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 polymerase in the process of PCR? It recognizes the primers and uses the available dNTPs to replicate the template DNA sequence. What are possible blood types of the parents of a patient with blood type AB? A and B − Amino Acid Number Tyr Gly Thr Pro − Amino Acid Sequence TAC GGG ACA CCA − DNA Sequence What is the amino acid in positio...

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 cell...

Amino Group Consists of hydrogen and nitrogen atoms (NH3+) Carboxyl Group Consists of carbons and oxygens (COO-) R Group The variable group within an Amino Acid Amino Acid Backbone Consists of the Amino Group (NH3+) the Carboxyl Group (COO-) and the Alpha Carbon that bonds to a Hydrogen Monomer A small chemical unit that makes up a polymer Polymer A long molecule consisting of many similar or identical monomers linked together. Polypeptide A polymer (chain) of many amino acids linked toge...

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, char...
