Is genetic engineering a pure scientific process or it is indeed on act of humans playing like God? Explain.

reaction LU Lake Piu Figure 1 (at right): Tertiary structure of the digestive enzyme trypsin from Streptomyces griseus. The substrate binds the active site, indicated with darker color. Critical Thinking Questions: 6. Circle the active site of the enzyme in Figure 1. 7. Circle the side chains in each amino acid below. To which class (hydrophobic, polar, charged) does each belong? (You should be able to do this without looking at a table). O о TO-C-CH2-CH-C-O NH3 Charged hydrophobic CH3CH-C-O¯ NH3 O Charmed HO-CH2-CH-C-O H3N CH2CH2CH2CH2CH-C-O- Polar NH3 8. Suppose that aspartate (the first amino acid shown in CTQ 7) is part of a substrate. Hypothesize which of the other three amino acid side chains might be present in the active site of an enzyme in order to interact with aspartate. Work with your team to explain.

Please answer the first question (number 7)

Part C and D

8. Two substitution mutations are shown below; each changes an mRNA codon for an enzyme: UUA changes to AUA GAU changes to GUU One substitution has little effect on the biological activity of the enzyme, while the other is highly damaging. Predict which mutation will cause more damage, and justify your answer.

4 and 5 please, I’m stuck on these
