9:54Assignment: Which Has More DNA?InstructionsQuestion: Would a kiwifruit and strawberry thatare approximately the same size also haveapproximately the same amount of DNA?Background: You have learned that DNA iscarried on chromosomes. All mammals arediploid; however, not all plants are diploid. Thecommon strawberry is octoploid (8n) and thecultivated kiwi is hexaploid (6n). Research thetotal number of chromosomes in the cells of eachof these fruits and think about how this mightcorrespond to the amount of DNA in these fruits'cell nuclei.Hypothesis: Hypothesize whether you would beable to detect a difference in DNA quantity fromsimilarly sized strawberries and kiwis. Which fruitdo you think would yield more DNA?Test your hypothesis. Perform the DNAextraction experiment.Record your observations: Because you are notquantitatively measuring DNA volume, you canrecord for each trial whether the two fruitsproduced the same or different amounts of DNAas observed by eye. If one or the other fruitproduced noticeably more DNA, record this aswell. Determine whether your observations areconsistent with several pieces of each fruit.Analyze your data: Did you notice an obviousdifference in the amount of DNA produced byeach fruit? Were your results reproducible?Draw a conclusion: Given what you know aboutthe number of chromosomes in each fruit, can 9:54 1Assignment: Which Has More DNA?correspond to the amount of DNA in these fruits'cell nuclei.Hypothesis: Hypothesize whether you would beable to detect a difference in DNA quantity fromsimilarly sized strawberries and kiwis.

Look at the chromosome combinations that each child received and list their genotype and phenotype.

The mitotic cell divisions in the early embryo ofD. melanogaster occur very rapidly (every eightminutes).a. If there were one bidirectional origin in the middleof each chromosome, how many nucleotides wouldDNA polymerase have to add per second to replicate all the DNA in the longest chromosome(66 Mb) during the eight-minute early embryoniccell cycles? (Assume that replication occurs duringthe entire cell division cycle.)

(Assume that replication occurs duringthe entire cell division cycle.)b. In fact, many origins of replication are active oneach chromosome during the early embryonic divisions and are spaced approximately 7 kb apart. Calculate the average rate (per second) with whichDNA polymerase adds complementary nucleotidesto a growing chain in the early Drosophila embryo,making the same assumption as in part (a)

Preparation Assignment- Chapter 10 11. The discovery of chromosome banding in eukaryotes has greatly improved our ability to distinguish various cytogenetic events. Particularly useful are "banding" polymorphisms because the "morphs" can be used as chromosome markers. (These morphs are forms of chromosome that are cytologically distinguishable by virtue of minor variations in band size, position, etc). Let's consider chromosome 21 in humans. Assume that one set of parents are: 21ª21 (female) x 21°21ª (male), where a, b, c and d represent "morphs" of a polymorphism for this chromosome. In each case: State the genetic term for the condition (if possible), diagram the event(s) that gave rise to the condition, and state in which individual the event(s) took place. d. 42 21ª 1º + XX Interphase [show condensed]: Diagram meiosis for chromosome 21 in Mom (left) and Dad (right) After DNA replication: After Meiosis I: Interphase [show condensed]: Gametes: After DNA replication: After Meiosis I:…
