A bloactlve hexapeptide was cleaved by trypsln from a larger proteln. The peptlde wassequenced by treatment with varlOus reagents and enzymes. The results are as follows:a) Treatment with cyan0gen bromlde gave a tetrapeptlde of compositlon asp, trp, cysand met.b) Treatment with chymotrypsln gave a tripeptlde of compositlon asp, trp and cys, adipeptlde wlth the same C-term and an amlno acld.c) Treatment with streptococcal protease gave a dipeptlde and a tetrapeptlde.The composltion of the peptlde Is lys, trp, asp, cys and met1. What Is the sequence of the hexapeptlde?2. What is the pl of thls peptlde?

The pathway for arginine biosynthesis in Neurospora crassa involves several enzymes that produce a series of intermediates as shown. O O O O ornithine citrulline ARG-E arginosuccinate arginine N-acetylornithine arginine You did a cross between ARG-E ARG-H* and ARG-E* ARG-H¯¯ Neurospora strains and identified an Arg- strain from an NPD tetrad. (Assume that Neurospora forms tetrads in the same way yeast do.) Which compound would rescue growth of this Arg- spore? N-aceltylornithine ARG-F ornithine citrulline ARG-G ARG-H → argininosuccinate
A research group collaborating with the hospital extracted DNA from the peripheral blood leucocytes of the patient V.1, her sister V.2, her mother IV.1 and her father IV.2 with consent and ethical approval for experimental work involving human tissues. These specimens were used for sequencing studies to screen for causative variants in amyloid precursor protein (APP), presenilin-1 (PSEN1) and presenlin-2 (PSEN-2) genes.
