A mutation in enzyme X was found to associated with a genetic disease. You have the following information. a. X is single polypeptide for MW 50,000.
b. Non-denaturing electrophoretic analysis of mutant and normal X shows that the mutant behaves as if it has one extra positive charge.
c. The N-terminal amino acid is Thr and the C-terminal amino acids is Asn.
d. Both the mutant and normal X give exactly the same number of peptides when treated with trypsin (cleaves at positively charged residues).
e. Chemical modification with His specific reagents shows that both mutant and normal X have the same number of His residues.

Of the following amino acids, Lys, lle, Asp, His is the amino acid that has changed, and is the most likely the new amino acid in the mutant.

Getting rid of my account might as well do it with some fun make sure to read all of this it is hilarious a plane was about to crash and there were 5 people on board and only 4 parachutes. the first person said: " i am roy keane, one of the best footballers in ireland. i am worth a lot of money and my fans need me so i think i should be saved." the others agreed and gave him one of the parachutes and off he went. the second person said: "i am gerry adams, a radical irish politician who can really my country and i think i should be saved." the others said: "o.k.", and gave him a parachute. the third person said: "i am george bush, president of the most powerful country in the world. everyone knows i am a really nice guy and everyone thinks i am stupid,but i'm not, so i am taking a parachute." and off he went. there were two people left, the pope and a 10 year old schoolgirl. the pope said: "child, i am old and frail and have lived my life while you are young, with everything before you. you take the parachute and i will stay with the aircraft and take my chance." "it's o.k." said the girl, "there are still two bush picked up my schoolbag."

Put the following processes of protein synthesis in the correct order: - dna strands unwind and separate - mrna copies dna according to complimentary base pairing - trna's anticodons bring amino acids to the corresponding mrna codons - amino acids bind to each other making a protein - mrna leaves the nucleus - a stop codon is reached, the newly formed protein is released to go do its job for the cell

Look at the photo of the leaf. which term best describes this leaf?
