Answer:
none of these codons
Explanation:
In order for mutation to occur to form methionine codon from an isoleucine codon, position 3 must be changed to a G, giving AUG. A secind mutation would then be required at a second site in the AUG codon. since the isoleucine codons, AUA, AUC and AUU does not have a G at position 3, a true reversion can't occur without mutating the position 3 again.
Answer:
People, not machines, perform fingerprinting. They do search for a particular amount of matches before taking into account a whole match.
Explanation:
Answer: As scientists started improving on the microscopes, the more they got to observe the cells in depth. Compound light microscope uses visible light to produce a magnified image and doesn't allow it to scatter.
Answer:
Similarly, enzymes can only function in a certain pH range (acidic/alkaline). Their preference depends on where they are found in the body. For instance, enzymes in the intestines work best at 7.5 pH, whereas enzymes in the stomach work best at pH 2 because the stomach is much more acidic.
