What are the monomers of proteins what ultimately

Question

1. What are the monomers of proteins?
2. What ultimately determines protein shape (hint: think levels of protein structure)?
3. Define mutation.
4. If CTT is the normal sequence of nucleotides on DNA, what is the resulting mRNA codon? What amino acid does this code for
5. When a point mutation changes the DNA sequence to CAT, how is the mRNA codon affected? What amino acid does this code for? What is the implication of this change in sequence (hint: see question 2)?
6. When people have sickle cell anemia they cannot efficiently transport oxygen. What are the implications at the cellular level (hint: why do cells need oxygen)? Describe how this deprivation of oxygen might make these patients feel.
7. Why doesn't a blood transfusion cure this disease?
