WGU Biochemistry OA (Latest 2022/2023) Verified Answers Bohr Effect chart (low pH) C- High CO2 H- High H+ A- Acidic R-Release of O2(rt. Shift) T- tense state (in tissues) Primary structure Sequence of amino acids that make up a protein Secondary Structure Sequence of amino acids fold. Tertiary Structure -more folding in a 3D shape. -R groups (side chains) Quaternary Structure Protein has more than 1 polypeptide chain. Chemical reaction -absorb and release en...

Which level of protein structure is disrupted through the hydrolysis of peptide bonds? Quaternary Tertiary Primary Secondary - 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 reactions and disrupted by 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 develop...

Large pressure gradient between left ventricle and aorta during systole - Answer- aortic stenosis (calcification) Hyperacute transplant rejection is what type of hypersensitivty rxn - Answer- type 2 - pre existant recipient antibodies react to donor antigen acute transplant rejection is what type of hypersensitivity rxn - Answer- type 4- T cell mediated OR humoral: similar to hyperacute except antibodies form after transplant which type of transplant rejection is both type 2 and type...

WGU Biochemistry Final Review 1. The polymerase chain reaction is a tool used to study protein structure. True False False Feedback PCR is a tool used to amplify a specific segment of DNA. What color is the primer in the following diagram? Red Purple Blue Red Feedback Recall from the section on DNA replication that DNA polymerase needs a primer to begin DNA synthesis. This requirement means the primers will direct the DNA polymerase to only synthesize complementary stran...

cystic fibrosis - ANSWER-effects pancreas, increased mucus Klinefelter syndrome - ANSWER-A chromosomal disorder in which males have an extra X chromosome Turner Syndrome - ANSWER-A chromosomal disorder in females in which either an X chromosome is missing, making the person XO instead of XX, or part of one X chromosome is deleted. Alpha Thalassemia - ANSWER-Severe anemia, do not give ferrous sulfate B and T cells - ANSWER-Mature in bone marrow, the go to thymus/spleen/liver Lichen...

hemoglobinopathy - ️️genetic mutation in the genes that affect hemoglobin synthesis, leading to a diseased hemoglobin molecule qualitative hemoglobinopathy - ️️gene mutation leads to altered amino acid sequence in the hemoglobin molecule, affecting the structure and function of the hemoglobin -amino acids with different charges and biochemical characteristics leads to dysfunctional and unstable hemolgobin -e.g. sickle cell disease, hemoglobin C disease, etc. quantitative hemoglobi...

Quaternary Tertiary Primary Secondary - Primary The primary structure of a protein is the sequence of amino acids held together by peptide bonds. Peptide bonds are formed by dehydration reactions and disrupted by 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 ce...

Gametes Sex cells 2. Karyotype A display of the chromosome pairs of a cell arranged by size and shape. 3. Process for karyotyping Typically done by isolating white blood cells from a person, staining them, and taking pictures under a microscope. The picture is then cut to organize chromosomes, which are numbered by size 4. Cytogeneticist a scientist who studies chromosomes under the microscope 5. BRCA1 gene Breast cancer type 1 susceptibility gene. A human tumor suppressor gene that is...
