रक्तहीनता के उपचार में। कैन्सर के उपचार में। कैन्सर के उपचार में घाव भरने के लिए। सरल प्रसव के लिए। की परम्परागत विधियों जैसे-खून व मूत्र जाँच से सभी रोगों को नहीं जात किया जा सकता है परन्तु आधुनिक चिकित्सा प्रणाली में पुनर्योगज DNA तकनीक, पॉलीमरेज चेन अभिक्रिया (PCR), एन्जाइम सहलग्न प्रतिरक्षा शोषक आमापन (enzyme linked immunosorbant assay, ELISA) आदि कुछ ऐसी तकनीकें हैं जिनके द्वारा रोग की प्रारम्भिक पहचान की जा सकती है। 5 रोग का प्रारम्भिक स्थिति में पता नहीं चलता है परन्तु जब शरीर में रोग कारक (जीवाणु, विषाणु आदि) की संख्या अधिक हो जाती है तब जाकर उस रोग के लक्षणों का पता चलता है। जब व्यक्ति के शरीर में रोगकारक की बहुत कम संख्या होती है तो ऐसी स्थिति में रोग के लक्षण दिखाई नहीं देते हैं। किन्तु अब प्रारम्भ में ही इनकी पहचान पी सी आर (PCR) द्वारा उनके न्यूक्लिक अम्ल के प्रवर्धन (amplification) द्वारा कर सकते हैं PCR का उपयोग संदेहात्मक कैंसर रोगियों के जीन में होने वाले उत्परिवर्तनों का पता लगाने में भी किया जाता है। संदेहात्मक एड्स रोगियों में HIV की पहचान के लिये PCR आजकल सामान्यतया उपयोग में लायी जाने वाली विधि है। DNA या RNA अणुओं को जिन्हें रेडियोधर्मी अणु-प्रोब (Probe) के साथ जोड़ा हुआ होता है, जब इसके पूरक DNA के साथ संकरित करने दिया जाता है व क्लोन कोशिकाएं बनने लगती हैं तब उनकी पहचान आटोरेडियोग्राफी (autoradiography) द्वारा कर ली जाती है। क्लोनित कोशिकाएँ जिनमें उत्परिवर्तित जीन थे वह फोटोग्राफिक प्लेट पर नहीं उभरती हैं क्योंकि प्रोब व उत्परिवर्तित जीन आपस में एक-दूसरे के पूरक नहीं होते हैं। DNA प्रोब्स (DNA Probes)-DNA के ऐसे छोटे-छोटे खण्ड जो एक जैविक या अजैविक तंत्र में किसी जीन या एक लम्बे DNA अनुक्रम की उपस्थिति को ज्ञात करने में सहायक होते हैं, उन्हें DNA प्रोब्स कहते हैं। ये जीनों या विशिष्ट DNA अनुक्रर्मों को पहचानने के लिये अत्यन्त परिष्कृत एवं संवेदनशील साधन हैं। इनके द्वारा संक्रामक रोगों का निदान, भोजन में संदूषकों की पहचान, जीना को पृथक करना तथा अन्य सूक्ष्म जीवों के परीक्षण में किया जाता है। एलिसा (ELISA) तकनीक का उपयोग विषाणु, जीवाणु, माइकोप्लाज्मा, कवक जैसे जीवों की पहचान के लिये किया जाता है। यह अतिसंवेदी विशिष्ट परीक्षण है। इसका प्रयोग कुछ संक्रामक रोगों जैसे-एड्स, तपेदिक आदि की पहचान करने के लिए भी किया जाता है। एलीमा प्रतिजन-प्रतिरक्षी पारस्परिक क्रिया के सिद्धान्त पर कार्य करता है। रोगजनकों के द्वारा उत्पन्न संक्रमण की पहचान प्रतिजनों (प्रोटीनजन, ग्लाइकोप्रोटीन आदि) की उपस्थिति या रोगजनकों के विरुद्ध संश्लेषित प्रतिरक्षी की पहचान के आधार पर की जाती है। 7 f न

Benzer recombination 18 6.67 points What is the distance between x and y? You have a different set of phage that have mutations in different locations on the rII locus. Mutation x is on rIIA, and mutations y and z are on rIIB. Based on your complementation and recombination data for these mutants, you are unable to determine the exact order of y and z, so you do another recombination experiment to map the distance of y and z from x. Your results are shown below: 20 m.u. 2 m.u. 4 m.u. 5 m.u. None of these 19 6.67 points Which of the following maps best reflects the data drawn to scale?

The northern hairy-nosed wombat has experienced historical population declines, though the population has stabilized recently due to conservation efforts. While studying them, researchers noticed the following fluctuations in (effective) population size: Year 1: 100 individuals Year 6: 50 individuals All of your answers should be related to genetic variation, drift, and other related topics we covered in class. (9 points) Propose a specific plan of action to save the northern hairy-nosed wombat. Assume that the loss of genetic variation is the number one threat to this species. For your proposed plan of action, provide the reasoning as to why it will preserve genetic variation in the northern hairy-nosed wombat. For your proposed plan of action, what are some pitfalls you would have to consider? You may not be able to completely eliminate these, but you should be aware of them.
