What is the basic structure of an amino acid? What do they look like? - amino group (NH2 or NH3), carboxyl group (COO or COOH), alpha carbon (C), and variable group How do you identify the 3 different types of side chains: non-polar/hydrophobic, polar, and charged? - 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? - ionic, hydrophobic/non-polar...

Which level of protein structure is disrupted through the hydrolysis of peptide bonds? 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...

Complementary DNA and/or RNA molecules pair with each other by hydrogen bonding during replication, transcription, or translation. Which of the following pairs of molecules are complementary? (Select all that apply) - tRNA and mRNA mRNA and template DNA During DNA replication the parent strands ______ and DNA polymerase______. - separate, creates the new DNA strands The following sequence is one strand of the DNA that makes up the SNCA gene that codes for alpha-synuclein, a protein found ...

The polysaccharide cellulose is composed of sugar monomers linked through beta linkages, with their CH2OH groups in opposite direction relative to the neighboring monomer. - True Nutrient that can not be broken down to a substance that can participate in the production of ATP via aerobic cellular metabolism - Vitamin E Glycolysis produces 2 ATP molecules, through what process are these ATP molecules made? - Substrate level phosphorylation What product of beta oxidation is able to enter the...

Hb (hemoglobin) binds to CO (carbon monoxide) with a higher affinity than oxygen and stabilizes the R (relaxed) state - True When hemoglobin changes from the T to the R, it has a high affinity for oxygen - True When hemoglobin changes from the R to T, it has a low affinity for oxygen - True Cooperatively refers to - structural changes that increases the affinity for oxygen in hemoglobin When the oxygen concentration is high, the heme shape is planar. When the oxygen concentration is low, ...

Which mRNA sequence results in a polypeptide that contains three amino acids? - 5' - CUU GAU ACU UAG - 3' Which RNA sequence would end in the following polypeptide? Phe-Thr-Val-Stop - 5' - UUC ACA GUA UAA - 3' What is the complementary sequence for the following DNA sequence? 5' - GCC ATC TCG AAT - 3' - 5' - ATT CGA GAT GGC - 3' Assuming 100% reaction efficiency, how many DNA copies are created after the completion of four complete PCR cycles? - 16 What is the function of DNA pol...

Deedra's dad has Alzheimer's Disease (AD) which is caused by a change in protein structure - True Alzheimer's disease is caused by aggregation of the Amyloid beta peptide and tangle formation by the tau protein. What kinds of amino acids are likely to drive the formation of these protein aggregates? - hydrophobic After learning about Alzheimer's disease and one of the drugs used in its treatment, what other drug design strategies could you use to offer treatment for AD? - 1. Drugs that...

DNA replication is semiconservative, which allows each of the 2 strands to serve as a template for the new strands - true Recall that the DNA polymerase must bind a double-stranded polymer before it can start making its own DNA polymer. What helps the DNA polymerase to overcome this problem in DNA replication? - RNA primers Several components of cigarette smoke, including benzopyrene, insert themselves into the DNA and lead to several types of mutations such as frameshift mutations, includ...

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 strands of the target DNA. (Note: In DNA rep...
