Met-Tyr-Asn-Val-Arg-Val-Tyr-Lys-Ala-Lys-Trp-Leu-Ile-His-Thr-Pro
You wish to make a set of probes to screen a cDNA library for the sequence that encodes this protein. Your probes should be at least 18 nucleotides in length.
Q. Which amino acids in the protein should be used to construct the probes so that the least degeneracy results?

- A protein has the following amino acid sequence: Met-Tyr-Asn-Val-Arg-Val-Tyr-Lys-Ala-Lys-Trp-Leu-Ile-His-Thr-Pro You wish to make a set of probes to screen a cDNA library for the sequence that encodes this protein. Your probes should be at least 18 nucleotides in length. Q. How many different probes must be synthesized to be certain that you will find the cDNA sequence that specifies the protein?arrow_forwardWhich of the following is the correct sequence for RNA splicing: 1. U2 binds to the branch site and ATP is hydrolyzed 2. U1 binds to the GU sequence at 5’ splice 3. U5/U4/U6 trimer binds 4. U2/U5/U6 are bound to lariat and 3’ site is cleaved and exons are ligated using ATP hydrolysis. 5. U1 is release, U5 shifts from exon to intron and U6 binds at the 5’ splice site 6. U4 is released, U6/U2 catalyzes transesterification, U5 binds exon at 3’ splice site, and the5’ site is cleaved.
