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

C= genetic information flows from DNA to RNA to proteins.

The genetic information inherited by an organism by the biological process of heredity is by the gene. The gene is the physical and functional unit present as a segment of DNA. The DNA consisting of gene transcribe in order to produce RNA. The RNA is converted into protein by translation. The type of protein produce will reflect the genotypic and phenotypic trait produce in an organism. Hence, the genetic information flows from DNA to RNA to proteins.

option a is correct i.e.

explanation:

in context to the membrane of nerve impulse, the outer membrane of neuron is semi permeable that is only sodium ions can pass through the membrane i.e. smaller ions can pass through the membrane while larger ions cannot pass through it.
