Answer:
1. The substition that least affect on the enzymatic activity would be (arginine) because lysine is( positively) charged at physiological ph.
The substitution that have effect most on the enzymatic activity would be (Glu) because it is (negatively) charged at physiological pH.
Explanation:
Fill In The Blank. In three separate site-directed mutagenesis experiments, scientists altered a Lys residue in corn PEP carboxylase to an Asn, Glu, or Arg. The substitution that you would expect to have the least effect on enzymatic activity would be ARGININE because it, like Lys, is POSITIVELY charged at physiological pH. The substitution that you would expect to have the most effect on enzymatic activity would be GLU because it is NEGATIVELY charged at physiological pH. (Use structure tables if you need to.)
1. A unicellular organism with no nucleus is a <span>Prokaryotes. </span>
2. The type of infection in which a virus does not immediately start replicating itself, but inserts a piece of DNA into the host cell’s genome which becomes activated at a later date is called a Lysogenic infection
3. A spiral or corkscrew-shaped prokaryote is called Spirillum
4. The thick internal wall that can enclose a prokaryote’s DNA and some cytoplasm when conditions are unfavorable is called a <span>Endospore</span>
