Asub-group of individuals who suffer from a particular disease exhibit a base-pair substitution in the messenger rna for a protein related to the disease. a researcher concludes that this form of the disease result is heritable. which of the following, if true, would justify this conclusion?

a)there is no correlation between the incidence of the base-pair substitution and the incidence of the disease in the population.

b)the base-pair substitution does not change the amino acid that corresponds to the codon.

c)the same group of individuals exhibits a corresponding base-pair substitution in the dna.

d)the base-pair substitution in the mrna occurs in an intron.

In eukaryotes, genetic information is passed to the next generation by processes that include mitosis or meiosis. which of the explanations identifies the correct process and supports the claim that heritable information is passed from one generation to another? a. mitosis, followed by cytokinesis, produces daughter cells that are genetically different from the parent cell, thus insuring variation within the population. b. during mitosis, dna replication occurs twice within the cell cycle to insure a full set of chromosomes within each of the daughter cells produced. c. in asexual reproduction, a single individual is the sole parent and passes copies of its genes to its offspring without the fusion of gametes. d. single-celled organisms can fuse their cells, reproducing asexually through mitosis to form new cells that are not identical to the parent cell.
