They induce the production of chemical y They improve or decrease the proofreading efficiency of DNA polymerase They result in more or less efficient movement. They result in a change in the genetic code ich statement is NOT true about DNA replication? It proceeds in a 5-to-3′ direction only One strand of new DNA is replicated faster than the other strand at the replication fork DNA can only replicate at one point on a chromosome at one time. substances, some of which are toxins and others are antibiotics 32 D. It occurs more rapidly in bacteria than in eukaryotes Mendel’s findings that the inheritance of one trait had no effect on the inheritance of another became known as the 33 law of dominance law of universal inheritance law of separate convenience law of independent assortment 34 Mendel used pure breeding plants as his parental strains. Which of the following are characteristics of these plants? they are homozygous they always display the recessive trait (and thus are useful in test crosses) the F1 generation produced from the cross of a male dominant and a female recessive (for the same character) I consist of only homozygotes the F2 generation produced from the cross of F1 offspring of pure breeding parents (one dominant and one ssive) will all display the dominant trait self-pollinate assort 35 Mendel obtained his P generation by allowing plants to te cancer may originate in many regions of the body, many patients die from cancerous growth in the lungs, lymph glands, or liver. This is most readily explained as spreading of cancer by angiogenesis. metastasis occurring more commonly in organs that have a fiter effect proteinase enzymes making cancer partioularly damaging to these tissues . growth anywhere but in these organs is called benign In which stage (or phase) can chromosomes first be seen with the light micr 37 ) Interphase Anaphase Prophase )Cytokinesis 38-In which phase ofmeiosis does the nuclear membrane reform? ) Prophase ) Telophase which phase of meiosis does the nuclear membrane disappear? ) Cytokinesis 39 Prophase ) Telophase litorali’s and Thermus aquaticus are thermophilic bacteria that are: Jused as cloning vectors sources of heat stable DNA polymerases genetically engineered bacteria principal sources of restriction endonucleases ich is NOT a major function of the genetic material? A. store information C.replicate itself catalyze chemical reactions un
