What size fragments you would expect from an ecotl/xhol double digest of the plasmid below? ecay 1.25 kbl bambi 2.5 kb bm 1.25 kb ecori 2 kb a) 1.25 kb, 2 kb. 2.5 kb. 3 kb b) 1.25 kb, 2.5 kb. 3 kb, 3.25 kb c) 2.5 kb. 3 kb. 3.25 kb d) 2 kb, 3.75 kb, 4.25 kb e) 2 kb. 8 kb 145. to study the maximum amount of genome diversity in humans, which of the following provides the most information? a) karyotyping d) sequencing of one or more specific genes b) snp variation e) ortholog comparisons c) dna fingerprinting 146.a researcher measures the quantity of cdna that corresponds to the exons of a particular gene in mice using rna seq. they find that rna for this gene isolated from the brain contains 4 exons, while rna from the liver heart and skin contains 5 exons. what phenomenon likely explains this result? a) cells of the brain splice this mrna differently than other cells in the mouse b) the mrna in the brain is a pseudogene cl the brain cell chromosome lacks the exon that is present in the other cells of the mouse d) the skin, liver and heart cells differentiate before the brain and so have different exons e) there is a brain-specific allele compared to the other cells in the mouse 147. polymerase chain reaction (pcr) is used to detect which type of genetic variation? a) aneuploidy d) triplet repeat expansions b) translocations e) inversions clmonosomy
