13. why do cells need both trna and mrna? (1 point) only mrna can be used to repair mistakes in the dna sequence. only trna bends into a shape that can carry specific amino acids. the trna in used on the ribosomes and the mrna is used in the nucleus. the mrna brings information to the nucleus for the trna to use. 14. (03.06 lc) mutation does not always affect the evolution of a species because (1 point) not all mutations are inherited not all mutations are beneficial not all mutations cause visible change not all mutations affect an entire species 15. (03.06 mc) a chromosome that is exposed to a mutagen breaks into two pieces. a portion off one of the ends is removed before the two pieces rejoin. the mutation that occurs is (1 point) deletion duplication inversion non-disjunction 16. (03.06 mc) which of the following mutations is least likely to develop into a cancerous tumor? (1 point) a non-disjunction mutation a chromosomal deletion mutation a inversion chromosomal mutation a single point mutation 17. (03.06 mc) the mutagens that result in cancer damage dna by (1 point) destroying the cell's p53 gene directly thereby increasing cell production weakening the dna strand or interfering with base paring altering the cell's ph and allowing increased cell production becoming a virus that attacks dna directly, impairing duplication
