(i) When constructing cDNA libraries it is very important to copy the whole of an mRNA into cDNA. One way to try and ensure that the 5′ end of a mRNA is represented in a cDNA copy is to use “cap-trapper” technology. Explain in your own words and with a […]

Accidental wastewater spills from unconventional oil production in North Dakota have caused widespread water and soil contamination, a new study finds. Researchers found high levels of contaminants and salt in surface waters polluted by the brine-laden wastewater, which primarily comes from fracked wells. Soil at spill sites was contaminated with […]

In accordance with the Theory of Evolution, Natural Selection is mechanism through which the evolution happens. Advantageous traits survive the longest and leave the most offspring, a process termed as Natural Selection. Select an animal species. Your goal is to explain the way where an evolutionary change might takes place […]

Q. A DNA-like molecule is isolated from the frozen remains of alien life-forms found beneath the Martian North polar ice cap. The molecule is a double stranded polymer whose monomeric subunits are collected of glycerol, phosphate and nitrogenous bases, of which four kinds were found. The bases in this “glyceronucleic […]
