MAKE CONNECTIONS Speculate about whether thesame enzyme could methylate both a histone and a DNAbase. (See Concept 5.4.)
Please help
a. How many chromosomes and/or sister chromatids do Figure A and B show?
b. What is the name of the process that took place to get from structure A to structure B?
MAKE CONNECTIONS Look at Figure 12.7 and imagine the twodaughter cells undergoing another round of mitosis, yielding four cells.Compare the number of chromosomes in each of those four cells, aftermitosis, with the number in each cell in Figure 13.8, after meiosis. Whatis it about the process of meiosis that accounts for this difference, eventhough meiosis also includes two cell divisions?

- Instructions: have a look at “Figure 2.pdf”. This shows a diagram mapping the Arabidopsis Rab proteins onto regions of the Arabidopsis genome that appear to have been duplicated during the evolution of the genome. The vertical bars represent Arabidopsis chromosome 1-5, the broad shaded areas are regions that have high degrees of similarity between two chromosomes or regions of the same chromosome (and are therefore likely to have been duplication events of the chromosomes during evolution). The arrows show the direction (5’ to 3’) that the genes face on the chromosome. Compare the suggested evolutionary relationships of the green Rab proteins in “Figure 1.pdf” to their genomic location in “Figure 2.pdf”. Question: Briefly speculate about the implications of the results shown in “Figure 2.pdf” by thinking about how the diversity of Rab proteins might have arisen in this species.arrow_forwardInstructions: have a look at “Figure 2.pdf”.
