Question: The change of a single base in the DNA sequence
The change of a single base in the DNA sequence for normal hemoglobin can encode for the abnormal hemo¬globin, giving rise to sickle cell anemia. Which base in the codon for glu in DNA is replaced to give the codon(s) for val?
Relevant QuestionsThe average molar mass of one base pair of nucleotides in DNA is approximately 600 g/mol. The spacing between successive base pairs is about 0.34 nm, and a complete turn in the helical structure of DNA occurs about every 3.4 ...A compound containing only carbon and hydrogen is 85.63% C by mass. Reaction of this compound with H2O produces a secondary alcohol as the major product and a primary alcohol as the minor product. If the molar mass of the ...Consider the following five compounds. a. CH3CH2CH2CH2CH3 b. c. CH3CH2CH2CH2CH2CH3 d. e. The boiling points of these five compounds are 9.5°C, 36°C, 69°C, 76°C, and 117°C. Which compound boils at 36°C? Explain. In glycine, the carboxylic acid group has Ka = 4.3 X 10-3 and the amino group has Kb = 6.0 X 10-5. Use these equilibrium constant values to calculate the equilibrium constants for the following. a. b. c. Consider the titration of 50.0 mL of 1.0 M glycine hy-drochloride [(H3NCH2COOH)CI], with 1.0 M NaOH. For +H3NCH2COOH, Ka for the carboxylic acid group is 4.3 X 10-3 and Kb, for the amino group is 6.0 X 10-5. a. Calculate the ...
