Each somatic cell contains a copy of an individual’s entire genome. The entire genome is by no means used in each somatic cell, but all of the DNA is present. The only cells that differ genetically would be germ line cells: because they are gametes, they only have 1 copy of each chromosome in any combination. 27. 1) Count Differences between each sequence 2) Map them on a grid and isolate lowest number and link those two. In this case, it is 1,3. Connect those. 3) Find lowest number Again and repeat. 4) Map the Endpoints logically by which are closer and thus more closely related.

Unformatted text preview: 28. In prokaryotes, first the DNA is transcribed into a complementary sequence of mRNA. RNA polymerase locates the promoter for the gene and its -subunit binds to it. The polymerase then breaks the hydrogen bonds between base pairs, creating a transcription bubble where the remaining 4 RNA Polymerase subunits travel along the template strand in the 3 5 direction, adding rNTPs and creating the mRNA molecule in 2 3 4 5 1 6 2 4 8 2 8 8 3 3 5 8 4 9 2 4 5 (1,3) 7 4.5 8 2 8 3 4 9 (2,5) 4 (1,3) 7.5 4.5 (2, 5) 8.5 (1 to 2), 6 (2 to 3), 8 (3 to 4), 5 (4 to 5), 9 (1 to 3), 2 (2 to 4), 8 (3 to 5), 8 (1 to 5), 8 (1 to 4), 4 (2 to 5), 3 1 3 1 3 2 5 4...
