14. Some weed killers, insecticides, and food additives alter the DNA of certain cells. Because of this effect, these substances are known as 1) auxins meristems 2) mutagens autosomes 20. The genetic code of a DNA molecule is determined by a specific sequence of 1) ATP molecules 3) chemical bonds 2) sugar molecules molecular bases 21. What determines the kind of genes an organism possesses? type of amino acids in the cells of the organism 2) sequence of the subunits A, T, C,and G in the DNA of the organism 3) size of simple sugar molecules in the organs of the organism shape of the protein molecules in the organelles of the organism

Question 11 Choose all the ways that a chemical can cause a genetic mutation. - It can cause a nucleotide substitution - It can cause RNA to fold around DNA - It can cause errant numbers of nucleotides to be added in DNA - It can cause structural changes in DNA that lead to mutation - It can cause DNA be degraded - It can cause RNA to be degraded Question 6 Trinucleotides are really just: - A codon that will be read and converted into a single amino acid in a protein sequence - A piece of DNA that has no determined function, like an intron - Bits of DNA left over after transcription - Cellular waste product
