Answer #1

The answer for this question are option

1. Histidine to lysine

2. serine to threonine

6. aspartate to glycine

Bacause histidine and lysine are basic in nature, serine and threonine are hydroxyl or sulphur containing where as aspartate and glycine are acidic in nature. Apart from this these pairs are the examples of conservative amino acid replacement in which one animo acid is changed into another which have similar biochemical properties like charge, hydrophobicity, nature and size etc

but the reaining options does not comes under conservative amino acid replacement therefore they will alter the properties.

    On your internship, you visit the Mass Spectrometry Lab. Mass spectrometry can identify short peptide fragments based on their molecular weights. Your fellow intern Jerry has neglected to label his tubes of amyloid beta peptide 42 after digesting them with some proteases that we learned about in Module 6: pepsin, trypsin, and chymotrypsin. Help him figure out what protease is in each tube. Jerry’s supervisor has the fragments listed in the same order as the original peptide primary sequence, which...
