What would happen if Chelex beads get transferred into the PRC tube? 1pt (c.)You want to amplify by PCR the entire DNA fragment (50 bp total) shown below. You have to design both forward and reverse primers that are 10 nucleotides long.5’-ACCGTTAAGG AACCGGTTTG ACTGAGATCA GTCAACCGTA GGCCTGCATC-3’3’-TGGCAATTCC TTGGCCAAAC TGACTCTAGT CAGTTGGCAT CCGGACGTAG-5’(c.i.)In the table below, write down the primer sequences with the correct directionality (5’→3’). 1 pt(c.ii.)Use an online Tm calculator (cite source) to estimate the melting temperaturesof the forward and reverse primers for this fragment. Provide the parameters listed in the table below. D1S80 is done below (). 1pt(c.iii.)Based on the typical suggestion of 1 min elongation per 1kb amplicon, estimatea minimum elongation time for the 50 bp length of this fragment? Compare this to the elongation time used in the Touchdown program. 1ptExercise 5 Page 5of 15
