Multiple Choice Question
What is the wavelength of maximum absorbance for nucleic acids (DNA and RNA) used routinely in spectrophotometric quantification?स्पेक्ट्रोफोटोमेट्रिक मात्रा निर्धारण में नियमित रूप से उपयोग किए जाने वाले न्यूक्लिक एसिड (डीएनए और आरएनए) के लिए अधिकतम अवशोषण (maximum absorbance) की तरंग दैर्ध्य क्या है?
Explanation:
Nucleic acids strongly absorb ultraviolet light with a maximum absorbance (λmax) at 260 nm due to the conjugated double bonds in their purine and pyrimidine bases.
प्यूरीन और पिरिमिडीन क्षारों में संयुग्मित (conjugated) दोहरे बंधनों के कारण न्यूक्लिक एसिड 260 nm पर अधिकतम अवशोषण (λmax) के साथ पराबैंगनी प्रकाश को दृढ़ता से अवशोषित करते हैं।
