What is the basic structure of an amino acid? What do they look like? -
VERIFIED ANSWER✅ amino group (NH2 or NH3), carboxyl group (COO or
COOH), alpha carbon (C), and variable group
Hemophilia Pedigree - Father has hemophilia, mother does not. What is
the outcome for their kids? - VERIFIED ANSWER✅ His daughters would
be carriers. This is x-link recessive.
How do you identify the 3 different types of side chains: non-
polar/hydrophobic, polar, and charged? - VERIFIED ANSWER✅ Non-
polar/hydrophobic - end with CH or "can't have" water. Polar - end with
OH, SH, or NH. Charged - end with a charge
what kinds of bonds do each of the 3 different types of side chains make?
- VERIFIED ANSWER✅ ionic, hydrophobic/non-polar, charged
,Which level of protein structure is disrupted through the hydrolysis of
peptide bonds - VERIFIED ANSWER✅ primary - The primary structure of
a protein is the sequence of amino acids held together by peptide bonds.
Peptide bonds are formed by dehydration and disrupted hydrolysis
A mutation in the beta-hemoglobin gene, which results in the replacement
of the amino acid glutamate in position 6 with the amino acid valine, leads
to the development of sickle cell anemia. The structures of glutamate and
valine are shown below.
If the beta hemoglobin gene in a patient with sickle-cell anemia were to be
edited so that the valine in position 6 was replaced with a different amino
acid, which replacement for valine would be expected to have the best
clinical outcome, in theory, for the patient? (Assume the valine can
potentially be replaced with an amino acid other than glutamate.) -
VERIFIED ANSWER✅ Valine is what is causing sickle cell anemia. The
best answer is to be to pick the structure that looks most like the
Glutamate r group
Secondary, tertiary, and quaternary levels of protein structure can all be
impacted by exposing a protein to which treatment? - VERIFIED
ANSWER✅ Placement of the protein in a solution with a low pH
,An increase in beta-pleated sheet structure in some brain proteins can
lead to an increase in amyloid deposit formation, characteristic of some
neurodegenerative diseases. What is the primary biochemical process
that follows the increase in beta-pleated sheet structure that leads to the
development of the amyloid deposits? - VERIFIED ANSWER✅ Aggregation
of the proteins in the brain
Which level of protein structure is determined by the sequence of amino
acids? - VERIFIED ANSWER✅ Primary structure - simply the sequence
of amino acids held together by peptide bonds
Autosomal:
Dominant: - VERIFIED ANSWER✅ Autosomal: males and females equally
affected.
Dominant: non-carrier parents
What are the 4 levels of protein structure? - VERIFIED ANSWER✅
Primary - linear structure, Secondary - Folded into helix or pleated sheet
caused by hydrogen bonding, tertiary - 3D structure caused by side chain
interactions, quaternary - 1+ amino acid chains combine = multiple
subunits MUST have 1+ subunit
, What enviormental change breaks each type of bond? - VERIFIED
ANSWER✅ hydrophobic - temperature change, ionic - salt or decreased
pH, hydrogen - temperature, change in pH, disulfide - reducing agents
what type of amino acid side chain leads to protein aggregration? -
VERIFIED ANSWER✅ hydrophobic bonds
how do environmental changes affect protein folding? - VERIFIED
ANSWER✅ Extreme temp can cause hydrogen bonds to break apart =
malformation of protein folding
how do mutations affect protein structure? - VERIFIED ANSWER✅ Can
cause structure to change. Protein loses form = loses function. May form
a different protein.
polymerase chain reaction (PCR) - VERIFIED ANSWER✅ The process of
copying DNA in the lab. Uses Template DNA, Nucleotides (dNTPS), DNA
Polymerase, and DNA primers.
