Homework Answers
One hydrophobic amino acid is replaced with another hydrophobic amino acid.
AUU codes for Isoeucine and CUU for leucine both of which are hydrophobic.

Match each mutation with its appropriate description. A mutation that changes a codon that specifies an amino acid to a stop codon, resulting in premature termination of polypeptide synthesis. Silent mutation Frameshift mutation A mutation that results in a change in a codon such that a different amino acid is specified es Missense mutation A mutation that changes one codon to a different codon that specifies the same amino acid, such that there is no change in the resulting polypeptide....
The gene encoding protein Bog in E. coli has been changed by a point mutation in...
The gene encoding protein Bog in E. coli has been changed by a point mutation in its open reading frame. Originally the gene encoded a 108 amino acid long functioning protein whose amino acid composition favored nonpolar and negatively charged amino acids. After the mutation it encodes a 110 amino acid long non-functioning protein that is now rich in polar uncharged amino acids and positively charged amino acids. Which mutation scenario best explains this observation. A) A frame-shift caused by...

A substitution mutation is one in which one nucleotide base is changed to another
2. A substitution mutation is one in which one nucleotide base is changed to another Suggest ONE substitution A G mutation in the DNA that would cause the first amino acid in the "# of Eyes" gene to change from alanine (Ala) to valine (Val). In the table below, write the original.3. There is a substitution mutation in the gene for Fangs in which the first DNA base changes from guanine to thymine. The mutation results in a genetic disorder...

4. (4 pts) in premature termination of translation. These mutations are not as rare as you might think. For example, there are 8 different sense codons that can be changed to the stop codon UAG by a single point mutation (base change). Nonsense mutations are mutations that introduce a STOP codon in place of a sense codon, and result Using the codon table in the textbook, list these 8 sense codons (and their corresponding amino acid) Consider the following introduction...
