Concept explainers
(a)
Interpretation:
The hydrogen bonds that occurs in the G-C pair and A-T pair needs to be determined.
Concept introduction:
Hydrogen bond is a type of intermolecular force formed between hydrogen atom in a molecule attached to an electronegative atom and electronegative atoms like oxygen, nitrogen, or fluorine of another molecule.
(b)
Interpretation:
The region of DNA with higher melting point, regions high in A-T pairs or regions high in G-C pairs needs to be determined.
Concept introduction:
Hydrogen bond is a type of intermolecular force formed between hydrogen atom in a molecule attached to an electronegative atom and electronegative atoms like oxygen, nitrogen, or fluorine of another molecule.
The melting point of a substance depends on the type of intermolecular force between the molecules. Stronger the intermolecular force, higher the melting point of the substance.

He plotted that data in the graph below to determine if height was a heritable trait. A. Is height a heritable trait? If yes, what is the heritability value? (2 pts) B. If the phenotypic variation is 30, what is the variation due to additive alleles?

You will divide it into three 1.5 g portions in separate 125 mL Erlenmeyer flasks savıng some for melting point analysis. Dissolve the mixture in each flask in ~60mL of DI water by heating to boiling on a hotplate. Take the flasks off the hotplate once you have a clear solution and let them stand on the bench top for 5 mins and then allow them to cool as described below. Sample A-Let the first sample cool slowly to room temperature by letting it stand on your lab bench, with occasional stirring to promote crystallization. Sample B-Cool the second sample 1n a tap-water bath to 10-15 °C Sample C-Cool the third sample in an ice-bath to 0-2 °C Results: weight after recrystalization and melting point temp. A=0.624g,102-115° B=0.765g, 80-105° C=1.135g, 77-108 What is the percent yield of A,B, and C.arrow_forward
