- Suppose you are characterizing the DNA of a diploidplant species that had never been analyzed previously.You purify all the DNA that can be isolated from a seedling, and subject this DNA to high-throughput sequencinginvolving millions of reads of random DNA fragments.a. If you obtained on average 100 reads of a givensingle-copy nuclear DNA sequence, about howmany reads would you obtain for mtDNA? ForcpDNA? (Assume each mitochondrion has10 genome copies and that each choloroplast has20 genome copies. Assume also that the averagecell of this plant species has 1000 mitochondriaand 50 chloroplasts.)b. Beyond the number of reads, what other criteriawould allow you to conclude whether a particularread was of nuclear DNA, mtDNA, or cpDNA?arrow_forward. Genomes A, B, and C all have basic chromosomenumbers (x) of nine. These genomes were derivedoriginally from plant species that had diverged from each other sufficiently far back in the evolutionarypast that the chromosomes from one genome can nolonger pair with the chromosomes from any other genome. For plants with the following kinds of euploidchromosome complements, (i) state the number ofchromosomes in the organism; (ii) provide terms thatdescribe the individual’s genetic makeup as accurately as possible; (iii) state whether or not it is likelythat this plant will be fertile, and if so, give the number of chromosomes (n) in the gametes.a.
