Is change in the order of DNA bases that code for a respiratory protein will most likely cause?
a change in the sequence of amino acids determined by a gene
What would most likely happen if there is a change in the base sequence of this molecule?
B. The amino acid sequence may be altered during protein synthesis.
What would a single change in the sequence of nitrogenous bases in a DNA molecule most likely result in?
A mutation
When are mutations likely to occur?
A base sequence in a DNA molecule is changed
If a medical test indicates that a patient has a defective protein this condition is most likely due to a change or fault in the instructions to make the protein which is coded where?
Genes of the patient's DNA.

A medical test indicates that a patient has a defective protein. This condition is most likely due to a change in the directions coded in the?
sequence of subunits in DNA.

What is the smallest change in DNA that causes a protein to change.?
A single change in the primary sequence of bases can result in complete misfolding of proteins. The most likely serious change would be addition or deletion of a base, a substitution would be less likey to be as serious but can also render a protein inactive.
What would Translation of the DNA sequence AAGCTGGGA would result in?
This would result in a frameshift mutation. This would cause the protein, after translation, to be truncated and would most likely be non-functional. This is due to a change in the amino acid sequence and would stop the protein from forming the correct secondary and tertiary structures due to a change in the electrostatic/ hydrophobic/ h-bonding etc. parameters of the protein

B. The amino acid sequence may be altered during protein synthesis.
Do mutations always alter the encoded protein structure and function?
No. Since a mutation in the DNA may not necessarily result in a change to the encoded amino acid in the protein sequence, it is entirely possible. Further, the protein function will likely not change when an amino acid is replaced with one of similar chemical properties. Sometimes it does, sometimes it doesn't. This is the field that molecular evolutionary biologists study.
Suppose part of an amino acid sequence of a protein changed from tyrosine proline glycine alanine to tyrosine histidine glycine alanine this change was most likely caused by a point mutation called?
substitution

How can the amino acid sequence determine protein shape and function?
Amino acids have different properties according to their R group. They can be negative, positive, aromatic, etc. - which will affect where that amino acid will be found, and what functions it will perform. For example, Glutamate and Aspartate are negative amino acids, and so are most likely to be found on the surface of proteins. Whereas Leucine and Methionine are hydrophobic, so they will be found in the interior of the protein. The sequence of amino acids causes the protein to fold in a certain way to find the most energetically and functionally favourable shape.
