ABSTRACT In recent years, it has become clear that a substantial fraction of transiting exoplanets have some form of aerosol present in their atmospheres. Transit spectroscopy – mostly of hot Jupiters, but also of some smaller planets – has provided evidence for this, in the form of steep downward slopes from blue to red in the optical part of the spectrum, and muted gas absorption features throughout. Retrieval studies seeking to constrain the composition of exoplanet atmospheres must therefore account for the presence of aerosols. However, clouds and hazes are complex physical phenomena, and the transit spectra that are currently available allow us to constrain only some of their properties. Therefore, representation of aerosols in retrieval models requires that they are described by only a few parameters, and this has been done in a variety of ways within the literature. Here, I investigate a range of parametrizations for exoplanet aerosol and their effects on retrievals from transmission spectra of hot Jupiters HD 189733b and HD 209458b. I find that results qualitatively agree for the cloud/haze itself regardless of the parametrization used, and indeed using multiple approaches provides a more holistic picture; the retrieved abundance of H2O is also very robust to assumptions about aerosols. I also find strong evidence that aerosol on HD 209458b covers less than half of the terminator region, whilst the picture is less clear for HD 189733b.

Calotropis procera is a common medicinal plant with various properties related with its latex which functions as a rich source of biologically active compounds. Latex is chemically diverse and the chemical and biochemical differences are considerable for different plant fluids. This plant can produce large quantity of latex. The study was performed to clone the CP1102 terminator region of gene in general expression vector PTZ57R/T. The objective was to make a variant of pJITT166 (size ~5.8kb) containing CP1102 terminator sequence to study different expression levels in future. The fragment of 341bp size was isolated. The pDNOR vector containing CP1102 terminator sequence was isolated and amplified by PCR. The forward and reverse primer specific to CP1102 terminator sequence which can amplify this sequence are designed by using bioinformatics tools.
