Question

question 5 of 10
which best describes the flow of genetic information?
a. genetic information cannot be transmitted outside the nucleus.
b. genetic information is carried only by dna.
c. genetic information flows from dna to rna to protein.
d. genetic information flows from gene to allele to protein.

Explanation:

The central dogma of molecular biology states that genetic information flows from DNA (through transcription) to RNA and then (through translation) to protein. Option A is incorrect as mRNA (carrying genetic info from DNA) can leave the nucleus. Option B is wrong because in some viruses, RNA carries genetic information. Option D is incorrect as alleles are variants of genes and the flow is not from gene to allele to protein.

Answer:

C. Genetic information flows from DNA to RNA to protein.
