Textbook Question
Chapter 17, Problem 11TYU
scientific inquiry Knowing that the genetic code is almost universal, a scientist uses molecular biological methods to insert the human β-globin gene (shown in Figure 17.12) into bacterial cells, hoping the cells will express it and synthesize functional β-globin protein. Instead, the protein produced is nonfunctional and is found to contain many fewer amino acids than does β-globin made by a eukaryotic cell. Explain why.

Hi, Can someone solve this question, what are the steps of translation in order based on when they occur?
It would be nice if some solved it
. The genetic code is thought to have evolved to maximize genetic stability
by minimizing the effect on protein function of most substitution muta-
tions (single-base changes). We will use the six arginine codons to test this
idea. Consider all of the substitutions that could affect all of the six arginine
codons.
(a) How many total mutations are possible?
(b) How many of these mutations are "silent," in the sense that the mutant
codon is changed to another Arg codon?
(c) How many of these mutations are conservative, in the sense that an Arg
codon is changed to a functionally similar Lys codon?
