TEST BANK FOR GENETICS FROM GENES TO GENOMES 6TH EDITION BY HARTWELL – COMPLETE ALL CHAPTERS. Which statement supports the theory that all organisms are related? - The genetic code is almost universal. 6) New genes are thought to arise by which mechanism? - Gene duplication followed by divergence due to mutation. 7) What is the most likely way a mutation in one gene can convert one body part to another? - The mutated gene encodes a protein that affects the expression of many other genes. 8) A recent technical advancement that has accelerated the study of genomes is the abilityto - sequence large complex genomes rapidly and inexpensively. 9) What is the difference between genetic dissection and genome sequencing? - Genetic dissection reveals information about one gene at a time and genomesequencing reveals information about all the genes in a genome at once. 10) Currently, what information can be obtained from sequencing an individual's genome? - Information about gene variants that predispose a person to a disease, such ascI ancer. 11) Which is not a potential problem of allowing the genomic sequences of individuals tobecome widely available? - Advances leading to healthier lives for some people. 12) One strand of DNA has the sequence 5′ GGTCTA 3′. What is the sequence of the otherstrand? - 5′ TAGACC 3′ 13) Which statement is true about the structure of DNA? - The two strands of a DNA molecule are held together by base pairing. 14) The size of the mouse (M. musculus) genome is 2700 megabases (Mb) and it contains about 25,000 genes arranged on 40 chromosomes. If the genes are evenly distributed on chromosomes in the mouse, what is the average number of genes per chromosome? - 625 15) Which statement about the structure of proteins is false? - Most proteins consist of two amino acid polymers attached together by hydrogen
