→mrna→dna
b. dna→mrna→protein
c. mrna→dna→protein
d. mrna→protein→dna

Explanation:

In nearly all cells, genetic information flows from DNA (through transcription) to mRNA, and then from mRNA (through translation) to protein. This is the central dogma of molecular biology. DNA contains the genetic code, mRNA is the messenger that carries the code from DNA to the ribosomes, and proteins are synthesized based on the mRNA sequence. Options A, C, and D do not follow the correct order of the central dogma.

Answer:

B. DNA→mRNA→protein
