According to the gene-chromosome theory, which statement is true?
a change in the sequence of amino acids determined by the gene
Genes are arranged in a linear sequence on a chromosome.
a gene mutation
sequence of bases in the organism’s DNA
result in different genetic sequences
increase the rate of gene mutations
sequence of subunits in DNA
radioactive substances in the environment
Although genetic mutations may occur spontaneously in organisms, the incidence of such mutations may be increased by
a change in the sequence of amino acids determined by the gene
