Essay

Shown below is a list of gene classes that play a role in Drosophila development.
$\quad$$\quad$$\quad$$\quad$$\quad$ homeotic genes
$\quad$$\quad$$\quad$$\quad$$\quad$ gap genes
$\quad$$\quad$$\quad$$\quad$$\quad$ segment-polarity genes
$\quad$$\quad$$\quad$$\quad$$\quad$ maternal-effect genes
$\quad$$\quad$$\quad$$\quad$$\quad$ pair-rule genes

(i)Describe the role of each class of genes and the impact that a mutation in the class has on Drosophila development.
(ii)The different classes of genes function at different times during Drosophila development.Put the gene classes in order,from earliest to latest.

Understand the concept of spin-spin splitting and be able to predict the multiplicity and ratios of peak areas.

Apply knowledge of NMR spectroscopy to structural elucidation and identification of organic compounds.

Explain the reasons behind the absence of certain splittings in NMR spectra.

Comprehend and describe the functional group effects on NMR chemical shifts.
