13.3 A highly sensitive instrument (which has not yet been invented) detects that one of the carbon atoms exhaled in Darwin's last breath when he died now resides in his blood where it is part of a hemoglobin molecule. Hint how this carbon atom could get from Darwin to you and mention some of the molecules they might have had on that route.

(a) Explain why the term " junk dna" may not be such an accurate description? (b) provide 1 similarity and 1 difference between the structure of individual genes of eukaroyotes and prokayotes

mtDNA depletion syndrome 13 is a rare genetic disorder, in which individuals have fewer mitochondria in the muscles than normal because the organelles are degraded by lysosomes. Would this disorder impact the muscles' ability to perform the Cori Cycle? O Yes, it would interfere with lactic acid fermentation. O Yes, it would interfere with aerobic gluconeogenesis. O Yes, it would interfere with anaerobic glycolysis. O No, it would not impact the Cori Cycle.

Suppose you had a method of cutting DNA at specific sequences of nucleotides. how many nucleotides long (on average) would such a sequence have to be in order to make just one cut in a bacterial genome of 3 × 106 nucleotide pairs?

Please consider Figures, 10.28, and Table 10.2 (attached), which contain data that were collected by Delph and Lively, are redepicted from their paper that was published in 1989, and for which information is provided on pp. 391-383 in the textbook (pp. 385-388 in the 4TH edition textbook); assess the lowercase-Roman-numeral-labelled statements that appear immediately below; and click the uppercase-letter-labelled response that is presented below and conveys the most accurate information. i. Germinated pollen grains in Fuchsia excorticata grow tubes that extend from the stigma, through the style, to the ovary, where one sperm unites with one egg; this requires approximately 3 days. ii. Before a Fuchsia excorticata flower can detach from the tree, an abscission zone must be developed; this typically requires 1.5 days. iii. Colour change in Fuchsia excorticata probably evolved as an adaptation to the physiologically constraining 4.5 days that are required for fertilisation and abscission…
