सध्या बाजारात जननिक अभियांत्रिकीची अनेक उत्पादने आढळून येतात. उदा. इंटरफेरॉन, मानवाचे वृद्धीसंप्रेरक आणि मानवीय इन्स्युलिन. सन 1982 साली पुन:संयोजी जिवाणूने बनविलेले मानवीय इन्स्युलिन बाजारात विक्रीस आले. पूर्वी ही सर्व प्रथिने प्राण्यांच्या पेशीपासून शुद्ध केली जात होती. परंतु मानवावरील ही स्वरूपे त्यावेळी फार कमी प्रमाणात उपलब्ध होती. 1982 च्या पूर्वी मधुमेहात उपयोगात येणारी सर्व इन्स्युलिन केवळ गुरांच्या बोव्हीन व डुकरांच्या स्वादुपिंडापासून शुद्ध केली जात होती. ही सर्व इन्स्युलिन उत्पादके मांस कारखान्यात सह-उत्पादन म्हणून तयार व्हावयाची. इन्स्युलिनचा पुरवठा हा मांस कारखान्यातील पुरवठा व गरजेवर अवलंबून होता. पुन:संयोजी इ.कोलाय पेशीने व्यापारी तत्त्वावर तयार केलेल्या मानवीय इन्स्युलिनमुळे ते तयार करण्यात भविष्यात कमतरता राहण्याबाबत चिंता राहिलेली नाही. याशिवाय ज्यांना मधुमेह झाला आहे व ज्यांना बोव्हीन अथवा पोर्सीनचे वावडे आहे त्यांच्याकरिता मानवीय इन्स्युलिन अत्यंत उपयुक्त ठरेल. पुन:संयोजी डी.एन्.ए.चे तंत्र जीन थेरपीमध्ये महत्त्वाची भूमिका बजावते ज्यात ते प्रत्यक्षात सहभागी होऊन जीन साहित्यात फेरफार देखील करते. There are several products of genetic engineering now available in the market viz. interferon, human growth hormone and human insulin. In 1982, human insulin produced by recombinant bacteria was released for sale in the market. All of these proteins were previously purified from animal tissues. But human forms were available only in very minute quantities. Before 1982, all insulins which were utilized for diabetics were purified only from bovine of cattle and Porcine of pigs pancreas. These insulins were made available as by-products of meat industry. The insulin supply was, thus a function of supply and demand in the meat market. The commercial production of human insulin in recombinant E. Coli cells eliminated concerns regarding possible shortage of insulin in the future. In addition, this human insulin, was of particular importance to some diabetics who were allergic to bovine and/or porcine insulin. Recombinant DNA techniques play an essential role in gene therapy which involves the direct manipulation of genetic material.

पुढील दोन विधानांचा विचार करा : वरील कोणते विधान योग्य आहे ? Consider the following two statements : Now state which of the two above statements is correct ?

(a)मानवीय इन्स्युलिन 1982 पावेतो उपलब्ध नव्हते. / Human insulin was not available until 1982.

(b)तोपर्यंत इन्स्युलिन मांस कारखान्यातून मुख्य उत्पादन म्हणून उपलब्ध व्हावयाचे. / Insulin until then was the major product of meat industry.

1)केवळ (a) / Only (a)
2)केवळ (b) / Only (b)
3)(a) व (b) दोन्ही / Both (a) and (b)
4)(a) व (b) दोन्हीही नाही / Neither (a) nor (b)✓ Correct

Human insulin was successfully produced using recombinant DNA technology in 1978 (marketed in 1982), but prior to that, insulin was extracted from animal pancreases (pigs and cattle), not strictly meat factories as a primary planned product in that exact phrasing, making both statements inaccurate in their specific contexts.

Which of the following statements are false in the context of the given passage ?

(a)Aristotle told us that tree trunks add a new ring every year.

(b)All types of trees contain dark and light bands.

(c)Trees contain the record of their age only.

(d)Human beings have unlocked all the secrets contained in trees.

1)a, c, d
2)a, b, c
3)a, b, c, d✓ Correct
4)a and d

All four statements contradict the passage: (a) it was Leonardo da Vinci, not Aristotle, who suggested a ring is added every year; (b) the bands are absent in many tropical trees; (c) trees record precipitation, temperature, fires and more, not only their age; (d) the passage says 'if we only knew how to unlock its secrets', so we have not unlocked them all. Hence a, b, c and d are all false.
