True Statements are

A. Some genetic diseases may be caused by the substitution of only one incorrect amino acid in a protein.

as amino acids code for protein so, change in one anino acid results in formation of different protein and hence different product

B. A frameshift mutation affects only the codon directly after the addition or deletion.

this type of genetic mutation caused by insertions or deletions of a number of nucleotides in a DNA sequence

C. A change in DNA sequence may change the pattern of protein folding, resulting in genetic disease.

a change in DNA results in different RNA which after translation produce different protein and different product

F. Mutations can result from spontaneous events or external mutagens.

mutagens such as radioactive substances, x-rays, ultraviolet radiation cause certain type of cancers.

False statements are

D. It is possible for the substitution of one base for another to have no effect on an organism.

even change in sigle base results in alteration of amino acids

E. An error in an RNA sequence can be passed on to offspring as a genetic disease.

Errors in DNA can be passed to offsprings because DNA is genetic material, not RNA.
