Assuming 100% reaction efficiency, how many DNA copies are created after the completion of four complete PCR cycles? - ANS 16 What is the function of DNA polymerase in the process of PCR? - ANS 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? - ANS A and B − Amino Acid Number Tyr Gly Thr Pro − Amino Acid Sequence TAC GGG ACA CCA −...

Which level of protein structure is disrupted through the hydrolysis of peptide bonds? Quaternary Tertiary Primary Secondary - ANS 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 de...

• DNA = phosphate + deoxyribose sugar + A/T/C/G o Contains two strands. The strands are antiparallel (opposite each other). o 5’ → 3’ 3’ ← 5’ • RNA = phosphate + ribose sugar + A/U/C/G o Single strand, can fold back onto itself and form pairs between itself (stem‐loop). • Each nucleic acid is made up of polymers (many monomers) that are called nucleotides. o Nucleotides contain one or more phosphates, a five‐carbon sugar, and a nitrogen base. o Nucleotides are alway...
