Suppose that branch migration occurs through gene 2. Let sequence \"b\" = GGATCGATC and \"a\" = GGTTCGATC. Note that the difference between the alleles is underlined.

Part B: What is the sequence on both strands of the two resulting chromatids? Use 5\' & 3\' to specify directionality, enter paired strands on separate lines so that the sequences align, enter \"AND\" on a line between chromatids. Example: 5\'-GGATCGATC-3\' 3\'-CCTAGCTAG-5\' AND 5\'-GGTTCGATC-3\' 3\'-CCAAGCTAG-5\'

Part C: Which strand would be used as the template for repair and how would it be identified?

Part D: How many possible results from repair exist, and how many are gene conversions?

Solution

The holliday structure in the image uploaded is not visible. I will give you a general answer, please modify according to your image.

Imagine a holliday branch is formed somewhere near G_GATCGATC and \"a\" = G_GTTCGATC, in the dashed region. The the resulting strand after branch migration is.5\' GGTTCGATC 3\'/3\' CCAAGCTAG3\' AND 5\'GGATCGATC 3\'/ 3\'CGTAGATAG5\'.

The strand without methylation ( I.e the strand newsly formed ) is used as template.
