THE PROCESS OF SCIENCE 10. Some scientists once joked that when the DNA sequence of the human sn was complete, we can all go home" because there would be nothin eft for genetic researchers to discover. Why haven't they all'gone home 11. Interpreting Data When comparing genomes from different speaes biologists often calculate the genome density, the number of genes pe number of nucdeotides culate the gene density of each species by dividing the number of genes by the size of the genome (usually expressed in Mb, which is mega base pairs, or 1 million base pairs). Using a spreadsheet, calculate the gene density for every species in the table. (Don't forget that 1 billion 1,000 million; for example, humans have 3,000 Mb.) How does the gene density of bacteria compare to humans? Humans and roundwoms have nearly the same number of genes, but how do the gene densibes of these two species compare? Can you identify any genera between gene density and the size or complexity of an organism in the genome. Refer to Table 12.1. You can ca 12. Listed below are 4 of the 13 genome sites used to create a standard DNA profile. Each site consists of a number of short tandem repeats: sets of 4 nucleotides repeated in a row within the genome. For each site, the number of repeats found at that site for this individual are listed # of repeats Genetic site 0351358 DSS818 D7S820 DBS1179 Chromosome number 10 Imagine you perform a PCR procedure to create a DNA profile for this individual. Which of the following four gels correctly represents the DNA profile of this person? 240Explanation / Answer
10. because after sequencing the human genome it open a window to all mew science genomics and the bio informatics
which include a lot of area for diagnosis and research
and afterall its a joke thats why they didn't go home
11 didn't have table
12 the 'd' represent the correct one as
in agrose gel smallest size dna cover large distance so the lowermost is of 4 repeats 2nd lower id of 5 repeats middle one is of 10 repeats and upper one of 22 repeats
as repeats make dna segment large so 22 repeats dna is largest and travel short distance
and 4 repeat is smallest and cover more distance along with 5 repeats
