1. The following two pentose sugars (x) and (Y) are found in Nucleic acids. Which one is found in RNA and which one is found in DNA? 5 CH2OH OH OH 3 2 2 OH A. X is found in RNA and Y is found in DNA B. X is found in DNA and Y is found in RNA C. Both X and Y are found in DNA only D. Both X and Y are found in RNA only E. Both X and Y are found in DNA and RNA 2. Which of the following of two kinds of triglycerides X or Y is likely to be a solid and which one a liquid at room temperature?Explanation / Answer
1. B
DNA is deoxy ribose so at 2' position in Ribose have H
RNA has ribose so at 2' position in Ribose have OH group
2. B
X have saturated Fatty acids so at room temperature it require high melting temperature for fluidity. So it becomes solid
Y have unsaturated Fatty acids that why the bends is forming. it require low melting temperature for fluidity. So it becomes liquid range.
3. D Hydrogenation reaction
4. E Lipids are not macro molecules So option A is correct.
All polymers and triglycerides are formed from dehydration reaction.
5. A
