Multiple Choice Question
Read the assertion and reason carefully.
कथन और कारण को ध्यान से पढ़ें।
Assertion (A): During agarose gel electrophoresis, DNA fragments migrate towards the positive electrode (anode).Reason (R): The sugar-phosphate backbone of DNA molecules imparts a net negative charge at neutral and alkaline pH.कथन (A): एगारोज़ जेल इलेक्ट्रोफोरेसिस के दौरान, डीएनए के टुकड़े सकारात्मक इलेक्ट्रोड (एनोड) की ओर पलायन करते हैं।कारण (R): डीएनए अणुओं की चीनी-फॉस्फेट (sugar-phosphate) बैकबोन तटस्थ और क्षारीय pH पर शुद्ध नकारात्मक चार्ज प्रदान करती है।
Explanation:
DNA is negatively charged due to its phosphate groups, causing it to migrate towards the positive pole (anode) under the influence of an electric field.
डीएनए अपने फॉस्फेट समूहों के कारण नकारात्मक रूप से चार्ज होता है, जिससे यह विद्युत क्षेत्र के प्रभाव में सकारात्मक ध्रुव (एनोड) की ओर पलायन करता है।
